Using a radiator control in the FRITZ!Box home network

Since the radiator control functions according to the DECT ULE (Ultra Low Energy) standard, it communicates with the FRITZ!Box at greater intervals to save energy and minimize DECT radiation. As a result, it may take up to 15 minutes for the settings to be transferred to the radiator control. It may even take up to 60 minutes during vacation switching and the phase when the radiator is turned off. By pushing any button on the radiator control, you can cause the settings to be transmitted immediately.
