The WTS Series Touch Button thermostat is a temperature control device with an extra-large LCD display, capacitive touch interface with color icons and manual or automatic fan speed selection.
The units monitor the actual room temperature, humidity* and the set temperature in real-time to control the opening / closing of the valves in the fan coil units to regulate the room temperature to the occupant's desired comfort. Chose from a variety of options including white or black color shell, humidity display, Modbus communications and ECM fan support. Its ultra-thin design fits any standard 86 x 86mm or smaller wall-mounted installation box. It features built-in temperature and humidity* sensor, anti-freeze protection, lock/unlock operating buttons and timed shutdown function.
FEATURES AND BENEFITS
•Built-in temperature and humidity* sensor. The unit monitors in real-time the actual room temperature and the set temperature to regulate the room temperature by controlling the opening/closing of the fan coil unit valve and the fan speed.
•Extra-large LCD andintuitive interfacemaking it easy to settemperature to theoccupant's desiredcomfort. Ultra-thin,sleek design withcapacitive touch coloricons. Available inBlack or White shell.
•Enhanced energyefficiency throughmodulating control ofthe fan coil unit valveand ECM Fan support*.
•Automatic fan speedcontrol algorithmcalculates thedifference betweenthe room and the setvalue and automaticallyadjust the fan speed forgreater energy saving.
•Wide range of options to meet most of the requirements in buildings control. Additional functions include keypad lockout, timed shutdown and Modbus communications*.
*On selected models, please refer to the part number selection table.
VALVE AND FAN CONTROL
The WTS Series thermostat reads the room temperature from its built-in sensor and maintains the set temperature by sending on/off commands to the valve. There are three fan speeds which can be set manually or automatically. In manual mode, the fan speed is adjusted by FH, FM and FL outputs. In automatic mode, the fan speed will be decided by the difference between the room temperature and the set value. The fan will shut down when the valve is not operating.
Note : WTS3B4RXXX Models have Low and High Fan Speed only.
