Control Functions The compact controller TCY operates with four different control modules. These modules can be activated and parameterized according to the application to be controlled. The main modules are: Temperature PI, Temperature On/Off, Universal PI and Universal On/Off. All modules operate simultaneously. In order to use the controller, at least one control module must be enabled. The outputs that respond to each control loop need to be assigned in the output section. Temperature Control Module HC -00: 2-pipe or 4-pipe system. Select 2-pipe system if the system has only a single coil that operates as heater in winter and cooling device in summer. Select 4-pipe system, if specific heating and cooling coils are available. HC -01: Dead Zone Span. The cooling setpoint W C consists of the heating setpoint and the dead zone span. Changing the cooling setpoint in 2-pipe mode therefore changes as well the heating setpoint. The factory setting for the dead zone span is 1K. Modulating PI-Control The temperature PI control mode is enabled with parameter HC-02. The controller maintains the temperature set point by calculating the output position based on proven PI control algorithms. Control parameters: HC -03, HC-04: P-bands for heating and cooling are programmable. The factory setting is 2 K. The p-bands are disabled if 0 is selected. HC -05: A large I part increases the swinging tendency of the control loop. Limiting the integral part may reduce this tendency. The I-part is disabled if 0 is selected. HC -06: Tn, Reset time of Analog loop integral. Tn is the time needed for the integral to run from 0 to 100%. The range is 0.5 30 min. The setting depends on the control application. For temperature control of a medium sized room, a setting of 5-10 minutes is appropriate. For pressure control on a VAV box a value of 3 minutes is recommended, depending on the speed of the actuator.

On/Off control is suitable to operate fan coil valves and reheat or cooling compressor stages. By providing the dry Normally Open contact, any voltage from 10 250V for actuators and switching stages may be used. Switching power is limited to 0.5A per stage. Control parameters: W H X DZ W C X PC T [K] HC -08: Enables a second stage for reheat. HC-09: Enables a second compressor stage for cooling. HC -10, HC-11: The switching span determines the temperature difference required for the next heating stage to be activated. HC -12: The hysteresis defines when a heating stage is switched off. The aim is to avoid unnecessary switching of heating stages thus increasing the life span of involved equipment as well as saving energy. Delayed switching. The upper heating/ cooling stages will not switch on at the same time. The higher stage will not start earlier than 5 seconds after the lower stage has been initiated. 0 Tn t [min] On/off Control Stage 2 Heating Cooling Stage 1 0 W H W C T [K] H RC X RC X DZ H RC Hysteresis Heating/Cooling X RC Switching Span Heating/Cooling Version: 2004-07 info@vectorcontrols.com Page 2/12

Universal Control Mode Cascade control Instead of using a setpoint as the control target, we can use the output of the temperature control loop as setpoint. This is for example used for VAV controllers. Enable 1U-00 to activate cascade control. Universal Control Mode: PI-Control 1U-02, 1U-03 = Enable reverse and direct operation. The controller reads the selected input value, and maintains it by calculating the appropriate output signal. The control function used is PI control. Control parameters: 1U-01 Dead Zone Span for Universal Loop 1. The direct acting setpoint w D consists of the reverse acting setpoint and the dead zone span. The factory setting for the dead zone span is 0. 1U-04: Direct acting P-band. Range depends on the selection of the input. Selecting 0 disables the P part. 1U-05: Reverse acting P-band. Range depends on the selection of the input. Selecting 0 disables the P part. 1U-06: Maximum limit of I-part: A large I part increases the swinging tendency of the control loop. Limiting the integral part may reduce this tendency. The I-part is disabled if 0 is selected. 1U-07: Reset time of integral: Tn is the time needed for the integral to run from 0 to 100%. The range is 0.5 30 min. The setting depends on the application and the actuators involved. It should be at least 1.2 times the reaction time of the control cycle.

It is possible to use an external sensor of the same kind by connecting it to the two terminal connectors. Specified accuracy can only be guaranteed by using a manufacturer approved temperature sensor. Contact your dealer for details. The active sensor needs to be selected by setting a slide switch, which is located at the back of the operation terminal. Version: 2004-07 info@vectorcontrols.com Page 3/12

Analog Inputs: The analog input signals may be configured with jumpers to 0-10V, 0-5V and 4-20 ma. The jumpers are located just behind the terminal connector of each input. The drawings below indicate the jumper placement for each signal type. The factory setting is 0-10 VDC. The range of the input signal can be specified in software by setting a minimum and a maximum limit. The limits are in percent of the full range The display value of the input signal may be specified. For example a pressure sensor has a 4-20 ma output and a pressure range of 0 200 Pa. It is possible to transform the Signal Type 0 10 VDC 0 5 VDC 0 20 ma DC Jumper selection (1-4) (3-4) (2-3) input signal into a different dimension by setting the minimum and maximum transformation value in the input configuration setup. In our example the display will read 100 for a 12 ma signal. Averaging function: Some sensor signals (for example air flow sensors) tend to fluctuate. The controller measures every second the signal inputs. Select how many values should be used to calculate the averaging signal, which will be used as control input. (Too many samples for an averaging signal may increase the swinging te ndency, increase reset time on PI signals in this case) Output Configuration Analog Output The analog output may be configured with jumpers for 0-10 VDC or 0-20 ma control signals. The jumpers are located behind the terminal connector of the respective analog output. See table below for jumper placement. The factory setting is to 0-10 VDC. The signal range is specified in software by setting a minimum and a maximum limit. Each output may be assigned to a control loop, set to manual or serve as a temperature feedback of the internal temperature sensor. See parameter OP section for details: Enabling OP-03 changes DO1 and DO1 into a floating output for a PI loop. In this case the running time of the actuator needs to be specified. Running time is defined as the time required for the actuator to run from fully open to fully closed or vise versa. Note that it is recommended to use only actuators with a fixed running time. Once fully open or fully closed the running time for the actuator is extended for 5 minutes. If OP-03 is in the OFF position, DO1 and DO2 may be used as switching outputs for an /OFF control module. Digital Outputs Signal Type 0 10 VDC (1-2) 0 20 ma DC (2-3) The switching outputs DO1 and DO2 are factory assigned as floating output. They may be assigned as digital outputs using OP-07 to OP-08. The digital outputs may be used either as switching outputs for Temperature or Universal /OFF modules. Each output needs to be assigned to a control loop. See parameter OP section for details. Time schedule on digital outputs The digital outputs may be used with an individual schedule. Select option 7 at the OP7/8 parameter. There are two programs with each 4 switching times available. Program 4 and 5 applies for DO1 and Program 6 and 7 for DO2. Schedule for Digital outputs will only operate if floating output is disabled (OP03 = OFF). Jumper selection Switching difference on floating output The controller moves the actuator to the calculated position by either opening or closing the actuator. The actuator should not be moved for every little change in position, since this would reduce the lifetime of the actuator. OP-06: Switching difference: The actuator will only move, if the difference to the current actuator position is larger than this parameter. Power Failure All the parameters and set points are memorized and don t need to be reentered. Depending on UP04 the unit will remain switched off, switch on automatically or return to the operation mode it was in before the power failure. Deluxe version only: Timer operation and daytime setting will be retained. (Battery factory mounted battery life is 2 years). Frost Protection The controller will enter frost protection mode if the room temperature drops below 5 C (41 F). All heating outputs will be fully opened. Frost protection mode will be left once the temperature reaches 10 C (50 F). Frost protection display will remain until a button is pressed. Frost protection can be enabled/disabled using user parameter UP-06. Note: Frost protection uses the NTC temperature input. Analog sensors set as temperature sensor with 1U11 will not be able to trigger frost protection Clock Operation (Deluxe Version) TLCY contains a battery backed quartz clock. Up to 16 mode changes (STANDBY, COMFORT, OFF) based on weekdays and time may be programmed. See chapter operation on how to program and assign switch times to the corresponding loops. A blinking clock indicates that the battery is empty and needs to be replaced. The time needs to be set in order to allow time programs to operate. See chapter operation, advanced settings for instructions on how to set the time. Version: 2004-07 info@vectorcontrols.com Page 4/12
