Indoor Sensor (Temperature, Humidity)

The Temperature and Humidity Sensor WGTH-UP is an addition to the Control Systems WS1 Color/Style, WS1000 Color/Style and KNX WS1000 Color/Style (from version 1.0). Instead of using the delivered frame, it is possible to take a frame of the switching series installed in the building. Thus the sensor merges with the interior.
