* When AUTO mode is active any adjustments will be overruled by
the next programmed scheduler step. If no schedule has been
programmed, the adjustment will be active for two hours. Schedules
cannot be set on the Comfoswitch, this has to be done on another
device as e.g. the HRU display.
When no button is pressed for
10 seconds all LED indicators will dim to
the set brightness. If the set brightness
is set to fully dimmed, one of the buttons
needs to be pressed to activate the
panel. The action of the pressed button
will be ignored.
4 Boost
The ventilation airow can be set to a
maximum (BOOST) for 30 minutes. This
can be useful when additional ventilation
is needed for a short time.
Turn on the Boost
1. Press and hold + for 3 seconds.
LED 1 and LED 2 are on and LED
3 is blinking.
Turn off the Boost
The Boost will automatically turn off after
30 minutes.
To directly turn off the Boost Timer:

turned off and the device returns to
the previous setting.
Remark: the boost could also be
activated for shorter or longer periods
than 30 minutes by using other control
devices e.g. like the HRU display.
