In the winter, the heat-recovery unit ensures energy-effi-
cient ventilation in your dwelling, using the energy from
the stale exhaust air to heat the supply air to a comforta-
ble temperature. In the summer the system ensures ener-
gy-efficient cooling of your dwelling. The system employs
the following options for this purpose:
Where possible your selected comfort temperature
is maintained by opening the heat-recovery bypass
valve. Thereby guaranteeing continued ventilation
while ensuring cool supply air. This process usually
runs at night.
You will know that the bypass is activated when
a symbol appears on the ComfoControl Luxe:
o
stands for an open bypass valve;
o
means that the bypass is closed.
When the comfort temperature can no longer be
maintained by opening the bypass valve, then the
system begins active cooling by activating a cool-
ing circuit. This may be required on a hot, sunny
summer's day, or if there is a lot of sunlight in your
dwelling. The system lowers the temperature of the
supply air, cooling your home. Moreover, the system
extracts moisture from the air, adding to a pleasant
indoor climate.
You can see when the active cooling circuit is
on when a colling symbol
ComfoControl Luxe. The ComfoCool makes a
noise similar to a fridge.

4. Operation

Your ventilation system with cooling is controlled using
the ComfoControl Luxe operating panel. This is a touch
screen panel used to activate all of the units settings and
display the current unit status along with any malfunc-
tions. Consult the ComfoControl Luxe manual for more
detailed information. The system's key functions are:
The ventilation level. Select from the following set-
tings:
o

have). Only use this setting when you plan to be
away for an extended period. The ComfoCool is
always off when this setting is selected.
o
Level 1
this setting when there are fewer people than nor-
mal in your home.
o
Level 2
this setting when the dwelling is being used nor-
mally.
o
Level 3
this setting when you require extra ventilation, e.g.
when cooking, showering or if you are entertaining.
Also use this setting when the dwelling needs to be
cooled down considerably.
o
Temporary high level
setting, the system will ventilate at level three for
a given period. The system will then return to the
previous setting. Use this setting when cooking or
showering.

Your
ComfoCool-
equipped ventilation system tries continuously
to maintain the temperature of the room in which
the operating panel is located based on your set
comfort temperature. This comfort temperature
may have to be achieved by the unit automatically
opening the bypass valve or activating the active
cooling. For more information, read section 3.
o
The comfort temperature can be set to between
COOL and WARM, with temperatures varying
from 18˚C to 24˚C.
When COOL is selected, the system attempts to
keep the temperature as low as possible. If condi-
tions allow, active cooling will be activated. Use this
setting if you wish to cool the dwelling.
If WARM is selected, then the active cooling will
never be activated and the bypass remains closed.
Use this setting when you turn the heating up.
Your heat-recovery unit is fitted with a system that
detects whether it is summer or winter. In the sum-
mer, the active cooling can be activated, while this
is not desirable under normal winter conditions. All
the same, if you wish to use active cooling in the
winter, then set the temperature to COOL.
o Active cooling can be deactivated. In the screen
in which the comfort temperature can be entered,
you will see a button that can be set to either
"ComfoCool Auto" or "ComfoCool Off". Select
"ComfoCool Off" if you do not wish to use active
cooling, even if your dwelling gets warmer than
the required comfort temperature.

5. Maintenance

Please make sure your cooling-equipped ventilation sys-
tem is checked and cleaned by a fitter once every 4 years.
Note: Only a recognized cooling-technology fitter may
disassemble and clean the ComfoCool.

Cleaning condensation drain

Your ventilation system is fitted with siphons for the
condensation drain. When running, the ComfoCool dis-
charges 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 re-
mount 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 ComfoAir is equipped with filters that prevent the
ComfoAir's heat exchanger from becoming contaminated
with dust. It is very important that these filters are cleaned
or replaced occasionally. Consult the ComfoAir manual
for instructions.
