6. What to do?

My operating panel indicates a malfunction
If the system detects a malfunction, then it notifies you of
this via the display. A code will be displayed on the screen
consisting of a letter and a number. Make a note of this
code.
• First try to cancel the malfunction by pressing "reset" in
the operating panel's information screen. Consult the op-
erating panel manual for instructions.
• Also check whether the ComfoCool and the heat ex-
changer are receiving power. On the side of the Comfo-
Cool is a plug socket. Check whether the plugs are firmly
fitted in the sockets.
• If the malfunction reoccurs, please contact a fitter spe-
cialised in ventilation and cooling technology.
My ComfoCool does not switch on
If your ComfoCool does not switch on like you expected,
then please check the following:
• Is the ventilation level correctly set? The ComfoCool will
not be activated in the Absent setting.
• Is the comfort temperature correctly set? Only when the
temperature in the room in which the operating panel is
located is higher than the set comfort temperature will the
system be activated.
• Is it cold outside? Active cooling is not activated when it
is cold outside (lower than 12˚C).
• Is it colder outside than inside? When it is colder outside
than inside, the system employs the bypass to ensure en-
ergy-efficient cooling. For further information, see section
3.
• Is it autumn or winter? The system does not use the ac-
tive cooling function in seasons in which the heating is
often on. However, if you still require cooling, then set the
comfort temperature to "COOL".
• Has active cooling been activated? A button for this pur-
pose can be found in the comfort temperature settings
menu. Only when this setting is set to "ComfoCool Auto"
will the ComfoCool be activated.
• Has the ComfoCool just been deactivated? For safety
reasons, it takes five minutes before the ComfoCool is
reactivated.
• Does the operating panel register the ComfoCool? This
will be visible in the ComfoControl Luxe main screen:
when the ComfoCool is registered, you will see a but-
ton in the comfort temperature settings screen stating
"ComfoCool Auto/ComfoCool OFF". If the ComfoCool is
not registered, remove the heat-recovery unit and Com-
foCool plugs from the socket. Reconnect the ComfoCool
first and then the heat-recovery unit.
My ComfoCool switches on but my dwelling
is not being cooled
If your dwelling does not cool (sufficiently) despite the
cooling being activated, then you can do the following:
• Set the ventilation to level 3. The more you ventilate, the
greater the volume of cooled air is supplied to the dwell-
ing.
• Fit sunblinds. The sun is an extremely powerful source of
heat. If your home receives a lot of sunlight, it will warm
up very quickly. This source of heat might well be strong-
er than the cooling effect created by your cooling system.

• Contrary to an air conditioner, the ComfoCool cools your
entire home. The ComfoCool is capable of reducing the
indoor temperature to a few degrees below what it would
be, were the ComfoCool turned off. In summer, we rec-
ommend setting the comfort temperature a couple of de-
grees lower than the outdoor temperature.
Irregular ventilation
If you have set the ventilation level to 1, the ComfoCool
will occasionally increase the throughput of the heat-re-
covery unit to keep the cooling components at an accept-
able temperature. If you prefer not to use this function,
then set the ventilation level to 2 or 3.
