flowing in. The fan is only switched on again
once the climate conditions make
dehumidification possible.

* Simultaneous blinking:
Simultaneous 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 100 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 100 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 100 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
100 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.
Optionally, manual operation can take place
with an external button, see wiring diagram in
Chapter 15. The fan cannot be switched off
manually using the button when in the
automatic operating mode.
