Manual operation is ended by again pressing but-
ton 2 or automatically after approximately 20
minutes.
Optionally, manual operation can take place with
an external button, see
Wiring diagrams [ } 36] .
The fan cannot be switched off manually using
the button when in the automatic operating mode.
Manual ventilation – external button/switch:
Optionally to button 2, manual operation can take
place with an external button or switch, see
Wir-
ing diagrams [ } 36] .
To achieve this, an automatic button/switch re-
cognition via the duration of the first activation
after power is supplied. A switch is recognised
when the switching contact is closed for more
than 10 seconds.
Manual ventilation with an external button is equi-
valent to using button 2.
If an external switch is connected, manual ventila-
tion is switched on or off in accordance with the
switch setting. An automatic switch-off of the
manual operating mode does not exist in this
case.
Manual ventilation is also possible during
frost protection and protection against insuffi-
cient humidity.
NOTICE Damage to the building fabric due to
manual ventilation
Excess manual ventilation can lead to room hu-
midification if the outdoor conditions are humid.
Therefore, you must pay attention to the duration
of the manual ventilation when using an external
switch.

ation location, see above for spacing. Feed
the power cable at least 110 mm out from
the wall
.
7.2 Ceiling
1. Perform installation preparations as described
in Chapter Wall [ } 18] .
NOTICE Danger of short-circuits and damage
to unit if condensation builds up in the fan
housing.
Thermally insulate ventilation ducts properly. Al-
low for a condensation drain or condensate col-
lector in the riser.
