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 drives or for controlling switching actuators and heating actuators. Operating mode, setpoint, and control functions can only be set via the bus. The device has no operating or display elements. With integrated bus coupler. The bus is connected via a bus connection 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 controller output, cooling with one controller output, heating and cooling with separate controller outputs, heating and cooling with one controller output, 2-stage heating with 2 controller outputs, 2-stage cooling with 2 controller outputs, 2-stage heating and cooling with 4 controller outputs. Operating modes: Comfort, comfort extension, standby, night reduction, frost/heat protection. Shifting of all setpoints, saving 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.
