Using the boost function of the FRITZ!DECT radiator control (rapid heating)

If you want to heat a room quickly, you can simply use the boost function directly on the radiator control, for example FRITZ!DECT 301. The radiator control then heats at full power for the amount of time you select.

1 Switching boost on and off

  1. Push the "Menu" button on the radiator control for 2 seconds. Now the radiator control heats at full power for the amount of time displayed.
  2. If you want to end the boost before the time is up, push the "Menu" button again for 2 seconds.

2 Changing the boost duration

By default, the boost duration is 15 minutes. You can set your own boost duration:

  1. After the boost starts, turn the wheel on the radiator control to set the desired duration. The display of the radiator controller then shows the number of minutes left before the boost is deactivated again, for example "B 20".
