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.

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.
