Ventilation and air extraction take place for
roughly 10 minutes. Then the fan is switched
off for a further 10 minutes so that the moist
room air can mix with the dry air brought in
from outside (passive time). After the waiting
period has lapsed, the comparison of the
inside and outside humidity is repeated.
If the absolute humidity of the outside air is
found to be greater than that of the air inside
the room (aH
outer
> aH
inner
), air is not
exchanged. This prevents moist air from
flowing in. The fan is only switched on again
once the climate conditions make
dehumidification possible.

* Simultaneous blinking:
Blinking of LED 1 or LED 2 indicates an
operating mode or function. If both LEDs blink
simultaneously, there is a fault. See chapter
Fault rectification.
Successful dehumidification –
Button 1 / Blinking LED 2:
In the case that the room humidity is reduced
by at least 0.2 g/m
3
, in comparison to the
reference value, the AKE 150 signals
successful dehumidification by LED 2
blinking. A reference value of 9 g/m
3
is set
on-site. A new reference value can be set at
any time by pushing button 1 during ongoing
operation. Saving of the new reference value
is confirmed by the LED 2 blinking briefly.
Frost protection:
To prevent the room from cooling down, the
AKE 150 has a frost protection function. This
means that the fan automatically switches
off at inside room temperatures of less than
5 °C.
Protection against insufficient humidity:
For reasons of health protection and energy
efficiency, the AKE 150 offers a protection
against insufficient humidity function. This
protective function ensures the switching off
of the fan if a relative humidity of less than
30 % is reached.
Manual ventilation – Button 2:
The AKE 150 switches the fan on and off
automatically and in a manner optimised to
demand. When off, the fan can be switched
on manually with button 2 and manual
ventilation therefore takes place. Manual
operation is ended by again pressing button 2
or automatically after approximately
20 minutes.
