Applications Air Only Systems: Constant or Variable Air Volume systems for single or dual duct systems with options of:

o up to two reheat stages o supply air, extract air cascade control o humidity control o Control for variable speed fans

Air/Water Systems:

o Fan Coil units for 2-pipe or 4-pipe systems with options of: Humidity control Pressure control

o radiator control, chilled ceiling

Water Only Systems: Radiator, floor heating or chilled ceilings

Individual room control for hotel rooms, meeting rooms, etc. General Description The TCY3 is a stand-alone electronic universal controller with two autonomous control loops. Each control loop may use up to 2 PID sequences and 6 binary sequences. The TCY3-T0121R features 1 NTC temperature sensor and 1 analog input, 2 binary outputs and one analog output. The outputs need to be assigned to the control sequences by parameters. A detailed configuration is possible by following a simple setup routine. The TCY3 can be configured using the standard operation terminal. No special tool or software is required.

Selection of actuators and sensors

Temperature Sensors: Use only our approved NTC sensors to achieve maximum accuracy. Recommended is SDB-Tn10-20 as Duct sensor, SRA-Tn10 as Room sensor and SDB-Tn10-20 with AMI-S10 as immersion sensor.

Modulating Actuators: Choose actuators with an input signal type of 0-10 V DC or 4-20 mA. Minimum and maximum signal limitations may be set in software.

Floating Actuators: Actuators with constant running time are recommended. Observe power limits on binary devices.

Binary auxiliary devices: E.g. pumps, fans, on/off valves, humidifiers, etc. Do not directly connect devices that exceed 48 VAC, 2(1.2) A. Observe startup current on inductive loads.
