2.5 Malfunctions
Malfunctions in the ComfoAir are reported as fol-
lows:
• The malfunction alert appears on the display.
• The malfunction indicator on the 3-position
switch lights up;
A concise explanation of methods of reporting mal-
functions is given in the paragraphs below.
2.5.1 Malfunction alerts on the digital
operating device
In the event of a malfunction, the corresponding
malfunction code will be displayed on the digital
operating device of the ComfoAir. Please refer to
the malfunction overview to find out the meaning of
the relevant malfunction alert.
2.5.2 3-position switch with malfunction
indicators
The 3-position switches that are fitted with a mal-
function indicator show when a malfunction or filter
dirty alert has occurred. Depending on the type of
the 3-position switch, this is done in one of the fol-
lowing two ways:
• 3-position switch with malfunction indicator.
In the event of a malfunction or filter dirty alert
the indicator lights up;
• Wireless 3-position switch with malfunction in-
dicator.
The malfunction indicators will light up once
this 3-position switch is used. One indicator
will light up green to indicate communication
has been established. Subsequently, in the
event of a malfunctionor filter dirty alert both
indicators will flash red 3 times. After that, both
indicators will light up green once more.
2.5.3 What to do in the event of a malfunction
In the event of a malfunction, contact the installer.
Note down the malfunction code that appears on
the digital operating device. Make a note of your
ComfoAir type. This is given on the identification
plate on the top of the ComfoAir. The system should
not be disconnected from the power supply, unless
the ComfoAir must be taken out of service due to
a serious malfunction, or for filter cleaning/replace-
ment or any other compelling reasons.
If the ComfoAir is disconnected from the
power supply, mechanical ventilation of the
dwelling will cease. This can lead to a build-
up of moisture and results in problems with
mould. Long-term deactivation of the Comfo-
Air must therefore be prevented.
If the ComfoAir is installed in an area with a
higher average humidity (such as bathroom
or toilet) the probability of condensation on
the outside of the ComfoAir is high. This is a
normal phenomenon, similar to condensation
on a window, on which no action is needed.
2.6 End of useful life
Consult with the supplier about what should be
done with the ComfoAir at the end of its useful life.
If the ComfoAir cannot be returned to the supplier,
avoid disposing of it with the domestic waste, and
ask your local council about the options for recy-
cling the components or processing the materials
in an environmentally friendly manner.
Furthermore, do
not
dispose of batteries from the
wireless (RF) switches with the normal waste, but
bring them to the specially designated disposal lo-
cations.
