Rain/wind sensor
If a rain/wind sensor is installed, the windows will close automatically in the event of
rain or strong wind. As long as the rain/wind sensor is active, the windows cannot be
opened with the ventilator switch.
In the event of a fire alarm, the windows will also open when the rain/wind sensor is
active.
Power outage
In the event of a power outage, ventilation operation is disabled, which saves the bat-
teries for use in the event of a fire. It is only possible to close the windows which are
already open.

on the RWA switch is illuminated.

The RWA-Emergency Power Control System transmits external signals, for
