2 For the user
This chapter describes how to operate the ComfoAir.
Congratulations, you are the owner of a
ComfoAir 200, of Zehnder.
We wish you lots of comfort.
2.1 Glossary
The ComfoAir features:
• Balanced ventilation;
• Heat recovery;
• Bypass for free cooling;
• Frost protection;
• Chimney sweep programme;
• 0 - 10V input;
• Frost-free element (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 dirty air from the
kitchen, the bathroom, the toilet(s) and possibly the
storage room is 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. The system will not function opti-
mally.
A balanced ventilation system consists of:
• ComfoAir 200 (A);
• Duct system for the supply of outdoor air (B)
and the discharge 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 in-
coming and outgoing air, the ComfoAir also pro-
vides 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 requi-
res activation by the installer.
2.1.6 0-10V input
The ComfoAir has a single input.
This input allows various different types of control
system or sensor to be connected. Examples of the
options include:
• CO2sensor; regulation using carbon dioxide
levels;
• Moisture sensor; regulation using moisture lev-
els;
2.1.7 Frost-free element (optional)
Fitting the optional frost-free element in the Com-
foAir gives the added bonus that balanced venti-
lation remains intact for longer. In that case, the
supply of cold outside air no longer needs to be
reduced (so soon). The frost-free element is (de)ac-
tivated automatically.
2.1.8 Enthalpy (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 frost-free element less, and no
longer reduces the air supply from outside, though
it does stop it in extreme cold.

2.2.2 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 JCordless 3-position switch with
LED for malfunction and filter indication.
With regard to ventilation, if multiple position
switches are available in the house, the Com-
foAir will switch to the highest ventilation set-
ting unless overruled by an automated soft-
ware programme.

Setting the ventilation using
3-position switch(es)
A 3-position switch can be used to set 3 different
ventilation positions.
• Position 1 J Low.
- 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.
3
2
1
In addition to these 3 ventilation positions,
the CC Ease panel or CC Luxe panel can be
used to select an additional ventilation posi-
tion (the absent setting).
2.2.3 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.
2.2.4 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
possible. 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 a digital op-
erating device.
Activation delay
This ensures that the ComfoAir does not switch on
at the highest setting when activated, but first waits
for the activation delay to run its course.
If the bathroom switch is deactivated during
the activation delay period, then the Com-
foAir will remain at its current ventilation
setting and not switch to the highest set-
ting.
The activation delay does not work with
all types of bathroom switches (e.g. pulse
switches). In that case, leave the activation
delay at 0.
Deactivation delay
This ensures that the ComfoAir does not switch back
to the default (or preprogrammed) setting when de-
activated, but first waits for the deactivation delay
to run its course. Once the programmed deactiva-
tion delay is complete, the ComfoAir returns to the
default (or preprogrammed) ventilation setting.
If the bathroom switch is turned off within
the programmed deactivation delay period,
then the deactivation function will be termi-
nated.
Light switch
The functions of the bathroom switch can also be
integrated into a light switch.
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 a digital op-
erating device which can be mounted on the wall in
the living room and from there communicates with
the ComfoAir. The following overview summarizes
the information that will be displayed.

overridden by a time delay function (such as the
bathroom switch deactivation delay), a 't' is dis-
played in the bottom right-hand corner of the CC
Ease panel.
In the event a required ventilation setting is being
overridden by a signal from a sensor (such as a CO2
sensor), an 'A' is displayed in the bottom right-hand
corner of the CC Ease panel.
Setting the ventilation volume
The ventilation volume can also be set manually by
increasing or decreasing it. A total of 4 ventilation
volumes/levels can be set. They are:
• Setting A Absent.

2.4 Maintenance by the user
As a user of the ComfoAir, you must carry out
the following maintenance:
• 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) mainte-
nance on the ComfoAir ultimately com-
promises the performance of the ventila-
tion system.
2.4.1 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
replaced.
• “ FILTER E” The external filters* must be
cleaned or replaced.
The CC Ease panel will display one of the above
filter warnings.
You will see the message “FiL” and ”tEr” ap-
pearing alternately on the display.
The internal filters are included in the
standard configuration of the ComfoAir.
The external 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 proce-
dure:
• Press “ ” on the CC Ease panel or
“OK” on the display until the filter alert dis-
appears.
• Unplug the ComfoAir.
• Remove the filter caps (A) from the Com-
foAir.
• Remove the old filters (B) from the
ComfoAir
B
• Slide the new filter back into the ComfoAir.
• Refit the filter caps (A) to the ComfoAir.
• Plug the ComfoAir back in.
When using the ComfoAir for the first
time, it is recommended to replace the
filters and clean the valves first, as dur-
ing the construction phase the ventila-
tion 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 a solution of soap and 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.
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 dwelling
ensure that the air flows in the right direction. In or-
der to ensure that the correct ventilation volumes
are maintained in the rooms, the following must be
observed:
• 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 indicator on the 3-position
switch lights up;
• The malfunction alert appears on the display.
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 of the ComfoAir. The digital oper-
ating device will always show an 'A' or an 'E', with
a number as a suffix. Please refer to the malfunc-
tion overview to find out the meaning of the relevant
malfunction alert.

EN - 14 - For the user
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 indicator.
In the event of a malfunction (or in the event of
a filter dirty alert) the indicator lights up.
• Cordless 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 malfunction (and in the event of a
filter dirty alert) both indicators will flash 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 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 unplugged, unless the
ComfoAir must be taken out of service due to a se-
rious malfunction, or for filter cleaning/replacement
or any other compelling reasons.
When the unit is unplugged, the dwelling
will no longer enjoy mechanical ventilation,
and this can lead to problems with damp and
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
cordless switches with the normal waste, but bring
them to the specially designated disposal loca-
tions.
