The boost function offers the possibility of overriding the “automatic” mode for a period of between 5 and 120 minutes and heating (not cooling) the room during this period.

Default: 30 Min.

The set time is counted down on the display.

ATTENTION
The boost function is not interrupted even when the stored target temperature is reached. This only occurs when the countdown expires or when manually terminated in the menu BOS.

NOTE
If the thermostat is in cooling mode (due to an automatic CO signal or a manual switchover in the WMO), menu item), the BOS menu item is not shown on the display and is not available for parameterization.
