MERTEN KNX Regulator wf.temp. B.P. S.M.

Room temperature control unit for properties. For System M. KNX room temperature control unit for properties with integrated bus coupler. Depending on the operating mode, the current temperature setpoint value and the actual room temperature, a control value for the heating or cooling control unit is transmitted to the KNX. The temperature can optionally be measured by the internal or by an external bus temperature sensor. The room temperature control unit can be used for heating and cooling with infinitely adjustable KNX valve drives or to trigger switch actuators and heating actuators. Operating mode, nominal value, control function settings made only via the bus The device does not have any operating and display elements. With integrated bus coupler. The bus is connected using a bus connecting terminal. KNX software functions:. Functions of the room temperature control unit: Controller type: 2-step control, continuous PI controller.
