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.

If you organized your radiator controls into groups and FRITZ!OS 7.20 or later is installed on your FRITZ!Box, the boost is enabled or disabled on all of the radiator controls in this group as soon as you switch the function on or off on one of the radiator controls in the group.

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. The duration you set remains valid until you change it again:

  1. After the boost starts, push the plus or minus button to set the desired duration. The display of the radiator control then shows the time when the boost will be deactivated again.
