5 Maintenance

Make sure your ventilation system is checked and
cleaned by a installer once every 4 years. Note:
Only a recognised cooling-technology installer may
disassemble and clean the unit.
Cleaning condensation drain
Your ventilation system is fitted with siphons for the
condensation drain. When running, the unit discharges
no more than 2.5 litres of condensation an hour. It is
therefore important that the siphons and especially the
drain's waste-water connector are clean and clear of
blockages. Check your condensation drain once a year.
Cleaning ventilation valves
Your ventilation system is fitted with valves for air supply
and air exhaust. Exhaust valves are fitted in the wall
or ceiling of the kitchen, bathroom and toilet. Supply
valves are fitted in the wall or ceiling of the living room
and the bedrooms. If the valves become visibly dirty,
then clean them. Hold the valve on its outer edge and
pull it with a rotating movement entirely from the wall or
ceiling. Clean the valve with soap, then rinse it and dry
it. Always remount the valve in the wall or ceiling in the
same way you removed it. Take care not to swap the
valves, and try to avoid altering the valve settings.
Filters
Your ventilation unit is equipped with filters that prevent
the heat exchanger from becoming contaminated with
dust. It is very important that these filters are cleaned
or replaced occasionally. Consult the ventilation unit
manual for instructions.

6 What to do?

My operating panel indicates a malfunction
If the system detects a malfunction, then it notifies you
of this via the operating panel. Make a note of the code.
■ First try to cancel the malfunction by navigating to
RESET ERROR and selecting CONFIRM. Consult the
operating panel manual for instructions.
■ Also check whether the unit and ventilation unit are
receiving power. On the side of the unit is a plug
socket. Check whether the plugs are firmly fitted in
the sockets.
■ If the malfunction reoccurs, please contact an
installer specialised in ventilation and cooling
technology.
My unit does not switch on
If your unit does not switch on like you expected, then
please check the following:
■ Is the ventilation level correctly set? The unit will not
be activated in the Absent setting.
■ Is the temperature profile correctly set? Only when
the return temperature of the ventilation unit is higher
than the set temperature profile will the system be
activated.
■ Is it cold outside? Active air temperation 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 energy-efficient air temperation. For further
information, see section 3.
■ Is it autumn or winter? The system does not use the
active air temperation function in seasons in which
the heating is often on.
■ Is the unit temporary turned off? A menu for this
purpose can be found in the TASK MENU. Only when
this setting in menu COMFOCOOL is set to "AUTO"
will the unit be activated.
■ Has the unit just been deactivated? For safety
reasons, it takes five minutes before the unit is
reactivated.
■ Does the operating panel register with the unit? When
the unit is not registered the display on the ventilation
unit will display the malfunction code "CCOOL_
CONNECT ERROR".
My unit switches on but my dwelling is not being
tempered
If your dwelling does not cool (sufficiently) despite the
unit being activated, then you can do the following:
■ Set the ventilation to level 3. The more you ventilate,
the greater the volume of tempered air is supplied to
the dwelling.
■ 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 stronger than the air temperation effect
created by your unit.
■ The unit is capable of reducing the indoor
temperature to a few degrees below what it would be,
were the unit turned off. In summer, we recommend
setting the temperature profile to COOL.
Irregular ventilation
If you have set the ventilation level to 1, the unit will
occasionally increase the airflow of the ventilation unit
to keep the cooling components at an acceptable
temperature. If you prefer not to use this function, then
set the ventilation level to 2 or 3.
Your installer has set an ventilation scheduler on the
ventilation unit in which the ventilation unit will switch
between PRESET 3 and PRESET AWAY for 5 minuts a
day to optimize the functioning of the unit. No action is
needed.
