Wall thermostat with humidity sensor

Provides your personal comfort temperature

You get home on a cold and wet winter day longing for warmth and comfort. With Homematic IP , you enter inside your own four walls and always have the indoor climate that you need. Placed freely in the room, the wall thermostat optimally measures temperature and humidity and passes on all commands to the radiator thermostats. That means your home is always at the right temperature – not too warm and not too cold. Saving you up to 33 %* of valuable heating energy.
