Transcription

1 Product Bulletin TE-7700 Series Issue Date November 15, 2002 TE-7700 Series Radio Frequency (RF) Wireless Room Temperature Sensing System The Sensing System consists of a TE-7710 Series RF Wireless Temperature and Set Point, and a TE-7720 Series RF Receiver. Together, these components monitor the temperature set point and actual temperature of a single conditioned zone, and transmit this data to the receiver at predefined intervals. The information is translated into a control signal that works directly with Johnson Controls VMA1400 Series Controllers in Heating, Ventilating, and Air Conditioning (HVAC) systems. The Sensing System uses 900 MHz spread-spectrum technology to prevent accidental and unauthorized interference, and to provide better propagation characteristics within the building. Field-addressable DIP switches establish a unique, secure address between each transmitter and receiver. This one-to-one control approach enhances reliability by reducing susceptibility to signal interference and preventing a single point of failure in multiple zone applications. To optimize comfort in larger zones, a single receiver can average the measured temperature of up to four transmitters in the zone, or select the highest or lowest measured temperature of the zone. Optional signal strength site survey tools are available to determine the appropriate location of the RF wireless temperature sensing system, prior to its installation. These tools verify that the RF signal strength is sufficient to ensure proper operation.

5 System Operation The Sensing System is designed to work directly with Johnson Controls VMA1400 Series Controllers in HVAC systems, to monitor the temperature of a single conditioned zone within a building. This RF system consists of a wireless TE-7710 Series Temperature and Set Point, and a TE-7720 Series Receiver. Figure 5 illustrates the relationship between the TE-7710 Series, the TE-7720 Series Receiver, and the VMA1400 Series Controller. Due to the 900 MHz operating frequency of the Sensing System, this product is acceptable for use in the United States, Canada, Mexico, Australia, New Zealand, and throughout South America. The battery-operated transmitter of the Sensing System communicates the temperature set point and actual temperature of the zone to the receiver approximately every 60 seconds. These 60-second transmission intervals provide optimal HVAC control, while conserving battery life. The transmitted information is combined with a unique, secure, DIP switch selectable address and other supporting data prior to transmission. To optimize comfort in larger zones, a single receiver can average the measured temperature of up to four transmitters in the zone, or select the highest or lowest measured temperature of the zone. A receiver with the same address as the transmitter receives the information and converts the data into the appropriate units and electrical format to be understood by the VMA1400 Series Controller. The information also includes diagnostic data, such as field strength measurements and transmission number, to help with commissioning and site evaluation. This information also indicates the battery condition to warn supervisory equipment when the battery needs to be replaced. The receiver features two LEDs that verify proper signal strength and zone bus communication. A three-level RF signal-to-noise ratio LED verifies adequate RF signal strength and minimizes the need for pre-installation signal strength measurements using a site survey tool. Note: A solid illumination of the three-level RF signal-to-noise ratio LED indicates that the TE-7720 Series RF Receiver has power and is ready for operation. Transmission intervals occur approximately every 60 seconds, with three-level LED indication occurring immediately after every transmission. A second LED for zone bus activity provides direct, visual indication of communication between the receiver and the VMA1400 Series Controller. A manual override pushbutton allows the occupant to control the temperature of a zone by overriding time-of-day scheduling. This feature allows the end user to signal the receiver that the space is occupied after normal business hours or on weekends. Optional signal strength site survey tools are available to determine the appropriate location of the Sensing System prior to its installation. These site survey tools verify that the RF transmission signal is sufficient to ensure proper system operation. Refer to the Signal Strength Site Survey Tools section for more details. Recommended Applications Using the mounting hardware included with each component, the TE-7700 Series RF Wireless Temperature Sensing System is ideal for installations where building aesthetics would normally hinder hardwiring. Recommended applications for this RF wireless system are numerous and include the following: museums, historical buildings, atriums, or other sites where building retention and its historical preservation are important office buildings, university campuses, educational facilities, and other structures that incorporate brick or solid concrete walls and/or ceilings buildings featuring marble, granite, glass, mirrored, wood veneer, or other decorative surfaces that present significant challenges when attempting hardwiring office buildings, retail stores, and other commercial real estate where tenant turnover is frequent and temporary walls and ceilings are common stadiums, arenas, gymnasiums, convention centers, airports, zoos, and other locations that feature large, open spaces buildings containing asbestos walls or other biohazard materials that cannot be disturbed TE-7700 Series Radio Frequency (RF) Wireless Room Temperature Sensing System Product Bulletin 5

7 Benefits of Wireless Transmission vs. Hardwired Counterparts The radio frequency design of the TE-7700 Series RF Wireless Temperature Sensing System improves application flexibility by providing an alternative to hardwired room temperature sensing counterparts. This temperature sensing system allows for fast, economical, and low-maintenance installation since its components are installed quickly and easily, reducing installation time and associated costs. Ideal for retrofit applications, the TE-7710 Series RF Wireless Temperature and Set Point can be easily relocated after initial installation, providing added flexibility. Advantages of 900 MHz Direct-Sequence, Spread-Spectrum RF Technology for One-to-One Control The Sensing System uses 900 MHz direct-sequence, spread-spectrum RF technology to transmit data regarding a conditioned zone within a building. This transmitted information is translated into a control signal that works directly with Johnson Controls VMA1400 Series Controllers in HVAC systems. Direct-Sequence Transmission vs. Frequency-Hopping Transmission Direct sequence and frequency hopping are both forms of spread-spectrum RF transmission. Direct-sequence transmission requires much less overall power than frequency-hopping transmission, since direct-sequence transmitters are on for a shorter period of time. As a result, the transmitter battery life is extended. Consequently, direct-sequence transmission is the spread-spectrum RF transmission of choice for battery-operated wireless room temperature sensing systems. Spread-Spectrum Technology vs. Narrow-Band Technology The concept of spread-spectrum technology involves the transmitter systematically spreading the RF transmitted data out over a broad frequency range. Unlike narrow-band technology, the bandwidth of the spread-spectrum transmitted RF signal is much greater than the bandwidth of the original message. The bandwidth of the spread-spectrum transmitted RF signal is determined by a spreading code that is independent of the original transmitted message, and is known only by the transmitter and the receiver. The receiver de-spreads the transmitted RF signal and reads the data that is being communicated from the transmitter. Receivers that do not have the same spreading code as the transmitter cannot de-spread the transmitted RF signal, and simply see the signal as irrelevant background transmissions. Spreading and de-spreading the transmitted RF signal enhances the security of the TE-7700 Series RF Wireless Room Temperature Sensing System since, unlike narrow-band technology, spread-spectrum technology provides a broad range of frequencies that make it very difficult to jam. Spreading and de-spreading the transmitted RF signal also augments the ability of the TE-7700 Series RF Wireless Room Temperature Sensing System to operate in the same environment as other technologies using the same frequency band. One-to-One Control vs. Many-to-One Control The Sensing System uses a one-to-one control approach to monitor the temperature of a single conditioned zone within a building. In a one-to-one control arrangement, each zone has its own receiver and transmitter (or multiple transmitters for temperature averaging and high/low selection applications) working directly with a single VMA1400 Series Controller. One-to-one control offers the following advantages in HVAC systems: The control loop timing is not impacted (as is the case with systems where the transmitted data is routed through a central processor or network controller), resulting in better HVAC control. Since transmitted information is not routed through a central processor or network controller (as is the case with a many-to-one control arrangement), a single point of failure in multiple zone applications is avoided. Personnel inexperienced in digital communications can easily install and operate this RF temperature sensing system, since the only addressing required between the transmitter and its receiver is accomplished through simple DIP switch settings. Since the receiver is located in the same zone as the transmitter, an inherently shorter transmission range results. This shorter transmission range produces a high signal-to-noise ratio that reduces susceptibility to signal interference. Even large increases in irrelevant background transmissions (due to other transmitters or equipment) are highly unlikely to interfere with signal transmission.

8 Effects of Cellular and Cordless Phone Transmissions The Sensing System operates on a spread-spectrum frequency between 902 MHz and 928 MHz. Conversely, cellular phones operate on a spread-spectrum frequency between 810 MHz and 890 MHz, while cordless phones use a narrow band with current technology migrating toward a frequency of 2.4 GHz. Consequently, there is negligible interference between cellular and cordless phone transmissions and the transmission signals from the Sensing System. Mounting Methods Hardware is included with each component of the Sensing System, allowing for a variety of mounting scenarios. The preferred mounting method for the transmitter uses the two expandable wall anchors included with the unit. Double-sided adhesive foam tape is also provided with each transmitter for installations where building retention and its historical preservation are important, or in buildings featuring marble, granite, glass, mirrored, wood veneer, or other decorative surfaces. The receiver may be mounted using the four No. 6 sheet metal screws included with the unit. Component Quantities for System Control Refer to the following guidelines when applying the Sensing System: Assign one DIP switch dedicated transmitter per receiver for standard RF wireless installations in smaller zones. Assign up to four transmitters (with the same DIP switch address) per receiver for multiple transmitter temperature averaging applications in larger zones. Assign up to four transmitters (with the same DIP switch address) per receiver for high/low measured temperature selection applications in larger zones. Allow one receiver for every VMA1400 Series Controller. Install up to 510 receivers in a single transmission field. Location Considerations Refer to the following guidelines when selecting a mounting location for the TE-7710 Series RF Wireless Temperature and Set Point : Locate the transmitter so that it is easily accessible. Locate the transmitter on the same floor, or one floor above or one floor below the receiver. Locate the transmitter on an inside wall away from water pipes and air ducts, minimally 54 in. (1.4 m) above the floor level, in an area that accurately represents the temperature of the controlled space. If possible, locate the transmitter in the line of sight with the receiver, to minimize signal transmission loss. Check that there are no metal objects (including equipment rooms and elevator shafts) blocking the RF transmission signal from the transmitter to the receiver. Do not mount the transmitter in recessed areas, in shelving units or metal enclosures, or behind curtains or doors. Do not mount the transmitter in areas that are exposed to direct sunlight or condensation, or in areas that are in close proximity to various heat sources. Do not mount the transmitter in areas susceptible to warm or cool drafts such as lobbies, walkways, or near a bank of computers. Do not mount the transmitter less than 2 ft (0.6 m) from the receiver. The distance between two or more transmitter mounting locations is irrelevant. Receiver Location Considerations Refer to the following guidelines when selecting a mounting location for the TE-7720 Series RF Receiver: Locate the receiver so that it is easily accessible and within close proximity to the VMA1400 Series Controller, using the 6 ft (1.8 m) power and zone bus cable included with the unit. If needed, communication cables to connect the zone bus only (no power) measuring 25 ft (7.6 m), 50 ft (15.2 m), 75 ft (22.9 m), and 100 ft (30.5 m) are available; refer to Table 2 for more details. 8 TE-7700 Series Radio Frequency (RF) Wireless Room Temperature Sensing System Product Bulletin

9 Locate the receiver on the same floor, or one floor above, or one floor below the transmitter. If possible, locate the receiver in the line of sight with the transmitter, to minimize signal transmission loss. Check that there are no metal objects (including equipment rooms and elevator shafts) blocking the RF transmission signal from the transmitter to the receiver. Mount the receiver in any orientation, on any flat surface, with the face of the receiver pointing in the general direction of the transmitter. If the transmitted RF signal is weak, try rotating the receiver in 90 increments, selecting a different mounting plane, or selecting a new mounting location. Do not mount the receiver in recessed areas or in shelving units or metal enclosures. Do not mount the receiver less than 2 ft (0.6 m) from the transmitter. Do not mount the receiver less than 3 ft (0.9 m) from another receiver. RF Transmission Range Most studies related to RF transmission recommend that a signal strength site survey be conducted prior to installing a temperature sensing system in a building. The intention of this survey is to determine in advance the strength of the transmitted RF signal, taking into consideration the surrounding site characteristics to ensure success of the RF transmission. The Sensing System incorporates a number of design features that eliminate most transmission problems and minimize the need for a signal strength site survey tool. The one-to-one control approach of the Sensing System inherently minimizes the distance between the transmitter and its associated receiver, eliminating the need for repeaters. The receiver used with the TE-7700 Series RF Wireless Room Temperature Sensing System provides three-level LED indication of the RF signal-to-noise ratio, which is the most important measure of signal strength and margin: - Three consecutive blinks of the LED indicate an excellent signal strength. - Two consecutive blinks of the LED indicate a good signal strength. - One blink of the LED indicates a weak signal strength. A weak signal strength may result in sporadic loss of data; therefore, the transmitter and/or receiver mounting locations should be reconsidered. Refer to the Location Considerations and the Receiver Location Considerations sections for more details. Note: A solid illumination of the three-level RF signal-to-noise ratio LED indicates that the TE-7720 Series RF Receiver has power and is ready for operation. Transmission intervals occur approximately every 60 seconds, with three-level LED indication occurring immediately after every transmission. A transmission may also be activated by depressing the manual override pushbutton on the TE-7710 Series RF Wireless, and watching for LED indication at the receiver. In most temperature sensing systems, the receiver and the controller are located within a close proximity of each other. If necessary, the receiver may be located up to 300 ft (91.4 m) from the VMA1400 Series Controller, in order to optimize reception of the radio frequency transmission in Sensing Systems. This feature provides effective operation of the control system in locations where large metal objects (such as those found in elevator shafts and HVAC equipment rooms) might interrupt the RF transmission signal. The radio frequency transmission range for the Sensing System is specified at 1 mile or 5,280 ft (1,609.3 m) maximum in open air locations and 1,000 ft (304.8 m) maximum for indoor line-of-sight locations. Taking into consideration absorption and reflection due to metal objects, walls, and furniture typically found in today s building environments, a more practical average RF transmission range would be 200 ft (61 m), provided that no large metal objects interrupt the line of sight between the transmitter and its corresponding receiver. TE-7700 Series Radio Frequency (RF) Wireless Room Temperature Sensing System Product Bulletin 9

10 In the majority of RF wireless installations, the transmitter is typically located in the zone being controlled, and its associated receiver is typically mounted next to the VMA1400 Series Controller. As a result, the transmission range required is only about 50 ft (15.2 m). This relatively short transmission range results in a very high signal-to-noise ratio the primary measure of data transmission reliability in RF wireless systems. Consequently, even large increases in irrelevant background transmissions (due to other transmitters or equipment) are highly unlikely to interfere with signal transmission. Note: While the radio frequency transmission signal of the TE-7700 Series RF Wireless Room Temperature Sensing System can penetrate most types of flooring, the strength of the signal is dependent upon the materials of construction. Steel pans used during construction to support concrete floors while they are setting will likely interfere with RF transmission. Concrete floors that are reinforced with metal rebar typically will allow RF transmission through at least one vertical level, with limited horizontal range. When in doubt, use the three-level LED indication of signal strength and margin to guide the installation. Signal Strength Site Survey Tools Johnson Controls offers 5-second interval, fast-update site survey tools for use in new and retrofit installations, to help determine the appropriate mounting location for the TE-7700 Series RF Wireless Room Temperature Sensing System. The TE Signal Strength Site Survey Tool and the TE Receiver Signal Strength Site Survey Tool function together to determine the strength of the RF transmission signal between the intended mounting locations of the transmitter and receiver. The TE Receiver Signal Strength Site Survey Tool provides three-level LED indication of the RF signal-to-noise ratio: Three consecutive blinks of the LED indicate an excellent signal strength. Two consecutive blinks of the LED indicate a good signal strength. One blink of the LED indicates a weak signal strength. A weak signal strength may result in sporadic loss of data; therefore, the transmitter and/or receiver mounting locations should be reconsidered. Refer to the Location Considerations and the Receiver Location Considerations sections for more details. Both signal strength site survey tools are battery operated, with transmission intervals of approximately every 5 seconds. The TE includes one 3.0-volt lithium cell, while the TE includes three 3.0-volt lithium cells. Replacement batteries must be purchased locally; suitable models include Duracell Ultra 123, Panasonic CR123A, Toshiba CR123A, GE/Sanyo CR123A, or the equivalent. Battery Life and Low Battery Indication The battery life of the 3.0-volt lithium cell included with each TE-7710 Series RF Wireless Temperature and Set Point is typically 36 months (24 months minimum). The transmitter communicates diagnostic data including battery condition approximately every 60 seconds to the TE-7720 Series RF Receiver, where it is converted into the appropriate units and electrical format to warn supervisory equipment (via the VMA1400 Series Controller) when the battery needs to be replaced. Replacement batteries must be purchased locally; suitable models include Duracell Ultra 123, Panasonic CR123A, Toshiba CR123A, GE/Sanyo CR123A, or the equivalent.
