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


Please Note: The FT-09 FCU thermostat utilizes a high-reliability relay module with a maximum of 9 terminals. Due to terminal capacity, specific terminal assignments depend on your selected configuration (e.g., Modbus vs. BACnet, or 3-speed vs. EC fan). Please choose the wiring scheme that aligns with your specific project requirements.

Our FT-09 controller is engineered to meet the highest international standards for safety, reliability, and environmental responsibility:
Safety & EMC: Fully compliant with CE (RED/LVD/EMC), UKCA, FCC, and ETL Listed standards.
Environmental: Certified by RoHS and REACH, ensuring lead-free and eco-friendly manufacturing.
