Similar information can be found in the Installation Instructions that are shipped with every product. A Spanish version of these installation instructions can also be found on com. Station Input / Output Board The WeatherTRAK ET Pro3 series incorporates an 18-station input / output board with a minimum of 6-stations. The station count can be increased in 6-station increments by adding Station Keys. An additional blue LED will illuminate when the station key is properly inserted. 1 blue LED light = 6 stations enabled The hardware of your WeatherTRAK ET Pro3 series controller is comprised of the following components: Command module Power supply Station output board with rain sensor and optional flow sensor inputs. Stations can be increased in 6 station increments using a "station hardware key." Ground lug See Figure 1.2 for a detailed layout of the station output board. 2 blue LED lights = 12 stations enabled - 1 station key required 3 blue LED lights = 18 station enabled - 2 station keys required White LED = Flow enabled - flow key rquired It will take approximately 30 seconds for the controller to recognize the station key. Before programming additional stations, you must still increase the station count in the SETUP menu under Max Active Stations. Each station output has a screw-less termination that can accommodate wire sizes from 12 to 22 gauges. These heavy-duty terminal blocks can be opened and closed without the use of any tools. The station input/output board has two valve field common wire terminations as well as a dedicated master valve output and flow sensor input HydroPoint Data Systems, Inc. All rights reserved. WTETP3OMv Chapter 1 Getting Started

16 Diagnostic LEDs The station input / output board has several LED s to reduce field troubleshooting. Character Display AC 3V Flow ELEC COMM Meaning A yellow LED illuminated when 24 VAC is present on the station input / output board. See troubleshooting section if not LED NOT illuminated. A green LED illuminated when 3 VDC is present. See troubleshooting section if not LED NOT illuminated. A red LED illuminated when there is a flow alert. See troubleshooting section if LED is illuminated. A red LED illuminated when there is a station electrical alert. See troubleshooting section if LED is illuminated. A red LED illuminated when there is a communication alert. See troubleshooting section if LED is illuminated. Flow Sensor Inputs The WeatherTRAK ET Pro3 is compatible with the following flow sensors: Data Industrial (Badger Meter) IR-220 series Creative Sensor Technology FSI-T Series Netafim Reed Switch Type Register Series Bermad 900 Reed Switch Type Register Series Flow sensor inputs match the red (+) and black (-) conductors respectively. Rain Sensor Inputs The WeatherTRAK ET Pro3 is compatible with the following wired and wireless models of rain switches or rain/freeze switches: Toro series Irritrol series Hunter Mini-Clik series Hunter wireless Rain Clik series The WeatherTRAK ET Pro3 is not compatible with the following rain switch models: Rain Bird Rain Check series Rain Bird tipping bucket RainMaster tipping bucket Water Conservation Services Rain Guard series A dedicated 24-volt VAC output and Rain Sensor input terminal block is located on the right hand and middle of this station board. The terminal block can be removed for faster and easier field installation. It is keyed to fit only one-way to avoid crossconnection. The 24 VAC terminals are not polarized and wire can be terminated in either terminal as needed when 24 VAC power is required. Definition of Terms ASF Assigned Station Flow This value represents a specific station s recorded or learned flow value once all flow monitoring functions have been programmed and will appear when flow monitoring is turned On. The ASF is displayed once the station flow is operated for a user defined period of time. An ASF will be displayed as UNK or unknown until a value has been recorded. Once recorded, the ASF can be changed by pressing the lower knob clockwise or counter-clockwise until the desired value is selected. The station corresponding SHFT or Station High Flow Threshold will also automatically change if the global station offset value has been set. Automated by WeatherTRAK An exclusive Station Mode that will automatically calculate runtimes, cycle and soak periods, and watering day patterns from user-defined site-specific data on a station-by-station basis. WeatherTRAK s exclusive Scheduling-Engine reflects the Irrigation Association s (IA) best management practices (BMPs) for irrigation scheduling. For more information, see Chapter 2 Minimum Programming Requirements. Days/Times These terms represents the day pattern (any one of seven) and start times that can be assigned to each program. For more information, see Chapter 2 Minimum Programming Requirements. Efficiency Reflects how well a sprinkler applies water over a given area in percentage. The higher the percentage, the more efficiently water is applied. Every sprinkler type has a different efficiency percentage based on its design, pressure and flow delivery of the piping system. Default efficiencies have been attached to each sprinkler type and can be modified as needed. For more information, see Chapter 3 Assigning Stations to a Program. ET A reference value used to measure the amount of transpiration of healthy cool season grass to determine watering requirements. ET is determined via an algorithm of five environmental variables: Temperature Wind Dew point Solar radiation Evaporation ET is measured in inches/day but can also be expressed in inches/week or inches/month. For more information, see Chapter 6 Other Programming Functions. Chapter 1 Getting Started hydropoint.com

17 Kc Crop coefficient references a plant s specific and known transpiration value. Default Kcs are associated with general plant types and cannot be modified. For more information, see Chapter 6 Other Programming Functions. Max. Active Stations The maximum number of live stations programmed with runtimes. This is not the actual maximum number of physical stations inputs within of a controller. For example, the controller size is 36 stations with 33 stations in use, leaving 3 unused. The maximum active number of stations would therefore be 33. If all 36 stations were identified designated as being active, then the additional 3 stations that aren t in use would skew the watering window. Maximum Allowable Depletion (MAD) A reference value of 50% of the available soil moisture; it s used to determine when to apply supplemental irrigation. Plant material s ability to absorb water at lower MAD values is often times constrained by plant physiology, which can lead to severe plant stress and loss. For more information, see Chapter 6 Other Programming Functions. Rain Pause A user-defined delay period to suspend all scheduled irrigation starts after a rain event. When in Rain Pause, the controller will not initiate any scheduled start times. The selectable time period is from days. The controller will automatically decrement the rain pause days at Program A's start time until the defined time has expired. The exception to a Rain Pause suspension is when "Usable Rainfall" under STATIONS is selected as "None" for any station. For more information, see Chapter 6 Other Programming Functions. Rain Service Rain Service is an optional service to automatically suspend scheduled irrigation based on raunfall amounts. This is a separate service that can be activated in addition to ET Everywhere and is available on a limited basis throughout the United States. To determine if Rain Service if available for your area, call your HydroPoint Customer Service representative (800) When activated, Rain Service suspends scheduled irrigation automatically for a given period of time based on the intensity and duration of the storm. For more information, see Chapter 6 Other Program-ming Functions. Microclimate Sometimes referred to as exposure, or the amount of sunlight that a particular valve zone receives during the day. For more information, see Chapter 3 Assigning Stations to a Program. Optimized by WeatherTRAK An exclusive WeatherTRAK water day pattern selection that will automatically calculate water day patterns on a station-bystation basis. In this mode, the highest level of water savings, runoff reduction and optimum plant health is obtained. For more information, see Chapter 6 Other Programming Functions. Precipitation Rate The amount of water a sprinkler applies within its rated coverage area over a specific period of time, measured in inches/hr. A sprinkler with a low precipitation rate (a full circle rotor head as an example having.50"/hr) will reflect a longer runtime. As a contrary example, fixed spray heads commonly have higher precipitation rates between 1.70 to 2.00"/hr and will reflect shorter runtimes. For more information see Chapter 3 Assigning Stations to a Program. Program WeatherTRAK offers multiple programs. Each program can be assigned a start time, up to 20 cycles, one of seven water day patterns and a second start time for High ET when applicable. Programs are assigned on a station-by-station basis. Each station can only be assigned one program. For more information, see Chapter 2 Minimum Programming Requirements. Note: Rain Service updates are sent on a daily basis along with ET Everywhere Service. There is potential for a 24-hour delay in suspending irrigation after a rain event due to availability of rainfall data. Root Depth Each plant type has an associated root depth depending on the species, growth characteristics and accessibility to supplemental water. For more information see Chapter 3 Assigning Stations to a Program. Note: To Fully maximize water savings for optimum plant health, Automated by WeatherTRAK program mode and an Optimized water day pattern is strongly recommended. Run Time An individual station's user-defined or automatically calculated runtime. It does not include totals for cycle and soak times. For more information see Chapter 2 Minimum Programming Requirements. Session Timeout The amount of time allowed on a web page. For example, if the session timeout is 5 minutes and no changes have been made to an open web page, it will close (timeout) returning to the weathertrak.net login page HydroPoint Data Systems, Inc.

18 SHFT Station High Flow Threshold This represents a station s high flow value above the station s assigned station flow which triggers a station high flow alert. For example, a station has an ASF of 60 GPM and the global station offset is 20% or 60 x 1.20 = 72 GPM. If the WeatherTRAK controller measures more than 72 GPM for the user defined delay period it will post a station high flow alert, stop irrigation for that corresponding station and move to the next station in the program sequence. Any station s SHFT can be edited by selecting the specific station and using the upper and lower knobs. In this example, this station may have a SHFT higher or lower than other stations using the global station offset value. Station Mode Each individual station can be assigned a station mode, which is an underlying sub-function of a program. For example, station 01 is assigned to Program A, the station can be assigned to any one of the following four station modes: Automated by WeatherTRAK In this station mode, site-specific landscape and irrigation parameters are completed for each remote control valve or station separately. In this mode, the controller will automatically calculate station runtimes, cycle and soak periods. User w/ ET In this station mode, the user enters the runtimes, number of cycles and soak periods. The daily weather update then adjusts the runtime up or down based on today s ET. This mode is useful in localities with very strict watering limitations. User No ET In this station mode, the user enters the runtimes, number of cycles and soak periods. ET data is not integrated in this mode. This station mode is commonly used for plant (root) establishment and acts much like a conventional controller. Off In this station mode, a specific station can be turned off or suspended from automated irrigation until it is assigned to any one of the other three modes (as listed above). An example of this feature might be a station that has a broken head or requires a specific pesticide application and therefore needs to be shut down for a few days. SETUP The programming functions under this menu position globally impact the usage of the controller. The minimum SETUP functions to properly operate the controller are as follows: Time Date Time Zone Auto Daylight Savings Max Active Stations Master Valve Type Assign a Station Output as a Pump Start. Stack or Overlap (Stack is the default setting) Set Maximum Back-up ET. For more information, see Chapter 2 Minimum Programming Requirements. Soil Type The United State Agriculture Administration has classified soil texture into 5 classifications (Sandy, Sandy Loam, Loam, Clay Loam, and Clay). Each of the 5 classifications has different infiltration or percolation rates as well as water-holding capacities. These soil types and known infiltration rates are used as part of calculating runtimes as well as cycle and soak times when using the Automated by WeatherTRAK mode. For more information see Chapter 3 Assigning Stations to a Program and Appendix B: Typical Soil Types. Sprinkler Type The irrigation industry has identified various sprinkler head types into several categories based on their design and usage. The Automated by WeatherTRAK mode incorporates these sprinkler categories along with associated precipitation rates and sprinkler efficiencies. For more information see Chapter 3 Assigning Stations to a Program. Slope Factor The relative steepness of a slope will impact cycle and soak times (along with soil type) when calculating a sprinkler runtime. Steeper slopes with low infiltrating soils such as clay, may have short runtimes and multiple cycle and soak periods compared to a sandy loam soil. The ability to qualify the amount of slope for each valve enables the scheduling engine to develop a more accurate runtime as well as cycle and soak times. For more information see Chapter 3 Assigning Stations to a Program. Chapter 1 Getting Started hydropoint.com

19 Usable Rainfall The WeatherTRAK ET Pro3 series allows you to choose between none or 100% usable rainfall on a station-by-station basis. The 100% setting is the default and means that all valve zones will use 100% of available rainfall (irrigation will be suspended during a Rain Pause). When None is selected, the controller will continue to irrigate ignoring a Rain Pause delay or rain switch (if installed and triggered). The None setting is commonly selected for valve zones such as those involving hanging pots or potted plants located under a roof or semi-porous cover. Water Day Pattern Each program can be assigned to one of the following water day patterns: Optimized by WeatherTRAK Water day patterns are automatically calculated for each station independently based on zone-specific programming and a 50% MAD depletion model. In this mode, the highest amount of water savings potential is achieved. Odd Watering exclusively occurs on odd calendar days. For months that begin and end in two consecutive odd days, the first odd day will not irrigate. Even Watering exclusively occurs on even calendar days. Interval From 1-31 days, 1 day interval is the same as everyday irrigation. Days of week (1-7 days) Sunday through Saturday identical to a conventional controller. Day of the Week By Month Same Sunday through Saturday pattern but for each week of every month. Off Suspends the watering pattern/plan of an entire program until it is reassigned to one of the other water day patterns listed above. Water Window A user-defined reference by program that represents a time frame in which a group of valves or all valves will be irrigated within. The minimum watering window is 1 hour and the maximum time frame is 23 hours, 59 minutes. WeatherTRAK offers a user-defined water window by program and the ability to water within or outside of the water window. The WeatherTRAK ET Pro3 has two start times per program, each with user-defined water windows from 1 to 23 hours, 59 minutes.

20 2 Minimum Programming Requirements ; This chapter is divided into three major sections: Section 1 Configuring Primary Setup Functions these are the minimum setup functions needed to allow the controller to begin irrigating automatically. Section 2 Configuring Secondary Setup Functions secondary setup functions that can be set once a program is entered to begin automated irrigation. Section 3 Selecting a Program This is the setup process to select one of four programs and establishing at least one start time, a water window duration and a water day pattern (day the controller will irrigate) as part of automatic scheduled irrigation. The ET Pro3 series offers four separate programs that can each be assigned two start times with separate water windows (in Overlap mode), including any one of 7 water day patterns. This section explains the minimum programming requirements to configure your ET Pro3 series controller for either a new landscape or an existing landscape. In this chapter you will learn how to: Select a program. Assign first start time and water window timeframe. Assign a water day pattern (any one of seven) to a program mode. Assign the Auto Day Exclusion option for Automated by WeatherTRAK day pattern only. Note: These minimum requirements do not include the Flow function, which is explained in Chapter 6. Note: For a description of the alerts that you may encounter while using your ET Pro3 series controller, as well as potential solutions for each, see Chapter 5: Alerts. The controller has a default start time of 12 midnight with a 16 hour water window. Once activated the controller may irrigate what appears to be a random station. The station operating is simply based on the default start time and where the station is in the programming sequence, according to the current time. Changing the start time will or resetting the water window based on site requirements will stop this occurrence. Section 1 Configuring Primary Setup Functions Once you have activated your ET Pro3 series controller, you are ready to make some initial configurations. These include: Setting date and time Setting time zone Setting maximum active stations Setting stack or overlap mode Setting maximum backup ET value 2013 HydroPoint Data Systems, Inc.

Setting the Maximum Active Stations MAX ACTIVE STATIONS 01 (User Defined) The default time is 12:00 a.m. This value should correspond to the actual number of valve stations that are going to be programmed. Chapter 2 Minimum Programming Requirements hydropoint.com

22 Press g or to set the station count between 1-48 stations. Note: If you set Max. Active Stations to a value higher than the actual number of valves connected, you may add unnecessary time to the watering window. This action may trigger a Water Window Alert. Note: If you set Max. Active Stations to a value less than the actual number of valves connected, you will prevent some of the valves from operating at all. Note: Do not count master valve, pump start or sensor inputs as active stations. ; The default setting is Stack where the programs run in sequence, consecutively one after another. In Stack mode, the first program will complete its entire schedule, followed by the next program regardless of its start time. This is useful in situations when delivery pressure or mainline sizes are inadequate to operate more than one valve simultaneously. In Overlap mode, programs will run in parallel. This means that if the first program is still running when the second program is scheduled to start, the two programs will run. ET Pro3 series controller allows several programs to operate simultaneously as long as the overall electrical draw does not exceed 3.0 amps. Note: Pressing at anytime while in the SETUP menu, will display the following screen: STA CONFIG FOUND ACTIVE Press g to Overlap to set your controller to Overlap mode. Otherwise Press to move to the next step. Select Master Valve Type The character display for this function is: Character Display STA CONFIG FOUND ACTIVE Meaning Set by WeatherTRAK at the time of manufacture. The number of physical station outputs on the back panel. The maximum number of userdefined active stations that will be programmed. If Max. Active Stations has not been designated, then its value will be displayed as 00. When Max. Active Stations exceeds the number of Found stations, a Hardware Alert will be triggered. To Set the Stack or Overlap Mode STACK or OVERLAP Stack MASTER VALVE None The ET Pro3 series controller features a dedicated master valve output as a standard feature. The master valve is used to isolate the mainline or a portion of the mainline when programmed as part of flow monitoring. It enables your ET Pro3 series controller to troubleshoot and isolate pipe malfunctions or other types of failures. The default value is None. The default setting for this feature is None. Two other choices are: Normally Closed Normally Open Press g or to select the desired option. When a normally closed master valve type is selected and a station is operated manually, the RUN menu will display the master valve is open in the RUN menu as follows: Your ET Pro3 series can operate in one of two ways depending on the hydraulic capacity, delivery pressure and other flow characteristics of your system HydroPoint Data Systems, Inc.

23 Select Pump Start Output ASSIGN PUMP START OUTPUT Not Assigned Section 2 Configuring Secondary Setup Functions The ET Pro3 series controller features the ability to assign any station output as a pump start. Once assigned, this station output cannot be assigned to a program or specific station functions. When a pump station assignment is made, the overall station count is reduced by one. The default value is Not Assigned and any station output 1 through the maximum station count of the particular controller can be selected. Note: A pump station assignment should not be counted as a station when determining Max Active Stations. Note: The pump start is assigned to all programs, and station or program exclusion is not available in this release. When a pump start is assigned to a station output and a station is operated manually, the RUN menu will display the master valve is open in the RUN menu as follows: Adjusting the display contrast Setting up the Run Time Valve Test Setting the Maximum backup ET Setting Up the Runtime Valve Test ; The ET Pro3 can continuously monitor for field wire integrity as an optional feature. When selected, the controller will automatically monitor for individual Station Over-current, System Over-current and individual No Connects wire faults at the beginning of each scheduled start time or manual watering. Alerts will be posted if any faults are found, but will be automatically clear these alerts at the next scheduled start time in case this was a one-time occurrence. Note: If a field wire integrity fault is found, the controller will stop irrigating the corresponding station and will continue to calculate depletion values for any stations that partially operated or did not run at all. To Set Run Valve Test Press SETUP. When set to Yes, your ET Pro3 series controller will run a valve test each time a station begins irrigating. When a valve fault is found, it will trigger a valve alert message notifying you of a problem. To change the value, press g to Yes. Setting the Maximum Backup ET Setting the Maximum Backup ET ensures that your ET Pro3 series controller will provide sufficient irrigation in the event that it loses communication with the ET Everywhere service and the Chapter 2 Minimum Programming Requirements hydropoint.com

24 controller is required to irrigate without ET updates. Backup ET values can be set from 0.50 to 3.99 per week in 0.10 increments. This is a two-part process. Part one sets the value to the left of the decimal, while part two sets the values to the right of the decimal. To Set the Maximum Backup ET Step 5: Press SETUP. Press until the display shows this: MAX BACKUP ET PART Note: You cannot set a maximum ET value of The maximum ET backup value includes seasonal curves based on the month of the year automatically.

If you don t know your Max Back-up ET, call WeatherTRAK Customer Service toll-free at (800) Section 3 Selecting a Program ; To irrigate any station on an automated irrigation schedule, stations must be assigned to one of four programs, each assigned with a start time and water day mode. This setup is completed in the DAYS/ TIMES menu. Once completed, stations and station modes are assigned to a Program. In stack mode, one start time and water window duration is selected for all programs allowing stations to be irrigated in numerical order. In overlap mode, Programs may have the same or overlapping start times and will water more than one station at the same time. In the ET Pro3 series, four programs can be irrigated at the same time if the irrigation mainline size and delivery pressure will support this requirement. For example, suppose 8 stations are assigned to Program A with a start time of 10:00pm and Program B is assigned to 10 stations with a start time of 11:00pm. Program A will begin to irrigate at the assigned start time followed by the first station in Program B at 11:00pm even if all of the stations assigned to Program A haven t finished irrigating. You may also use overlap mode to schedule drip irrigation during the daytime if it doesn t conflict with local water conservation restrictions where Programs can be configured to not overlap where separate start times and water window durations are required. Selecting a Program Select any one of four programs, A, B, C or D by pressing the DAYS/TIMES position. The first screen to appear should look like as follows: Press g to scroll and select other programs. The default day mode setting is Optimized by WeatherTRAK with a 9:00PM start time (S) and 16 hour water window (W) HydroPoint Data Systems, Inc. All rights reserved.

25 Exclude a Program from a Pump Start ; Some landscapes may require a booster pump to increase delivery pressure based on the operating pressure requirements of the sprinklers used. The factory default is that all stations are assigned to a pump start when a pump start is assigned in the SETUP menu. Often times low pressure sprinklers such as drip emitters or flood bubblers may not require additional pump station boost, therefore stations can be assigned to a program which is excluded from a pump start to save energy and avoid over-pressurization of the irrigation mainline. If overlap station mode is selected and a program with a pump start and a program without an excluded pump start have overlapping start times, the pump start will over-ride the excluded message. Note: Pump start exclusion cannot be assigned on an individual station basis which would result in cycling the pump on and off shortening the life expectancy of the booster pump and wasting energy. When a pump start is assigned to a station output the following screen will appear: To exclude a program from a pump start, press g. When a program is excluded from a pum start and a pump start station is assigned, it will be indicated in the PREVIEW menu under "Station Data" as shown in the following screen display: Assigning a Start Time and Water Window Length Assigning a start time and a water window length requires the following steps: Select a start time (hour) Select a start time (minute) Select a watering window (hour) Select a watering window (minute) Set Start Times/Water Windows Each program can have watering windows from 1 hour to 23 hours and 59 minutes. Water windows are exclusive to their assigned programs and will not impact the water windows of other programs. Your ET Pro3 series controller will automatically calculate the end time based on the start time and the length of the water window. The display of the end time here helps manage unique watering requirements by showing when other program starts must occur. This is particularly useful when operating your controller in Overlap mode. Your ET Pro3 series controllers have the ability to set a second start time (High ET) for areas that are subject to extreme daytime temperatures and/or high winds. In this application, shallow rooted plant material and new landscapes are at risk of depleting their soil moisture before the next scheduled irrigation cycle, causing plant stress. The High-ET start time is a schedule syringe cycle designed to apply 25% of the 1st start time s run times to all stations where it is needed. The following paragraphs will take you through a step-by-step process of setting the 1st and if necessary a second High-ET start time and water window. Again, start times and water windows are set by program, allowing you to set four different first and second water windows. To Select a Start Time (Hour and Minutes): Press DAYS/TIMES. SET STARTS WINDOW PRG A Skip (Button to View) Press DAYS/TIMES until the display appears as follows: WATER DAY MODE PGR A Optimized by WeatherTRAK If the appear: Button is pressed, the following screen will START 1 S12:00am W12:00 HiET 2 S7:00pm W:05:00 Press g or to select a program. The text in parentheses shows the default Program mode (Optimized by WeatherTRAK), the start time of 12:00am and the default watering window of hours. In this screen you can view both the first and second start times and water windows specific to a program. This screen is view only and cannot be changed. Chapter 2 Minimum Programming Requirements hydropoint.com

26 Step 5: Note: The maximum water window length is 24 hours. Entering two watering windows that exceed this value will trigger an Alert (note the word Overlap in the third line of the display because the first and second start times overlap). Entering two start times that overlap will also trigger an overlap warning on the third line. Press SELECT to edit: The Hour portion will be underlined. Press g to change the Hour value to the hour you want irrigation to start for the program: Press to change the minute value. Assigning a Water Day Pattern to a Program The ET Pro3 series has seven different water day patterns to choose from: Optimized by WeatherTRAK The pattern in which the watering days are automatically determined for each station as its individual depletion value reaches 50%. Odd days The pattern where watering days are based on oddnumbered calendar days. Even days The pattern where watering days are based on evennumbered calendar days interval day The pattern where watering days are offset by an interval of 1 31 days. A value of 1 for this means that the program will run everyday. Days of the Week Sunday through Saturday Days of the Week by Month Set days of the week, Sunday-Saturday, for each month of the year. Off Step 6: Press g to change the minute value to the minutes after the hour you want irrigation to start for the program. Setting a Watering Window (Hour and Minutes) Press to set the water window. The display will show the hours portion of the water window (WIN) underlined. Press g or to scroll through the water window hour settings for the selected program. The range of water window is 1 hour to 23 hours and 59 minutes. Press to scroll to the next screen to complete your selection or continue with the Minutes portion by pressing the until it is underlined. Step 5: Use the g to select the desired minutes (00 59). Note: Watering windows of less than 1 hour cannot be selected. Note: The maximum watering window is 23 hours and 59 minutes. Note: For new landscapes with shallow rooted plants, or seed or sod lawns, consider Interval water days of 01 (everyday) until the plant material has established. Note: The same water day mode can be assigned to different programs. For example, a parking lot around a commercial building is irrigated with recycled water. The irrigation schedule must start and end between specific times. Assigning it with other stations could increase the water window outside of the restriction. Therefore, all other remaining stations could be assigned to another program with a different start time and water window but the same water day pattern.

Press g or to select one of the programs. Press to scroll to the next screen to complete your selection. Configure Usable Rainfall Your ET Pro3 series controller has the Usable Rainfall feature to calculate how much of the reported rainfall is usable for a given station or for all of the stations on a given valve. You may program to ignore either all or a portion of the rainfall data gathered on a station-by-station basis. This is especially useful in situations where specific stations or valve zones are located under a roof or a porous overhead where little or no rainfall is usable. This function is available in all program modes including User mode without ET. (however, in User modes the values are NONE and 100% only) If a rain sensor is used and specific stations are selected to use none of the usable rainfall, scheduled irrigation will continue to be applied. The same principle is applied for user defined rain delays. Press STATIONS. Press until the display looks like this: USABLE RAINFALL STA % Use the Water Window In Start Times/Water Days, a water window was established as part of the first start time.

44 Communication Alerts Summary Alert Type Severity Definition / Possible Causes Major ET has not been received for 5 days. Possible causes: Improper microzone has been assigned to the controller. ET Subscription has expired. Major The controller has not communicated with the WeatherTRAK Central server recently. Possible cause are: Controller AC power has been turned off or has been disconnected. Two-way phase integrities are low. Controller Action Possible Remedies Call HydroPoint Customer Service to verify the microzone and ask for a new ET signal to be sent. Confirm the ET message has been received. Restore AC power if lost. Verify phase integrities. Clearing Alert No ET Communication (CM) The controller continues to irrigate all stations using the last received ET message for 4 days. After 4 days the controller will use the backup ET. Alert will automatically clear once a new ET message is received. Controller Offline (OFL) Unless the power is off, the controller will continue to irrigate as scheduled, however, the controller may not receive ET messages and the controller may no longer be synchronized with the web site. Alert will automatically clear when communication with the server is re-established. Program Alerts Summary Alert Type Water Window (WD) Severity Definition / Possible Causes Minor The user defined water window is too short for the number of stations assigned. Possible cause: Current weather conditions require calculated run times that exceed the length of the water window. Minor Some stations are assigned to a program that has too few days of irrigation. Possible cause: Current weather conditions require more frequent irrigation. Controller Action Possible Remedies Increase the length of the water window in the DAYS / TIMES menu. Assign some stations to another program. Clearing Alert The controller will proportionately reduce all station runtimes to fit within the user-defined water window. The landscape may be at risk due to insufficient irrigation. Re-programming the controller will probably clear the alert. Water Day (DY) The controller continues to irrigate, trying to compensate by extending runtimes where possible. The landscape may be at risk. Change the Program (DAYS/TIMES menu) to increase the number of water days. Assign stations to a program which has more water days. Re-programming the controller will probably clear the alert.

46 Alert Definitions Flow Alerts The ET Pro3 can monitor for many separate flow conditions during scheduled and non-scheduled irrigation when connected to a compatible flow sensor. In automated or manual modes the controller will post any one of the following flow alerts; Mainline Break Alerts (catastrophic mainline failure) Station High Flow Alerts No flow alerts Leak detection alerts. Definitions of each of the following alerts are listed below. ; The expected controller behavior when setup is as follows: When the mainline break threshold is exceeded a Mainline Break Test is performed. A Mainline Break Test operates the configured master valve and pump start, but no stations for the duration of the Mainline Break Delay. After the Delay, if the Flow is less than the Mainline Break Threshold, irrigation resumes on the next Station. If, however, the Mainline Break Threshold is exceeded, an Mainline Break Alert is declared on the master valve and all irrigation stops. When the Mainline Break Test is operating, the text MBTST appears in the blinking Alerts field in the lower right-hand corner of the screen. The controller will continue to calculate depletion for all stations that were interrupted or did not irrigate and will give them priority once repairs are made and the alert is cleared at the controller. The controller will clear this alert at the next start of Program A. If the break continues to exist, the alert will be re-posted until the break is fixed and the flow alert cleared High Flow Alerts Mainline Break Alert The ET Pro3 can monitor for an irrigation mainline break continuously during scheduled and non-scheduled irrigation. A userdefined mainline break threshold in GPM and a delay period is minutes (default 3 minutes) can be established to monitor exclusively for mainline break conditions. Note: The mainline break threshold is typically 20% higher than the station with the highest GPM demand. Lower percentages could trigger false alerts and stop scheduled irrigation unknowingly and place all or portion of a landscape at risk. Main Leak Alert The ET Pro3 will monitor for mainline leaks during non-scheduled or scheduled irrigation. Station High Flow Alerts The ET Pro3 can monitor individual station flow rates when the corresponding station s flow parameters have been learned and stored within the controller. This is a separate process that can be found in Chapter 7- Flow Monitoring. The station high flow threshold can be set in one of three ways: A global percentage applied to learned station flow values from 5-80% in 5% increments (factory default is 20%), or User-defined thresholds in 1 GPM increments from GPM on an individual station basis, or A combination of both global percentage values for some stations and user-defined thresholds for other stations. Note: The controller has the ability to learn the flow rate of each station independently. This learned-flow valve can be edited if needed in 1 GPM increments. The controller does not distinguish between a Learned Flow values vs. a User-defined value both are identified in the controller screens as Assigned Station Flow Chapter 4 Alerts hydropoint.com

47 ; The expected controller behavior for monitoring High Station Flow is the same in both stack and overlap modes. When the station s high flow threshold is exceeded after the delay period (either the global percentage or user-defined high station flow threshold in GPM), the controller will immediately post an alert and stop all operating stations. The controller will then move to the next station(s) in the programming sequence, posting an alert for the station(s) previously running. The controller will continue to calculate depletion for the station(s) that partially ran before this alert was posted. The field issue should be resolved and the alert cleared to avoid stress or potential loss to a portion of the landscape. Leak Detection The ET Pro3 series controller can monitor for leaks during nonscheduled irrigation or scheduled irrigation when no irrigation is operating (long soak times). Note: The Leak Detection threshold is typically slightly above the expected flow rate of a hose bib or quick coupler. If the irrigation system also is used to fill a water feature, the leak detection value should be slightly higher than this fill rate. To determine the fill rate shutoff all operating stations and press the M knob to the FLOW menu to observe the Measured Flow recorded by the flow sensor. No Flow Alerts The ET Pro3 series can monitor for No Flow conditions for each station independently. An example of this is an isolation valve is closed in the mainline or on the backflow preventer or a pump station fails to start where irrigation should be operating but the flow sensor is not recording flow real-time flow data. ; Note: The No Flow threshold setting in a global value in GPM that is generally 15-20% lower than the station with the lowest flow rate. The expected controller behavior for monitoring High Station Flow is the same in both stack and overlap modes. When the station s high flow threshold is exceeded after the delay period (either the global percentage or user-defined high station flow threshold in GPM), the controller will immediately post an alert and stop all operating stations. The controller will then move to the next station(s) in the programming sequence, posting an alert for the station(s) previously running. The controller will continue to calculate depletion for the station(s) that partially ran before this alert was posted. The field issue should be resolved and the alert cleared to avoid stress or potential loss to a portion of the landscape. If three consecutive No Flow Alerts occur, the controller will stop all scheduled irrigation until the next scheduled start time of Program A. If the No Flow field condition persists the alert will be re-posted. ; The expected controller behavior for monitoring a Leak Detect or Extended Leak detection is as follows: When the Leak Detection threshold and user-defined delay period is exceeded the controller will immediately post a Leak Detect Alert. No further action is taken by the controller which is the expected behavior for a controller using a Normally-Open master valve. If Extended Leak is configured with a user-defined delay period (having a range of minutes in 1 minute increments) and the Leak Detect threshold is exceeded continuously for that period, the controller will post a second Extended Leak Alert and close a normally open master valve. The master valve will remain closed until a station is operated manually or at the next scheduled start time. If the leak stops during the Extended Leak delay period, the Extended Leak counter will reset automatically and the timer will resume its delay countdown if a leak reappears. The field issue should be located, resolved and Leak Detect Alert cleared to avoid stress or potential loss of the landscape. Slow and undetected leaks can result in slope failure or other significant property loss and should be addressed quickly HydroPoint Data Systems, Inc. All rights reserved. WTETP3OMv Chapter 4 Alerts

48 Valve Alerts The ET Pro3 series can monitor for valve wire integrity as part of scheduled irrigation as a one time event, or continually, depending on user requirements. In automated or manually operated modes, the controller will post one of the following Valve Alerts: Valve Shorts Valve Over-current Valve No Connects System Over-current If there is an Alert on a Station Valve, the Controller will not operate that Valve until the Alert is cleared, hopefully after the condition is corrected. Alerts can be cleared by pressing the button on any Valve Alerts Screen. Note: If there is an Alert on an MV or PS Valve, all irrigation stops until the condition is corrected and cleared.. The last Valve Status Screen indicates status of a special type of Valve Alert called the System Over-Current (SOC) Alert. The SOC Alert is covered in a separate paragraph later in this document. ; WeatherTRAK ET Pro3 series controllers provide field wiring troubleshooting techniques not found in competitive control products. These are intended to assist a user to quickly and proactively isolate a field wiring problem before stress to a portion or all of the landscape occurs. These functions can be set to check automatically every time the controller irrigates or addressed during periodic maintenance checks of the irrigation system. The alerts are posted in real-time to the controller and (when central capability exists) WeatherTRAK Central software as well as an option of receiving these or a portion of alerts via or as a text message to a cell phone. Valve Alerts can be viewed in the Alerts Menu on the View Valve Status Screen. Valve Alerts indicate electrical problems with any station, including Master Valves (MV), and Pump Start (PS) (when assigned as a station valve). The ET Pro3 series represents several different hardware platforms with different controller software versions. The following explanation of Valve Alerts attempts to identify how different hardware platforms will have different current and alert reporting thresholds. To upgrade your current controller software to the most current software version, call HydroPoint Customer Service or support@hydropoint.com and request a Controller Software Updater device which must be connected into the controller in the field. This device will preserve all existing programming data and will update the underlying controller software is approximately 10 minutes. Types of Valve Alerts There are 4 types of Valve Alert conditions, each indicated by a 2-character acronym. Character Display Meaning -- The valve is operating correctly (OK). NC OC SH The No Connect Alert (NC) indicates that the valve wiring measures a low current. This is typical of a common wire to several valves or an individual pilot wire when broken. An NC Valve Alert will also occur when a field wire is not physically terminated into a station output terminal particularly if Max Active Stations is set improperly. ET Pro3 hardware platforms less than 75 milliamps (ma) for any Station, MV or Pump Start. The Over Current Alert (OC) indicates that the Valve exceeds a current above a specific limit. This may be from a solenoid that is failing, a buried nick in the field wire insulation or when more than one solenoid is bridged to a single station output. ET Pro3 Station Output Board over 1000 ma for MV, Stations or Pump Start. The Short Alert (SH) indicates a serious electrical problem. The measured current is extremely high or a dead short condition was detected where the current is so high it cannot be measured accurately. ET Pro3 Station output board over 1.6A for any Station, MV or Pump Start. When a Valve Alert occurs, the Controller will typically not attempt to operate the Valve. Certain Valve Alerts on a Normally Open MV are an exception to this rule. This is because a Normally Open MV is not energized during normal operation. Chapter 4 Alerts hydropoint.com

49 Valve Tests and Valve States Valve States are results from a Valve Test. These screens are located in the MANUAL Menu under Valve Test. Valve Tests are run to determine whether or not a valve circuit is in proper operating condition. Each station has an associated Valve State that is the result of measuring current during the Valve Test. A valve s state or status will indicate an Alert condition when that valve s wire circuit is not in proper condition. When a Controller is powered-up, all valve states are set to the Not Tested state. All Valve Alerts are set to the or OK state. The first Valve Test is run within 30 seconds after startup. If Scheduled or Manual irrigation starts before that time, the Valve Test is run before irrigating automatically. Note: Valve Tests are run on all configured valves at least once a day, typically just prior to the Program A Water Window 1 Start Time. During a Valve Test, each valve is energized individually for 192 milliseconds. This allows the current to stabilize for accurate measurement. At the end of that period, the current measurement is recorded and the Valve s State is determined. The Valve is then de-energized and the test moves on to the next configured Valve. Valve States provide more detail than Valve Alerts. For example, there are several types of NC (No Connect States), each of which is specific to a particular type of Valve. In each case the threshold used to determine the State are the same as the thresholds indicated in the preceding Valve Alert Table, i.e. any No Connect indicates that the current measurement is less than 70 ma for the ET Pro3 The table below has a column for Possible Valve Alerts. Whether or not a specific Valve State is actually a Valve Alert depends in most cases on the Runtime Valve Test (RTVT) configuration setting. RTVT is discussed in the next section. Character Display Possible Valve Alerts Meaning? no alert The valve has not been tested. This occurs; (a) immediately after startup and (b) while a Valve is being tested. -- OK The valve is operating correctly (OK). NC NC The Valve measures low current. A valve common wire or individual station wire may be broken. A field wire may not be physically connected in a station output terminal or Max Active Stations is set improperly. NI NC A Normally Open MV measures low current. The Controller will continue to operate because the normal operating state of this type of MV is de-energized. NA NC A Pump Start Station measures low current. The Controller will operate this valve normally anyway, because the Pump Start often takes longer to reach operating current and may exceed the 192 millisecond delay time before it stabilizes. MO OC A Normally Closed MV measures high current. MI OC A Normally Open MV measures high current. The Controller will continue to operate because the normal operating state of this MV type is de-energized. SO OC A Station (irrigation or PS) measures high current. SH SH A Valve measures extremely high current. Operation of this Valve without repairing the condition may result in damage to the board. SF SH A Valve causes a dead short condition. Current is so high, it cannot be measured accurately. Operation of this Valve without repairing the condition may result in damage to the board HydroPoint Data Systems, Inc. All rights reserved.

50 Runtime Valve Test Configuration Setting Troubleshooting with the Manual Diagnostics Screen ; The WeatherTRAK ET Pro3 default setting is to conduct a valve test prior to the start time of Program A automatically. A second option is to press RTVT- Off and manually run a Valve Test when you believe there is a wring problem as a troubleshooting tool to quickly isolate the problem. Before pressing RTVT Off, be aware that if the damage to the station output board occurs (that would have been protected by having the RTVT- On, it will not be covered under the Product Warranty. ; In v6.3 controller software there are two methods to troubleshoot a suspect valve field issue both found in the MANUAL menu. The first method is when operating a station manually in any one of the three manual options, 1) Specific Stations, 2) All Stations and 3) Stations Assigned to a Program. When a suspect station is operated manually from this submenu the controller will automatically display its measured current in milliamps (ma). Using the tables above you may quickly determine and isolate the field issue, then take corrective action as needed. Runtime Valve Test (RTVT) is a configuration setting that is found in the controller s SETUP Menu. Note: Changing this setting has no effect on Valve States. Valve States are determined by the results of a Valve Test only, and have no relation to the Runtime Valve Test setting. The Runtime Valve Test setting affects Valve Alerts only its expected behavior is as follows: RTVT Off With RTVT Off, the only Valve States that generate Valve Alerts are the SH type Valve States SH and SF. Both of these States result in SH Alerts. The controller will not operate stations with SH alerts. RTVT On - default value All NC, OC, and SH Valve States produce associated Valve Alerts and may stop irrigation. The NC, NI, and NA Valve States generate NC Valve Alerts. The MO, MI, and SO Valve States generate OC Valve Alerts. The SH and SF Valve States generate SH Valve Alerts. A second method is to use the Manual Diagnostic submenu. The Manual Diagnostic menu is located in the MANUAL menu. On this Screen, a user can troubleshoot Valves, including the MV and PS Valves. While the Valve is operating, the Valve s measured current in ma is shown on Line 2. The right-hand side of Line 1 shows the Valve s measured Valve State. The System Over-Current Alert ; This feature is intended to prevent blowing a fuse when too many stations are operating at the same time. In many instances it can be considered current or electrical optimization of the available transformer for this hardware platform. The System Over-Current (SOC) Alert is not a normal Valve Alert and generally may only appear is the controller is set to Overlap mode when multiple stations are operated simultaneously. Note: All Valves displayed on this Screen are operating correctly. They do not have Alert conditions that prevent irrigation. Instead, the SOC screen indicates that the Controller attempted to operate a combination of valves that exceeded a total current threshold of 1600 ma. The estimation is based on the current that was measured for the individual Valves during the last Valve Test. Chapter 4 Alerts hydropoint.com

51 The SOC Alert arises when: 1. The Controller is operating correctly and a new Valve is about to energize. 2. The Controller adds the new Valve s last measured current to the total ma now being measured by the current combination of operating Valves. 3. If the expected total current is greater than the SOC limit, the Controller will remove at least 1 Valve from operation to reduce the expected total so that it is under the limit. In some cases, more than 1 Valve may be dropped from operation. 4. Valves are dropped in a priority order until the expected total is acceptable. Manual Stations are removed first If the word ALERT is observed to be flashing in the lower right hand corner of any screen and you have turned ALERTS menu, the display appears as follows: FL VL CM WD DY HW SB -- ER ER -- --=OK ER=Error ER denotes an Error or Alert for that specific category. To review the details of the alert, press. Note: Some alerts have two sets of display screens. Make sure to scroll the second page to view all alert messages. Stations in Auto Mode are next, with the least depleted Station removed first. Auto Stations are given high priority because they can typically be expected to recover lost irrigation through the Scheduling Engine s depletion algorithm. If the expected current is still too high, Stations in User with No ET are next. Stations with higher runtimes are first.

56 ET Pro3 Flow Monitoring Hardware Requirements 5 Flow Monitoring In this section you will learn about: ET Pro3 flow monitoring hardware requirements Flow monitoring capabilities/setup Your ET Pro3 series controller is capable of flow monitoring, response, and alert notification as standard features. The minimum hardware requirements for this feature are: A WeatherTRAK ET Pro3 flow key installed in the controller A compatible flow sensor A two-wire communication path from the flow sensor back to the controller If a wireless flow sensor is used, confirm consistent communication between the flow sensor and controller Your ET Pro3 series controller is compatible with Data Industrial IR-series and Creative Sensor Technology flow sensors specifically designed for irrigation applications. A continuous pair of colorcoded wires from the flow sensor to the flow sensor input in the WeatherTRAK ET Pro3 station output board is required. ; The ET Pro3 series controller offers several flow monitoring functions noted as: Learning, storing and alerting individual station flows. Alerting of a mainline break or mainline leak which is independent of individual station flows. No Flow monitoring for each station independent of one another. Leak Detection during non-scheduled irrigation or scheduled irrigation when no irrigation is operating. Extended Leak Detection for sites that incorporate normally open master valves. All flow setup functions must be completed at the controller and are not presently supported from the web application but are planned in the next software update of Remote alert notification to receive an and/or text message for any flow monitoring activity can be setup on central web application. Flow monitoring requires a compatible flow sensor as noted. The controller measures the pulses sent to it directly from the flow sensor without the need for a flow monitor. All flow monitoring values are set-up under the FLOW menu function. You can view the Flow Data function under the PREVIEW menu to check the Flow values that have been entered. For more information on the PREVIEW menu, see Chapter 6. Compatible Flow Sensors The ET Pro3 is compatible with the following: Data Industrial (Badger Meter) IR-220 Series (PVC models) Creative Sensor Technologies FSI-T Series Netafim Reed Switch Register-type Series Bermad 900 Series Reed Switch Register-type Series 2013 HydroPoint Data Systems, Inc. All rights reserved. WTETP3OMv Chapter 5 Flow Monitoring

57 ET Pro3 Flow Monitoring Hardware Capabilities Your ET Pro3 series controller monitors for the following flow conditions: High flow or a catastrophic mainline failure Leak detection during scheduled irrigation soak times as well as non-irrigation schedules No flow monitoring during scheduled irrigation Individual station high flow Each flow condition shall has its own user defined threshold valve including Off, as well as monitoring delay time period. The controller constantly monitors for these conditions, explained below: Your ET Pro3 series controller can monitor for each of the following flow conditions independently of one another; Mainline break or mainline leak Individual station flows No flow on an individual station basis Leak detection during non-scheduled irrigation or scheduled irrigation when no irrigation is operating Extended leak detection for irrigation systems incorporating normally-open master valves When setup, the controller will continuously monitor each flow monitoring function listed above. Flow monitoring functions operate independently from one another, allowing one or more flow functions to be turned Off depending on user needs or site conditions. Flow Monitoring Definitions The following paragraphs define each of the flow monitoring features. Mainline Break The ET Pro3 series can monitor for a mainline break continuously during scheduled irrigation. A flow value in gallons per minute (GPM) can be entered (1-995 GPM) along with a delay period in minutes (1-6 minutes) before the controller will begin alert and response measures. The mainline break threshold value is commonly 20% higher than the station with the highest flow rate. For example if a system had a station with a maximum demand of 50 GPM, a mainline break threshold of 20% would be 60 GPM. When the mainline break threshold and delay period are exceeded, the controller will immediately halt all scheduled and manually operating stations. The controller will then restart the delay period and test the master valve and/or pump start station independently. If the mainline threshold value continues to be exceeded after the test ends, the controller will immediately close the master valve, post a mainline break alert and stop all scheduled irrigation until the alert is cleared at the controller or when the next scheduled start time occurs. After clearing, the alert may re-appear if the mainline break condition persists. Clearing the mainline break alert without addressing a field condition will result in another Mainline Break Alert. The controller will continue to calculate depletion values for any stations that did not operate after a Mainline Break alert has been triggered. Station High Flow The ET Pro3 series can monitor individual station flow rates once the Learned Flow functions are setup and individual station data is collected. This feature will function in both stack and overlap modes. If multiple stations are operating at the same time and the accumulated flow of these stations exceeds the Station High Flow Threshold of all stations, the controller will stop all irrigation. The controller will post a Station High Flow Alert for all stations currently irrigating and move to the next sequence of valves in the irrigation schedule. The Station High Flow Threshold can be applied globally to all stations in 5% increments from 5-80% or in 1 GPM increments up to 999 GPM for any station. It is possible to use both global percentage values for some stations and specific user defined flow thresholds for other stations. The controller global default setting is 20% above a stations Assigned Station Flow. Assigned Station Flow can be either the Learned Flow or a User-defined Flow value. Note: If additional sprinkler heads are added or deleted and/or sprinkler nozzles are changed, the station s new flow rate must be re-learned for proper operation. Station High Flow monitoring can be disabled for this station until this is done, or the user can decide to let monitoring continue with the same threshold values. No Flow When the controller is running a scheduled irrigation program by electrically opening a valve and no flow is observed by the flow sensor, the controller will wait for one minute. If no flow has occurred within this timeframe, the controller will close the valve and will move to the next valve in the programming sequence. If by the third valve opening a no flow condition persists, the controller will immediately halt all scheduled irrigation and trigger a no flow alert. No irrigation will resume until either the no flow condition is repaired or the no flow alert is cleared. No Flow is most effectively used in Stack mode. Chapter 5 Flow Monitoring hydropoint.com

58 Leak Detection A Leak Detection threshold value is entered as part of Flow setup. To detect leaks, the controller monitors for any flow during both scheduled and non-scheduled irrigation and during soak times between irrigation cycles. When a leak threshold is exceeded, Leak Detect Alert is triggered. Scheduled irrigation will continue. If the leak increases in volume it will eventually become a high flow condition and irrigation will be stopped. Note: If maintenance at your site frequently requires periodic manual operation of valves or the use of quick couplers for irrigation of infields or for wash-downs, the leak detect should be set above these estimated flows to avoid triggering a Leak Detection alert. Extended Leak Detection This feature is primarily for irrigation systems that incorporate normally open master valves where controller action can be addressed when a continuous leak occurs. Extended Leak Detection is a part of Leak Detection which must be setup to operate and alert. Extended Leak allows for periodic use of the irrigation system such as window washing, pond filling, or other tasks where non-irrigation water may be required. An Extended Leak value of 1 minute to 240 minutes is entered in 1-minute increments allowing for a delay period. Flow is monitored during this period. If the Leak continues throughout the period, once the delay period is exceeded, the controller will immediately post an Extended Leak Alert and close a normally open master valve. The master valve will remain closed until the next scheduled irrigation start time or a station(s) is manually operated. An example of how this might occur is as follows: A window washer has connected a hose into a quick coupler to fill washing equipment during non-scheduled irrigation. If the flow threshold and time delay are exceeded, the controller will post a Leak Detection alert. If the window washer leaves the hose on and the Extended Leak delay period is exceeded, the controller will post a second Extended Leak alert, a Mainline Leak alert and close the master valve. If the window washer were to shut-off the hose bib before the Extended Leak delay was exceeded, the controller would reset the delay timer. If a few hours later the same condition occurs again but this time exceeding the Extended Leak delay period, the controller would post an Extended Leak Alert and close a normally-open master valve. Flow Monitoring Setup In this section you will learn to: View "Measured Flow" in real time when any station(s) are operating Turn the Flow Mode from "Off" to "1" or "On" Maintain or change the Flow Alert Clearing from "Automatic" to "Manual" Select a flow sensor size to match what is installed in the field View or edit corresponding K and Offset defaults for the flow sensor selected Set Mainline Break threshold in GPM and delay period.

Press and hold to view the following screen: MEASURED FLOW (GPM) FM1: To change the default setting from "Auto" to "Manual", press g so the following screen will display. Note: If a user selects the Manual setting, extra attention should be paid to the Flow Alert conditions, particularly Alerts on the master valve. This type of Alert suspends all irrigation until repaired and cleared. Press to move to the next screen. Select Flow Meter Mode Press g until the display appears as follows: FLOW METER MODE Off In this screen you may only select the Flow Meter Mode "1" value (in future releases, additional flow meters will be supported). Press to scroll to the next screen. Set Flow Alert Clearing The ET Pro3 Smart Water Manger series provides two options to clear flow alerts. These are: Automatic clearing of any flow alert at the next scheduled Program A start time. If the flow alert condition persists a second flow alert will be posted or, Manual requiring stopping of scheduled irrigation when a flow alert is posted until manually cleared at the controller. If the Flow Alert is on a specific station and not on the master valve, irrigation can occur on the non-alerted stations. Note: The factory default setting is Automatic clearing at the next scheduled Program A start time. Set Flow Meter Size The Set Flow Meter Size screen displays as: SET FLOW METER SIZE 1.00 The ET Pro3 series is directly compatible with Data Industrial IR Series and Creative Sensor Technology flow sensors in the following sizes. 1.00" 1.25" 1.50" 2.00" 3.00" 4.00" Insert Type Press g or until the desired size appears in the display. Press to scroll to the next screen. As soon as flow meter size is selected, it will be assigned its corresponding K and Offset values per Data Industrial published specifications. If you want to change either the K or Offset default values, select Edit for the appropriate value to enter a custom number. Each number is changed independently from one another and the default value can be observed on the right side of the display for comparison.

63 Set Station Flow This function allows the percentage station high flow offset value to be over-written with a user-defined flow threshold in gallons per minute (GPM). This can be applied to a single or multiple stations as needed. If skipped the controller will use the previous screen settings for all stations. ; An example of this might be a station with flood bubblers with low discharge rates along a pedestrian sidewalk that is subject to vandalism. The global setting of 20% is suitable for other stations within the controller but on this particular station the station high flow threshold needs to be a finer resolution to reduce a slip/fall potential from a broken sprinkler head. The controller will display an Assigned Station Flow (ASF) if the stations flow has been previously learned or if the user has defined a specific value. If the ASF says UNK, then this function is not used. The displayed ASF can be changed by pressing or if the displayed value is incorrect and should be a different value. If the user has set ASF to the Learned Flow value, the screen will look like: To use this feature press g once so the word Skip turns to Edit as shown below. Note: When ASF is equal to the Learned Flow value, the Learned Flow value (and ASF) can be cleared by pressing and holding the button for at least 2 seconds, while the ASF value is underlined. Press to select the corresponding station of where the Station High Flow Threshold (SHFT) is to be changed. Press to change this display to the following: Press to scroll to the SHFT as shown in the screen display below: Pressing the button on this screen will set ASF to the Learned Flow value of 7.2 GPM. The following table defines the display characters as follows: Step 5: The SHFT value in this example is the ASF value plus the 20% offset. Press g or to select the GPM value in 1 GPM increments from 1 to 999, resulting in a screen like: Character Display ASF: Unk SHFT GPM Meaning Assigned Station Flow - which is either Learned Flow or User-defined Flow Unknown Value - not used Station High Flow Threshold GPM value above Assigned Station Flow to signal an alert and controller response. Gallon per Minute (volume) In this case, pressing the button will return the SHFT to the ASF + offset value of 43.2 GPM. Note: The SHFT must be at least the same or higher than the ASF to avoid a false alert and potential risk to not watering this corresponding station. Note: The controller can display flow rates from 0.10 to 999GPM. Chapter 5 Flow Monitoring hydropoint.com

64 Select Stations to Learn Flow Before starting the Learned Flow function in the controller, select the station(s) to be learned. This can be a single station, a group of stations or all stations. Press until the following screen display appears: In order to set all stations to Learn, the user can press the button. The button sets all stations to Learn if any stations are not set. Pressing the button again will clear all stations (No Learn Stations). Set Delay Before Learning ; This features allows the user to select a global delay period before the controller begins to collect and store flow information. The range is 3-10 minutes in 1-minincrements. An example of where a longer delay period might be useful is on slope irrigation where the lateral pipe is end-fed from a remote control valve and it may take 5-6 minutes for the system to push out any air in the piping system and irrigate with a constant application. The delay period is also the runtime for the selected stations during Learning. Users can also set or clear stations individually. Press g to change the word Skip to Edit so the following display appears: Note: The factory default delay period is 3 minutes. This value can be changed each time flow values are learned as a method to accurately read and store flow rates for different stations representing different sprinkler types. Press to move to the next screen as shown. Note: If the intent is to use the Learn Flow function, the Mainline Break and No Flow delay values should not be longer than the Learn Delay value. This allows both Mainline Break and No Flow monitoring to function during Learning. Press g to change the value under the corresponding station from to LF. Press to move to the next station and repeat the process. If a station is assigned as a pump start, the corresponding station will be designated as shown below and this value will remain because it s been previously assigned. If not properly set, and the Learned Flow is less than 0.1 GPM, the value displayed will be 1.0 GPM. Set the delay period before the controller begins to record learned flow data, press until the following screen appears. urn the g or to increase or decrease the delay period HydroPoint Data Systems, Inc.

65 Learn Flow ; Learning and storing a single station or several stations flow data is a manual operation from the controller only. The controller will begin the Learn Flow immediately when On is selected. The controller will learn station flows in ascending numerical order up to max active stations, but only for the stations previously selected in Select Stations to Learn submenu. If additional stations are added at a later date or site conditions change, flow values can be re-learned at any time. Re-learned flow information will over-write previously collected and stored data. The test will last for the user-defined Mainline Break delay period previously selected. When the delay time expires, without any further mainline break detected, Learning will resume on the next configured station in ascending numerical order. An Alert will be raised on the station that faulted. The station will remain in the Stations to Learn screen so that the problem can be corrected and the station re-learned without having to reconfigure. Note: If the Learned Flow function is turned from On to Off, it will suspend this operation and retains any remaining stations previously selected to be learned. Learn Flow must be turned back On to resume this function. Note: No scheduled irrigation or manual irrigation should be operating during this operation to avoid collecting and storing incorrect data. Press until the following screen appears. In the example below, four stations have been selected to Learn Flow. The controller will operate each station manually until all stations selected have been collected and stored. If this sequence is stopped the controller will display the total number of stations remaining to learn as shown in the following example. Press g to change the underlined character from Off to On. The controller will immediately start irrigating the lowest number station selected and operate each station for a period of minutes previously selected under Delay Before Learning submenu. Note: If the Learn Flow is started while there is a Valve or Flow Alert on the master valve, the controller display will switch from On to Off. Learning will stop until the Alert is fixed and cleared. The stations previously selected to Learn Flow remain and this task can be resumed by reselecting On in the Learn Flow submenu. Pressing g from On to Off will immediately stop this command. If there is a Mainline Break (MB) during Learning, a Mainline Break test is performed to determine if there is a fault with master value. The display will change to the following: Note: When Learn Flow fails on a station, selected stations remain in the Learn Flow station list, so repairs can be made and the associated alert cleared. Note: During the Learned Flow sequence the following characters will appear in the lower right-hand corner of the screen. If any Alert exists, the characters will alternate between the display below and the word ALERT. Chapter 5 Flow Monitoring hydropoint.com

91 OR ET Everywhere has expired and customer does not wish to renew. When ET Everywhere service has expired, the controller will beep every 30 seconds notifying a user of a Subscription Alert. To stop the controller from beeping, reprogram all stations into User No ET mode, then call HydroPoint Customer Service ( ) to have your daily weather updates discontinued. The Controller Display is Blank The following steps may resolve this problem: Press SETUP. Press g or in either direction until a normal display is visible. If this does nothing, go to Step 3. Look for a yellow LED and a green LED on the right side of the left-hand input/output board. If both are lit, the problem is in the command module (front panel). If the green LED is not lit, the problem is in the power supply board. In either case, call Customer Service. Unable to View Flow Data There are several common reasons for this problem. Positive answers to the following questions will resolve this issue. Step 5: Is there a flow meter in use? If the answer is yes, follow steps 2-5. If the answer is no, press FLOW, press g once and confirm the Flow Meter Mode is Off. Is it compatible with our controllers? (Data Industrial IR-220 series and Creative Sensor Technology models are compatible.) Was the proper wire type used with proper waterproof connections? Is the controller configured to read your flow meter? Are the flow meter wires properly connected to the left-hand input/output board? (Currently, the second input/output board cannot read a flow meter.) See Chapter 3 for additional information. Mainline Break Alert with No Real Mainline Break The Mainline Break threshold may be set too low. The following steps may resolve the problem: View Learned Flow data in Station Flow screen in the PREVIEW menu to determine which station has the highest flow rate. Reset the Mainline Break Threshold to 20% higher than the highest possible station flow. This setting can be located in the FLOW menu. Set the Mainline Break Delay time long enough to allow mainline flow to stabilize before the controller checks for a Mainline Break. Clear the Mainline Break alert. See Chapter 3 for additional information. Broken Sprinkler or Broken Lateral Line Does not trigger an Alert The Station High Flow Offset Percentage may be set too high, or the excessive flow may be too small relative to normal station flow. The following steps may resolve this issue: Check the Station High Flow Offset Percentage. If it is too high, valid alerts will not be triggered. If it is too low, false alerts will be triggered due to fluctuations in mainline pressure. Reset the Station High Flow Offset Percentage to 20%. If mainline pressure is regulated, High Flow Offset can be lower. If the Offset Percentage is set low enough to catch every small overflow, some false alerts may occur. Step 5: Step 6: Step 7: Step 8: In lieu of the Station High Flow Offset, individual station high flow thresholds can be set for one or more stations independently of the global setting. Press FLOW menu. Press until the Station Flow display appears. Press g to change from Skip to Edit. Press to the first display in the submenu. Press until the specific station is located.

Users can also press the button on this screen to clear Alerts. Step 5: Step 6: If a program is running, the Flow Alert may reappear. If that happens, put Rain Pause on for 1 day to suspend irrigation. Repeat Steps 1 through 4. Remove the Rain Pause by setting it to zero days. See Chapter 2 for additional information. These are the three most common reasons for this issue: Possible Reason 1- The controller is learning station flows or is in the Shutdown mode: Check to see if LRNXX, (XX being the station number) or SHUTD is displayed in the lower right corner of the third line of the display. The display will alternately blink between either one of these during this task. Either of these functions will suspend scheduled irrigation. Only the station being learned will operate during LEARN FLOW. If placed in SHUTDOWN, no station will operate and a normally open master valve will be closed. To press off SHUTDOWN, press the OFF menu position. Press the button to cancel SHUTDOWN, then press Å or to RUN or another menu position. Step 5: Step 6: To cancel LEARN FLOW, press the FLOW menu position. Press to the right until LEARNING is displayed. Press g one click in either direction to press LEARN- ING Off. Possible Reason 2- The left-hand input/output board may not be receiving 24-volt power from the Power Supply board. Troubleshoot as follows: Check for a yellow LED and a green LED on the righthand side of the left-hand input/output board. If the yellow light is not lit, there is no 24-volt power for the station outputs. Call Customer Service. Possible Reason 3- There may be a common-wire problem. Troubleshoot as follows: Step 5: Press the HELP menu. Press until RUN VALVE TEST submenu appears. Use g to change the value from Skip to View. Use to view all active stations. If most stations show an NC (No Connect) alert, a common wire problem is indicated. Clear all Valve Alerts in the ALERTS menu and resolve the common wire problem.

See Chapter 4 for additional information. Runtimes shown in the Daily Station Report do not match runtimes projected in PREVIEW There are two factors that may account for this difference: These are as follows: 1. Logged runtime for any given day starts and stops at midnight. Stations running before midnight will be logged on the same day the program started. Stations running after midnight will be logged on the next day. Stations running through midnight will log part of their runtime on the programmed day and part on the next day. Check the runtime for both days to get total runtimes for each station. 2. The scheduling engine calculates runtimes based on the most current ET value available at the start of each program. This value may be different than the ET value that was current when runtimes were calculated for PREVIEW. The difference between the two values accounts for the difference between projected runtimes and logged runtimes. There are No LED s Illuminated on the Station Input/Output Board and No Display There are several possible causes for this problem. Follow these sequential steps to resolve this issue: Step 5: If the controller has a power cord, make sure it is plugged in. If the controller is powered from a circuit breaker, make sure it is turned on. If it is off, and if it immediately trips when reset, resolve the direct short problem before resetting again. Check the output from the transformer. It should be between 24VAC and 28VAC. If not, check for correct wiring. If still no output, replace the transformer. Check the fuse on the power supply board. If bad, resolve the short issue that caused the failure before installing a new 3.0 amp slow-blow fuse. Check the right-hand side of the input/output board for a yellow LED and a Green LED. If either is not lit, there is a power supply board problem. Call customer service HydroPoint Data Systems, Inc. All rights reserved. WTETP3OMv Chapter 7 Troubleshooting

94 Normally Open Master Valve Does Not Shut Down when a Mainline Break Occurs The following steps should resolve this issue: Check the SETUP menu to confirm the Master Valve is set to Normally Open. Check to be sure the master valve is connected to the MV terminal on the left-hand side input/output board. Run a valve test to make sure there is no SH or NC valve alert for the master valve. Physically check the master valve to be sure it is not a normally closed master valve that has been bled on or had the solenoid plunger removed to keep it open. A New Station Key Was Added but the New Stations Do Not Operate The following steps may resolve the problem: Check to be sure the blue LED on the station key is illuminated when connected. Check to be sure the station keys have been inserted from left to right starting on the left-hand 24-station input/output board. It generally takes the controller approximately 30 seconds to confirm a station key has been added. Check to be sure all the station keys are fully inserted. Check to be sure the new stations have been added to Max Active Stations in the SETUP menu. If they still do not function, call Customer Service. ET Display has a P After It In some cases this can be fixed by adjusting the screen contrast. Press ET. If you see a P after the ET value, the controller is currently running and an ET was communicated to the unit during station operation. The controller will label the ET as Pending until the irrigation schedule is complete. It will then apply the new ET to all programs for the next irrigation. Week 1 in the Review Screen is Much Different Days prior to installation will not be shown in the week 1 schedule. The controller shows what days have irrigated or it anticipates what days will irrigate if the weather remains as it is today. For example, if the controller is installed on a Friday, there will be no irrigation days shown prior to Friday in week 1. Press g to see irrigation day schedules for weeks 2 through 8. The irrigation days will display a pattern as you look at subsequent weeks. The Display in REVIEW Shows 99+ Minutes The runtime programmed is greater than 99 minutes. There are only two digits available in the display to show the runtime, so if the time actually exceeds 99 minutes, it shows 99+. This is a display issue only; the controller will irrigate for the full runtime. Controller Changes Sent Via the Web are not Reflected in the Controller (Two-way Communication Only) Minor program changes (Adjust or Station Mode) have been made on the Web site and are not observed in the controller. Press Å or to the ALERTS menu position and use g or until you can observe the COMMUNICATION STATUS.

Various plant species have different Kcs depending on the time of year. Typical Plant Type Species The WeatherTRAK series controller lists seventeen different plant types, fourteen with corresponding crop coefficients (Kc) and default root depths. The last three plant types can be assigned custom crop coefficients (Kc) for all twelve months for (Custom Plant A and B) or monthly custom crop coefficients for (Custom Turf). The names are simply placeholders. If a specific plant type with yearly or monthly data is known, enter the corresponding Kc and root zone depth accordingly. Plant type default root zone depths can be edited from a range of 2-36 in 1 increments. Shorter root depths will result in more frequent irrigation while deeper root depths may have runtime with multiple cycles and soak times and less frequent irrigation 2013 HydroPoint Data Systems, Inc.

99 Appendix B: Typical Soil Types Introduction This appendix is intended to provide a high-level overview of identifying and understanding existing site soil. Soil type is one of several variables that will ensure accurate application of water and plant health. What is the Significance of Understanding Soil Texture for Irrigation? Properly spaced sprinkler heads will discharge water in a measureable value called precipitation rate or the amount of water applied in inches per hour. Different sprinkler types have different precipitation rates that may not always be matched to the soils infiltration rate or ability to absorb water. Applying water too fast in a sandy soil could drive the water past the root zone where supplemental irrigation is ineffective. The same principle of applying water too fast in a clay soil with a slow infiltration rate may cause irrigation run-off and waste water. Identifying the soil type as part of site and environmental elements with your WeatherTRAK controller will enable the controller to integrate soil and irrigation science. When entered into the controller it will automatically determine the number of irrigation cycles and periods or soak-time between cycles. The purpose of multiple cycle and soak times is to hold water in the selected root zone depth or (default value if satisfactory) for the corresponding plant type. This root depth setting can be slowly increased as plants established and plant maturity increases. Most western soils are commonly a mixture of clay loam, or sandy clay, and are not strictly clay. Its important to recognize that plant intake of water and nutrients is somewhat difficult in clay soils due to the electrical charge between water and a clay soil particle. The controller may appear to over-irrigate when it s actually maintaining sufficient water in the root zone depth for this soil-plant interaction to take place. USDA Definitions of Soil Textures Soils are comprised of particles with a wide variety of shapes and sizes. Depending on their size and individual mineral particles, soils are divided into three major categories: Sand Silt Clay The U.S. Department of Agriculture developed a system of soil classification based on various particles sizes to define soil texture or the relative proportions of sand, silt and clay found in a particular soil sample. Overall, there are twelve recognized soil textural classifications based on the particle size (see Tables 1 and 2). Of these twelve, five are commonly used for agronomic applications. These are the same five categories found in the choices on WeatherTRAK controllers identified as: Sandy Sandy Loam Loam Clay Loam Clay 2013 HydroPoint Data Systems, Inc. All rights reserved. WTETP3OMv1.1 B.i Appendix B Typical Soil Types

100 Soil Texture Water Holding Capability Infiltration / Permeability Expected Contoller Behavior Sandy Low High Frequent watering, longer runtimes Sandy Loam Low to Medium Medium to High Longer periods between watering than sandy soils, but shorter runtimes Loam Medium Medium Periodic watering, potentially the shortest run times, but some cycle and soaks expected Clay Loam Medium to High Low to Medium Periodic watering with longer runtimes than clay but fewer cycle and soak times Clay High Low Potential frequent watering, short runtimes, multiple cycle/soaks These classifications are determined by the percentages of soil particles that can pass through various sieve sizes. The percentage of particle sizes can impact soil-plant interactions particularly water holding/retention and infiltration/percolation properties. The following table identifies general guidelines of soil texture, water holding capability, permeability and expected controller behavior. Determining Soil Type There are a number of field methods that can be used to quickly place your soil type in one of the three major soil texture classifications. The enclosed web link provides a step-by-step methodology of quickly determining soil texture in the field. gsfc.nasa.gov/tbf/tbfguide.htm For greater accuracy, detailed information and less reliance on in-field techniques, collect a large coffee can sample and contact your local Farm Advisor s office for the nearest soil lab. The Table 1 below depicts the recognized soil size separates used to classify a particular soil. Table 2 is a soil texture classification chart depicting soil particle size percentages and soil texture classifications. Name of Separate Diameter (Range) (Sieve size in mm) Very Coarse Sand Coarse Sand Medium Sand Fine Sand Very Fine Sand Silt Clay Below Table 1 U.S. Department of Agriculture Size Limits of Soil Separates Other physical properties such as mineral content can also determine a plant s ability to absorb and hold onto existing soil nutrients or additives from supplemental fertilization. Smaller particle sized soils such as clay, tend to absorb water slower than larger particle sizes such as sand. Soil absorption rates will also impact the number of irrigation cycles and soak times between cycles and prevent run-off or water traveling below the root zone where plant intake is ineffective. The three major categories of soil texture represent different particle shapes. For example, a sand particle tends to be quite angular and has a fairly large particle size compared to a clay soil particle. The shape and electrical charge of a sand soil particle also results in a porous soil and tends to be fast draining that can quickly pass water and nutrients below root zones where they cannot be absorbed. Sandy soils also do not commonly compact as well as smaller more tightly shaped soil particles such as loam or clay. Clay soil typically represents the smallest particle size and also has the strongest electrical charge. Clay soil holds the soil particles tightly together slowing infiltration rates and water availability to plants.

101 Appendix C: Soil Depletion Model Introduction The ET Pro3 series and other WeatherTRAK-enabled control products incorporate a soil depletion model that was developed by universities and is recognized by the Irrigation Association (IA). The graphic below (see Figure C.1) depicts some of the site variables that can impact depletion of water through evapotranspiration, soil infiltration rates and water holding properties, runoff and root depths. Managing these and other variables determines how often to irrigate and how much irrigation to apply. See Figure C.2 which depicts how the depletion model works. Figure C.2 Depletion Model The net goal is to apply only the required amount of water to maintain plant health. The following paragraphs are intended to demonstrate how WeatherTRAK-enabled controllers incorporate a depletion model as a water management tool. Definitions To better understand some of the terminology used in this document, several definitions have been provided as follows: Evapotranspiration or ET is unit of measure of how much water transpires from a plant and evaporates from the soil in inches per day, week or month. Variables used to properly calculate ET are solar radiation, temperature, wind, and dew point. ET is commonly listed as a daily or weekly value. For example if a weekly ET of 1.00 is identified, an average daily ET would be 1/7th of this value or Figure C.1 Depletion Variables Soil Moisture Depletion or just Depletion is commonly identified in a percentage. In very simple terms, plants require cycles of irrigation for exchange of water and nutrients followed by a dry-out period before the next application of water. Some plant species are more tolerant to longer dry-out periods than others. For most landscape applications, the percentage of allowable depletion is commonly 50%. The Irrigation Association recognizes 50% as the percentage used in their Best Management Practices for determining irrigation run times and frequency HydroPoint Data Systems, Inc.

102 MAD has been defined in different ways in the irrigation industry as (1) management allowed depletion, and (2) maximum allowed depletion. Management allowed depletion is the percentage of total plant available water (PAW) that is to be depleted from the active root zone before irrigation is applied. This amount is managed by a water manager to vary the amount of water depleted from the root zone between irrigation, and thus varies the amount of stress that the plant undergoes. Maximum allowed depletion is the maximum amount of depletion that can occur without stress to the plant. The setting of both types of MAD is dependent on the type of plant and soil. In this document, the "maximum allowed depletion" definition is used. Plant Available Water (PAW) is the amount of water available to the plant in its root zone. This varies based on the soil type and plant root depth. The relationship between soil type and available water is important is maintaining optimum plant health. Target MAD is a feature in the ET Pro3 series that allows a user to increase or decrease the frequency of irrigation by changing the default depletion value of 50% in 5% increments. This function can be applied on a station by station basis providing greater flexibility in managing the soil/water balance, particularly in landscapes where native or indigenous plant material is used. Soil / Water Relationship The ET Pro3 series usually uses 50% as the MAD in its depletion model. This simply means, before half of the available water in the root zone is depleted (evaporated, transpired or has traveled outside of the root zone) supplemental irrigation is added to refill the reservoir. Allowing the depletion amount to drop below 50% can lead to plant stress for some plant material and once a plant has reached permanent wilting point (PWP), no amount of water can revive the plant. Example #1 In this example, the landscape variables are as follows: No. Site or Landscape Attribute 1 Sprinkler Type Fixed Spray Head 2 Precip Rate 1.80" / hr. 3 Sprinkler Efficiency 55% 4 Soil Type Clay Loam 5 Plant Type Cool Season Turf 6 Root Zone Depth 4" 7 Plant Kc Microclimate Sunny All day 9 Available Water 1.65" Daily ET is 0.15 for 3 days in a row. The graphic below illustrates how each day after irrigation is applied, available water transpires/ evaporates and infiltrates deeper into the soil through gravity and soil properties. Each day the controller determines how much depletion has occurred to determine the next scheduled irrigation application. Day. Daily ET Plant Kc ETc ET x KC Daily Depletion Status " % No Irrigation " % Irrigation Scheduled % % Depletion would have exceeded MAD of 50% The Available Water (AW) for the soil type selected is 1.65 inches is drawn down over a three day period based on a daily ET of 0.15 inches. After the second day, the soil reservoir is 34% depleted. By the third day the soil reservoir would be 51% depleted which exceeds the 50% MAD threshold, so irrigation is applied on Day 2, to avoid deficit irrigation by the third day. The table below is intended to demonstrate how available soil water is depleted each day. WeatherTRAK-enabled products apply this model to each station independently. The following two examples have been developed to demonstrate how different landscape variables can dictate different run times and days between irrigation with the same daily ET. Both examples incorporate a 50% depletion value as the benchmark of when to irrigate. Appendix C Soil Depletion Model C.ii hydropoint.com

Root zone depth and daily ET are additional variables that will determine when and how much irrigation is applied. Applying water before it s required can promote shallow root systems and wasted water. Frequent watering will push available water down below the root zone where it cannot be effectively absorbed by a plant. Figure C.3 dipicts the impacts of both types of watering practice. Daily ET is 0.15 for 8 days in a row. The Allowable Water (AW) of 1.3 inches and a Crop Coefficient (Kc) of Again the daily ET is 0.15 and after eight days time, the water reservoir has been depleted by nearly 50% requiring irrigation because by the ninth day the 50% MAD value would have been exceeded.

104 The net result is the ET Pro3 series controller applies irrigation and soil science to automatically determine the proper run time based on these site and environmental differences. Example #1 Watering Schedule ST01 A 07.8 MIN 02X AUTO WK1: SMTWTFS +00% Soak 10 WK2: SMTWTFS Example #2 Watering Schedule ST01 A 08.6 MIN 01X AUTO WK1: SMTWTFS +00% Soak 5 WK2: SMTWTFS As weather changes (ET increasing or decreasing), the amount of water and the frequency of water being applied will vary as depletion increases or decreases. To properly address daily weather changes using a conventional controller would require multiple calculations for each station, then physically adjusting the irrigation schedule every day. By contrast WeatherTRAK incorporates weather changes and automatically adjusts station run times and frequency to achieve optimal plant health while maximizing water savings.
