Up to three adjustable weekly profiles: The room temperature can be regulated based on a schedule (up to 6 heating phases per day with individually adjustable temperature). In conjunction with the Homematic IP window and door contact, the temperature is automatically lowered as soon as a window is opened. The metal nut ensures a secure fit on all common radiators. Easy installation without draining water or interfering with the heating system. Temperature changes and activation of the boost function (rapid heating of the radiator) can be done directly on the device.
