After cleaning, make sure that all valves are
placed back with the same setting (and in
exactly the same ventilation hole in the wall
or ceiling) AT ALL TIMES. Otherwise, system
performance will be compromised.
2.5 Malfunctions
Malfunctions in the ComfoAir are reported as follows:
• The malfunction alert appears on the CC Ease
panel;
• The malfunction alert appears on the CC Luxe
panel;
• 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 mal-
function code will be displayed on the digital operating
device of the ComfoAir. Please refer to the malfunc-
tion 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 indi-
cator.
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 mal-
functionor 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 Com-
foAir 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 Com-
foAir must be taken out of service due to a serious
malfunction, or for filter cleaning/replacement 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 bu-
ild-up of moisture and results in problems
with mould. Long-term deactivation of the
ComfoAir 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 recycling the
components or processing the materials in an envi-
ronmentally 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.
