Product description
The
Aero_aH 100
is a small room fan for
dehumidifying rooms, especially cellars, and similar
adjoining rooms. The device has a fixed indoor grille
and is equipped with an integrated indoor sensor.
Controlled dehumidification is achieved by a
comparison of the indoor and outdoor climate. This
requires the closing flap AP 100 with built-in outdoor
climate sensor to be connected. To support room
dehumidification, a ventilation fan can also be
controlled directly via the Aero_aH 100.

Dehumidification control
Efficient dehumidification of rooms with controlled
ventilation involves removing moist air from the
room while simultaneously supplying dry air.
For this purpose, the absolute humidity (aH) is
determined as a measure of the water vapour
content in the air by means of the two climate
sensors (indoor and outdoor sensor).
Measurements are taken immediately after the
device has been switched on. As soon as the
absolute outdoor humidity is lower than the
absolute indoor humidity (aHoutside < aHinside),
the fan of the Aero_aH 100 is automatically
switched on and a dehumidification period begins
(active time).
Ventilation and dehumidification take place
approximately every 10 minutes. Afterwards, the
fan is switched off for another 10 minutes so that
the moisture-loaded room air can mix with the drier
outdoor air supplied (passive time). After this
passive period, the climate comparison is repeated.
If the absolute humidity of the outdoor air is higher
than that of the indoor air during a climate
comparison (aHoutdoors > aHindoors), no air
exchange will be carried out. This prevents moist air
from flowing in. The fan is only switched on again
when the climate
