  • Description

    Tuya WIFI Smart Fan Coil Room Thermostat TP518series 


    This digital programmable heating and cooling FCU thermostat is designed to controls the fans, valves, dampers or electric heater in fan coil units and heating applications.

     It detects the room temperature with its integrated temperature sensor and compares it with the setpoint temperature. In the event of a deviation, the heating valve is opened 


    in heating mode, and the cooling valve is opened for cooling mode. At the same time, the connected fan is activated depending on the control deviation and the set configuration.

     A connectable remote sensor can be used either for detecting the room temperature or as a changeover  sensor in 2-pipe systems
