Automatic ventilation profiles
The automatic ventilation profiles do not follow a 7-day timer and cannot be programmed by the
user. With these ventilation profiles, ventilation behaviour is determined by temperature and
humidity variables in two environments (inside the usage unit and outside). An outdoor sensor
(Outdoor humidity/temperature sensor) is therefore absolutely essential for all automatic
ventilation profiles.
To be able to use the cellar ventilation profiles, an Indoor humidity/temperature sensor,
CO
2
sensor
or controller in the cellar ventilation zone is also required.
The automatic ventilation profiles are:
• Summer mode
This ventilation profile can be used during the warm season for the desired ventilation zone(s).
There is then a constant comparison of the outdoor and indoor temperatures. Based on the
temperature values, the system automatically decides whether the indoor climate should be
maintained or whether "passive cooling" should be carried out with the ventilation function. After
the end of the warm period, the summer mode should be replaced by a different ventilation profile.
To prevent accidental operation outside summer time, the automatic ventilation function is only
activated when the outdoor temperature exceeds 16 ºC.
• Cellar ventilation
This ventilation profile works without heat recovery and is suitable for unheated cellars and
storage rooms. The aim is to prevent mould by specifically regulating the moisture content of the
room air. With cellar ventilation, automatic dew point control is achieved by continuously com-
paring the absolute humidity and temperature values of outdoor air and cellar room air. Based
on these values, the system automatically calculates the ideal times to remove moisture via the
ventilation function. If, on the other hand, there is a risk of moisture ingress from the outside, the
system pauses and closes the automatic closing flaps. The closed flaps prevent a passive inflow
of moisture-laden outdoor air.
• Cellar ventilation with heat recovery (HR)
This ventilation profile works with heat recovery and is suitable for all heated rooms below ground
level. The aim is to prevent mould by specifically regulating the moisture content of the room air.
With cellar ventilation, automatic dew point control is achieved by continuously comparing the ab-
solute humidity and temperature values of outdoor air and cellar room air. Based on these values,
the system automatically calculates the most suitable ventilation level and switches automatically
between heat recovery and ventilation depending on environmental conditions. If there is a risk of
moisture ingress from the outside, the system pauses and closes the automatic closing flaps. The
closed flaps prevent a passive inflow of moisture-laden outdoor air.
