Pushing this key sets the supply and extract air mode.
Key
Extract air mode
Pushing this key sets the extract air mode only. The supply air mode
is switched off.
This key must be permanently deactivated
when operating the ventilation unit with a
fireplace! Simultaneous operation of a ventilation
system and fireplace imposes more stringent safety
requirements with regard to low pressure screening
and a switch-off function is required for the
ventilation unit.
Key
Supply air mode
Pushing this key sets the supply air mode only. The extract air mode
is switched off.
Key
Decreasing the fan speed
Pushing this key decreases the fan speed in increments.
Key
Increase fan speed
Pushing this key increases the fan speed in increments.
Key
Boost ventilation mode
Pushing this key activates the boost ventilation during the supply
and extract air mode on fan speed 7 for 15 minutes. At the end of
the boost ventilation time the previously active operating mode
resumes. You can cancel the boost ventilation mode at any time by
pressing another function key.
Key
Reset filter running time
To ensure cyclic filter inspection, the control has an integrated
operating hours counter. The reset filter running time key allows you
to reset the filter running time.
