5 For the user
If the bathroom switch is deactivated during
the delay timer period, then the ComfoAir
will remain at its current ventilation setting
and not switch to the highest setting.
The delay timer does not work with all types
of bathroom switches (e.g. pulse switches).
Overrun timer
This ensures that the ComfoAir does not switch back
to the default (or preprogrammed) setting when de-
activated, but fi rst waits for the overrun timer to run
its course. Once the programmed overrun timer is
complete, the ComfoAir returns to the default (or
preprogrammed) ventilation setting.
If the bathroom switch is turned off within
the programmed overrun timer period, then
the overrun function will be terminated.
Light switch
The functions of the bathroom switch can also be
integrated into a light switch.
