The ELEKTROBOCK HD13-L radiator controller is the perfect choice to save on heating costs while increasing comfort in your home. With the possibility to set an individual weekly program with 8 time periods and 2 temperature values per day, you can optimally adjust the heating output in any room. The clear backlit display shows you all the important information at a glance: valve opening in %, desired temperature and current time alternate in 2-second intervals. A clear graphic illustrates the progress of the set temperature program. Thanks to the window open detection, the radiator controller automatically detects when a room is ventilated, and closes the valve immediately to save energy.

No app or WiFi is required for use. With the ELEKTROBOCK HD13-L radiator controller you have full control over your heating costs and at the same time ensure a pleasant indoor climate.
