2.5.2 3-position switch with malfunction
indicators
The 3-position switches that are fi tted with a malfunc-
tion indicator show when a malfunction has occurred.
Depending on the type of the 3-position switch, this
is done in one of the following two ways:
• 3-position switch with malfunction indicator.
In the event of a malfunction (or in the event of a
fi lter dirty alert) the indicator lights up;
• Wireless (RF) 3-position switch with malfunction
indicator.
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-
function (and in the event of a fi lter dirty alert)
both indicators will fl ash red 3 times. After that,
both indicators will light up green once more.
The malfunction indicator on the 3-position
switch will not light up in the event of mal-
functions alone, but will also light up in the
event of fi lter replacement warnings.
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 identifi cation 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 fi lter
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 build-
up of moisture and results in problems with
mould. Long-term deactivation of the Com-
foAir 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 conden-
sation 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 com-
ponents or processing the materials in an environ-
mentally friendly manner.
Furthermore, do
not dispose of batteries from the wi-
reless (RF) switches with the normal waste, but bring
them to the specially designated disposal locations.
