It two contradictory automatic functions overlap, the automatic function further down
the list has priority.
Rain alarm for automatically controlled windows:
If rain is entering, it may be some time before rain is detected by the sensors in the sys-
tem, depending on the amount of rain and outside temperature. In addition, a closing
time for electric windows or sliding roofs has to be included in the calculation. Mois-
ture-sensitive objects should therefore not be placed in areas where thy could be dam-
aged by entering precipitation. Please also bear in mind that in the event of a power
failure and rainfall, a window will not be automatically closed if no emergency gener-
ator is installed.
Alarm functions
The alarm functions are applied to windows in manual mode and automatic mode.
All windows are closed if there is a
frost, wind or rain alarm
and cannot be extended
manually. Gap ventilation during a rain alarm is an exception; in automatic mode it
only restricts the window's range of motion.
Ventilation settings
The settings are only executed if a window is in automatic mode and none of the alarm
functions named above is active.
Timed closing
has the highest priority, followed by the
VOC value of the outside
air
(keep closed and open), the
outdoor temperature lock
(keep closed),
timed
ventilation
(open),
supply air temperature lock
(keep closed) and
night back
cooling
(open).
