An FCU thermostat is a room controller used to manage the operation of a fan coil unit. It measures the indoor temperature, compares it with the selected setpoint and controls the fan and valve to deliver the required heating or cooling output.
The MENRED RT2 is developed for 2-pipe FCU systems, where the same water circuit is used for heating or cooling according to the building’s seasonal operating mode.

When the room temperature differs from the selected setpoint, the RT2 controls the connected fan coil unit and valve actuator according to the required operating condition. This provides consistent temperature regulation without unnecessary manual adjustment.
The Tuya WiFi configuration allows users to adjust temperatures, create schedules and monitor the thermostat remotely through a compatible smartphone application.
The RS485 configuration supports communication with compatible building control networks, making it suitable for hotels, offices, apartments and other multi-zone HVAC projects.
WiFi and RS485 availability depends on the selected RT2 model. Please confirm the communication requirements and control protocol before ordering.
