9. Switch the unit back into the desired operating mode.
Resetting the filter runtime
After completing the filter replacement, the meter for the filter runtime must be reset. To do this, you can clear the filter
inspection indication again by pressing the (-) and (+) button for 3 seconds. The red LED on the control panel, symbolizing
the filter replacement, switches off.
What should I do in case of a malfunction?
Contact the installation technician in case of a malfunction. Note down the type of your ComfoSpot 50; for more on this,
see the type label on the bottom cover of the interior cover.
The mains connection must always be present, providing the ComfoSpot 50 does not have to be shut down due to a
serious malfunction, maintenance work, or due to another urgent cause.
As soon as a mains disconnection is made, the apartment will no longer be mechanically ventilated. This
makes it possible for problems involving moisture and mould to occur in the apartment. A longer period
of being switched off, particularly during the summer months, brings about the danger of accumulating
insects in the inside of the outside wall panel and in the EPP housing section of the pipe extension!
The ventilation unit must be permanently left in operation, excepting times needed for maintenance and
repair work. The unit should be operated in the Away mode for the duration of an absence!
Disposal
Discuss with your supplier what you should do with your ComfoSpot 50 at the end of its life cycle. If you cannot return your
ventilation unit, do not dispose of it with the normal household waste, but rather contact your local authority for options to
recycle components or to process materials in an environmentally-friendly way.
