2. For the user
This chapter describes how to operate the ComfoAir.

2.1 Glossary
The ComfoAir features:
• Balanced ventilation;
• Heat recovery;
• Bypass for free cooling;
• Frost protection;
• Chimney sweep programme;
• 0 - 10V input;
• Pre-heater (optional);
• Afterheater (optional);
• Geothermal heat exchanger (optional);
• Enthalpy (optional).
A concise explanation of these concepts/features is
given in the paragraphs below.
2.1.1 Balanced ventilation
The ComfoAir is a balanced ventilation system.
Balanced ventilation means that pollutants from
the kitchen, the bathroom, the toilet(s) and possi-
bly the storage room are extracted, while the same
amount of fresh air is blown into the living room and
bedrooms. Gaps under the doors ensure a good
through-flow in the dwelling. The air circulation is
in balance.
Ensure that these gaps are never obstructed
by draught excluders or deep-pile carpet, for
example. Otherwise the system will not func-
tion optimally.
A balanced ventilation system consists of:
• ComfoAir (A);
• Duct system for the supply of outdoor air (B)
and the exhaust of indoor air (C);
• Supply valves in the living room and bedrooms
(D);
• Exhaust valves in the kitchen, bathroom, the
toilet and (if present) the storage room (E).

2.1.2 Heat recovery
Besides ensuring a healthy balance between incom-
ing and outgoing air, the ComfoAir also provides the
benefits of heat recovery. Heat recovery means that
heat from the extracted air is transferred to the fresh,
and usually colder, air from outside the building.
2.1.3 Bypass for free cooling
The bypass is often used during hot days in the
summer season. By allowing colder outside air in
at night, the indoor temperature of the dwelling can
be kept low during hot days. The bypass works au-
tomatically. All you have to do is set the required
comfort temperature.
2.1.4 Frost protection
The ComfoAir is also fitted with a frost protection
device. This is an automatic protective system that
temporarily reduces (or even briefly stops) the sup-
ply of outdoor air to the ComfoAir if there is a risk
of freezing in the ComfoAir. This can occur in the
event of moderate to sharp frost during the winter
months.
2.1.5 Chimney sweep programme
The ComfoAir is fitted with an Chimney sweep pro-
gramme. The chimney sweep programme is used in
houses that have a fireplace, as there is a risk of air
being sucked back from the chimney. The chimney
sweep programme works automatically but requires
activation by the installer. While the Chimney sweep
programme is activated the supply and exhaust fan
can not be turned off manually.
2.1.6 0-10V input
The ComfoAir is fitted with four 0 to 10V inputs. This
allows various different types of control system or
sensor to be connected. Examples of the options
include:
• CO2sensor; flow regulation using carbon diox-
ide levels;
• Moisture sensor; flow regulation using moisture
levels.
2.1.7 Pre-heater (optional)
Fitting the optional pre-heater in the ComfoAir gives
the added bonus that balanced ventilation remains
intact for longer. In that case, the supply of cold out-
side air no longer needs to be reduced (so soon).
The pre-heater is (de)activated automatically.
2.1.8 Afterheater (optional)
It is possible to fit the ventilation system with a af-
terheater. The afterheater ensures that the supply
air is heated further before it enters any living areas.
The advantage of an afterheater is that the sup-
ply air can be instantly released into the house at
the set comfort temperature. That offers additional
comfort.
The afterheater works automatically: simply set the
required comfort temperature.
The afterheater is part of the ducting of the
ventilation system, and does not form part of
the ComfoAir.

2
EN - 4 - For the user
2.1.9 Geothermal heat exchanger (optional)
It is possible to fit the ventilation system with a geo-
thermal heat exchanger. The geothermal heat ex-
changer ensures that outside air is supplied to the
dwelling at a constant temperature of about 8 °C.
Therefore, in the event of subzero temperatures, the
outside air can be heated up by means of the geo-
thermal heat exchanger, prior to releasing it into the
house via the ComfoAir. Alternatively, in the event
of hot summer conditions, the outside air can be
cooled down by means of the geothermal heat ex-
changer, prior to releasing it into the house via the
ComfoAir. The geothermal heat exchanger is auto-
mated.
The geothermal heat exchanger is part of the
ducting of the ventilation system, and does
not form part of the ComfoAir.
2.1.10Enthalpy (optional)
The ComfoAir can be optionally fitted with an en-
thalpy exchanger. An enthalpy exchanger is less
sensitive to freezing. An enthalpy system means the
ComfoAir uses the afterheater less, and no longer
reduces the air supply from outside, though it does
stop it in extreme cold.
2.1.11 Luxury version extra options
Besides the options stated earlier, the ComfoAir
Luxe also offers the following options:
• Connection for remote (fixed-line) malfunction
alerts;
• Connection for remote (fixed-line) deactivation
of the fans;
• Connection for filter alert for external filters.
2.2 Available operating devices
The ComfoAir can be fitted with the following
operating elements:
• 3-position switch;
• Wireless 3-position switch;
• 3-position switch with malfunction indicators;
• Bathroom switch to temporarily select the
highest ventilation position;
• CO2sensor;
• CC Luxe panel;
• CC Ease panel.
A concise explanation of these operating elements
is given in the paragraphs below.
2.2.1 3-position switch
A 3-position switch can be used to set the venti-
lation positions of the ComfoAir. One or multiple
3-position switches can be fitted in the house (e.g.
in the kitchen). The following types of switches can
be used:
• Type 1 JStandard 3-position switch;
• Type 2 J3-position switch with LED
for malfunction and filter alerts;
• Type 3 JWireless 3-position switch with:
LED for malfunction and filter indication.
If multiple position switches are available in
the house, the ComfoAir will switch to the
highest ventilation setting unless overruled by
an automated software programme.
Setting the ventilation using
3-position switch(es)
A 3-position switch can be used to set 3 different
ventilation positions.
• Position 1 JLow.
- Use for low ventilation levels.
• Position 2 Normal.
- Use if you require normal ven-
tilation.
• Position 3 High.
- Use this position during cook-
ing, showering and when addi-
tional ventilation is needed.

1
The CC Ease panel or CC Luxe panel can be
used to select an additional ventilation posi-
tion (the absent setting).
2.2.2 CO2sensor
The ComfoAir can also be operated using a CO2
sensor. A CO2sensor can be used either as a 3-po-
sition switch or to determine manually the ventila-
tion required by measuring CO2levels in the room
concerned.
2.2.3 Bathroom switch
A bathroom switch can be used to temporarily set
the ComfoAir in the highest ventilation level. This
switch is mostly fitted in the bathroom to extract any
excess moisture after showering, as soon as pos-
sible. The bathroom switches vary widely in model
and are therefore not illustrated here. If required, the
bathroom switch can be turned on and off using a
time delay entered via an digital operating device.
Delay timer
This ensures that the ComfoAir does not switch on
at the highest setting when activated, but first waits
for the delay timer to run its course.
If the bathroom switch is deactivated during
the delay timer period, then the ComfoAir
will remain at its current ventilation setting
and not switch to the highest setting.
The delay timer does not work with all types
of bathroom switches (e.g. pulse switches).
2

2
For the user - 5 - EN
Overrun timer
This ensures that the ComfoAir does not switch
back to the default (or preprogrammed) setting
when deactivated, but first waits for the overrun
timer to run its course. Once the programmed over-
run timer is complete, the ComfoAir returns to the
default (or preprogrammed) ventilation setting.
If the bathroom switch is turned off within
the programmed overrun timer period, then
the overrun function will be terminated.
Light switch
The functions of the bathroom switch can also be
integrated into a light switch.
2.2.4 CC Luxe panel
The ComfoAir can be operated by means of a CC
Luxe panel, which can be ordered separately. The
CC (Comfort Control) Luxe panel is an digital oper-
ating device which can be mounted on the wall in
the living room and from there communicates with
the ComfoAir. The CC Luxe panel is operated via a
touch screen.
2.2.5 CC Ease panel
The ComfoAir can be operated by means of a CC
Ease panel, which can be ordered separately. The
CC (Comfort Control) Ease panel is an digital oper-
ating device which can be mounted on the wall in
the living room and from there communicates with
the ComfoAir.

2.4 Maintenance by the user
As a user of the ComfoAir, you must carry out the
following maintenance:
• Cleaning or replacing the filters;
• Cleaning the valves (in the dwelling).
A concise explanation of these maintenance
activities is given in the paragraphs below.
Failure to carry out (periodic) maintenance
on the ComfoAir ultimately compromises the
performance of the ventilation system.
2.4.1 Cleaning or replacing the filters
If so indicated on the digital operating device, you
must clean or replace the filters.
• “ FILTER I” The internal filters must be
cleaned or replaced.
• “ FILTER E” The external filters must be
cleaned or replaced.
The CC Ease panel will display one of the above
filter warnings.
The internal filters are included in the stand-
ard configuration of the ComfoAir. The exter-
nal filters (optional) form part of the ducting
of the ventilation system yet do not form part
of the ComfoAir.
To replace ...
If the filters need replacing, follow this procedure:
• Press “ “ (CC Ease panel) for at least 4
seconds until the filter warning disappears.
• Disconnect the power from the ComfoAir.
• Remove handles (A) from the ComfoAir.
• Remove the old filters (B) from the ComfoAir.
• Insert the new filter in the ComfoAir.
• Remount the handles on the ComfoAir
• Reconnect the power to the ComfoAir.
AA
B
To clean...
Vacuum the filters (B) with a vacuum cleaner instead
of replacing them with new filters.
When using the ComfoAir for the first time,
it is recommended to clean the filters (and
valves) first. During the construction phase
the ventilation system could have become
dirty with building dust.
Replace the filters (at least) once a year.
2.4.2 Cleaning the valves (in your dwelling)
The ventilation system may be fitted with the fol-
lowing valves:
Exhaust valve (STB) Exhaust valve (STC)
Exhaust valve (STV) Exhaust valve (STK)
Supply valve (STH)
You must clean the valves (at least) twice a year:
• Remove the valve from the wall or ceiling;
• Clean the valve in soapy warm water;
• Rinse the valve thoroughly and wipe dry;
• Place the valve back WITH EXACTLY THE
SAME SETTING (and IN THE SAME HOLE);
• Repeat this procedure for the other valves.

EN - 14 - For the user
About the valve settings...
The installer will have set all the valves to ensure
the optimum performance of the ventilation system.
Therefore, do not change the setting of the valves.
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.
The ventilation air is supplied and discharged by
means of valves. Gaps under doors in the dwell-
ing ensure that the air flows in the right direction.
In order to ensure that the ventilation volumes are
maintained in the rooms, the following must be ob-
served:
• Do not seal the gaps;
• Do not change the settings of the valves;
• Do not replace the valves with one another.
2.5 Malfunctions
Malfunctions in the ComfoAir are reported as fol-
lows:
• 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 these maintenance activi-
ties is given in the paragraphs below.
2.5.1 Malfunction alerts on the digital
operating device
In the event of a malfunction, the corresponding
malfunction code will be displayed on the digital
operating device. The the digital operating device
will always show an 'A' or an 'E', with a number as
a suffix. Please refer to the malfunction 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 has
occurred. Depending on the type of the 3-posi-
tion switch, this is done in one of the following two
ways:
• 3-position switch with malfunction indicators.
In the event of a malfunction (or in the event of
a filter dirty alert) the indicator lights up.
• Wireless 3-position switch with malfunction in-
dicator.
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 malfunction (and in the event of a filter dirty
alert) both indicators will flash red 3 times. Af-
ter 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, it will also light up in the
event of filter cleaning 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
ComfoAir 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 ComfoAir 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 build-
up of moisture and results in problems with
mould. Long-term deactivation of the Com-
foAir must therefore be prevented..
2.6 End of useful life
Consult with your supplier about what you should
do 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 recy-
cling the components or processing the materials
in an environmentally friendly manner.
Furthermore, do not dispose of batteries from the
wireless switches with the normal waste, but bring
them to the specially designated disposal loca-
tions.
