Description

The MDT Room Temperature Controller Smart 55 with integrated temperature and humidity sensor is used for controlling the temperature of indoor rooms. Switch actuators / heating actuators can be controlled by the room temperature controller along with thermal actuators or motorised KNX actuators. In addition, the MDT Room Temperature Controller Smart has 4 binary inputs for connecting floating contacts.

The MDT Room Temperature Extension Unit Smart with an integrated temperature and humidity sensor is used for recording the temperature of indoor rooms. The extension unit can be operated either as a second unit along with the MDT Room Temperature Controller Smart (integrated temperature controller!) or as a stand-alone unit with the MDT Heating Actuator AKH (integrated temperature controller!).
