Triggering Open Window Detection

If you open a window for a longer period of time, the temperature in the room can drop sharply as a consequence. The FRITZ!DECT 301 radiator control therefore automatically closes the radiator valve after up to 2 minutes to save energy.

You can set the sensitivity of the open window detection function (low, medium, high) and specify the length of time the valve remains closed. Open window detection is always enabled and switches on automatically.
