Room temperature control device for properties. For System M. KNX room temperature controller for real estate with integrated bus coupler. Depending on the operating mode, the current temperature setpoint, and the current room temperature, a control signal for heating or cooling is transmitted to the KNX. The temperature can be measured either via the internal or an external bus temperature sensor. The room temperature controller can be used for heating and cooling with continuously adjustable KNX valve actuators or for controlling switching actuators and heating actuators. Operating mode, setpoint, and control functions can only be adjusted via the bus. The device has no operating or display elements. With integrated bus coupler. The bus is connected via a bus terminal.

Functions of the room temperature controller: Controller type: 2-point control, continuous PI controller, switching PI controller (PWM). Output: continuous in the range of 0 to 100% or switching ON/OFF. Controller modes: Heating with one control output, cooling with one control output, heating and cooling with separate control outputs, heating and cooling with one control output, 2-stage heating with 2 control outputs, 2-stage cooling with 2 control outputs, 2-stage heating and cooling with 4 control outputs. Operating modes: Comfort, comfort extension, standby, night setback, frost/heat protection.

Shifting of all setpoints, storing all set temperatures and operating modes upon reset, external temperature monitoring, additional output of the control signal as a 1-byte value on the PWM. Monitoring function for the actual temperature, valve protection function. Operation: only via bus telegrams. Contents: With bus terminal and carrier plate. With protective cover for plaster. Material: glossy thermoplastic. Color: polar white, glossy.
