2 For the user
Congratulations, you are the owner of a
ComfoAir 160,
a heat recovery unit from Zehnder.
We wish you lots of comfort.
2.1 Glossary
The ComfoAir features:
• Balancedventilation;
• Heatrecovery;
• Bypassforfreecooling;
• Frostprotection;
• Openreprogramme;
• Wireless(RF)control(optional)
• Enthalpy(optional);
• Analogueinput(0-10V).
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 possibly the storage room are
extracted, while the same amount of fresh air is blown
into the living room and bedrooms. Gaps under or near
thedoorsensureagoodthrough-owofairinthedwell-
ing. The air circulation is in balance.
Ensure that these gaps are never obstructed ,
for example by draught excluders or deep-pile
carpet. Otherwise the system will not function
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 incoming
andoutgoingair,theComfoAiralsoprovidesthebenets
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 in-
door temperature of the dwelling can be kept low during
hot days. The bypass works automatically: simply set the
required comfort temperature.
The bypass will always stay open for half an hour
2.1.4 Frost protection
TheComfoAirisalsottedwithafrostprotectiondevice.
This is an automatic protective system that temporarily
reduces(orevenbrieystops)thesupply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 Openreprogramme
TheComfoAiristtedwithanOpenreprogramme.The
Openreprogrammeisusedinhousesthathaveare-
place, as there is a risk of air being sucked back from the
chimney.TheOpenreprogrammeworksautomatically
but requires activation by the installer.
While the Open fire programme is activated the supply
and exhaust fan cannot be turned off manually.
2.1.6 Wireless (RF) control (optional)
It is possible to set the ventilation positions of the Com-
foAir with one or more wireless switches. To do this the
ComfoAir needs a built in RF module or a connected CC
Ease panel.

2.1.7 Enthalpy (optional)
It is possible to t the ComfoAir with an enthalpy ex-
changer. An enthalpy exchanger helps to regulate hu-
midity levels in the dwelling. In addition to heat recovery,
the enthalpy exchanger also ensures moisture recovery.
Moisture recovery means that moisture from extracted air
is transferred to the supply air sourced from outside the
dwelling. An enthalpy exchanger is also less sensitive to
freezing.
2.1.8 Analogue input (0-10V)
TheComfoAirLuxeisttedwithoneinput(0-10V).This
input can be used to connect a sensor or control
system to the ComfoAir. Examples of the options include:
• CO2sensor;owregulationusingcarbondioxide
levels;
• Moisturesensor;owregulationusingmoisturele-
vels;
2.2 Available operating devices
The ComfoAir is tted with the following operating de-
vices:
• Displayontheunit;
• 3-positionswitch;
• 3-positionswitchwithmalfunctionindicator;

2.2.2 3-position switch
A 3-position switch can be used to set the ventilation
positions of the ComfoAir. One or multiple 3-position
switchescanbettedinthehouse(e.g.inthekitchen).
The following types of switches can be used:

Setting the ventilation using
3-position switch(es)
A 3-position switch can be used to set 3 different ventila-
tion positions.
• Position1gLow.
- Use for low ventilation levels.
• Position2Normal.
- Use when present and no extra
ventilation is needed.
• Position3High.
- Use during cooking, showering
and when additional ventilation is
needed.
• TimerTemporary High
- Use during cooking, showering and
when additional ventilation is needed
for a short time.
The wireless 3-position switches have a separate but-
ton for the Timer. After the timer delay the ComfoAir will
return to the ventilation setting which was active before
the timer function was activated.
To use the Timer function with a wired 3-position switch
choose setting 3 and immediately return to the setting
you want after the timer delay.
The CC Ease panel has an integrated type 2 3-position
switch. Next to the standard 3 ventilation settings the
CC Ease panel also has an additional ventilation setting:
•PositionA Absent
- Use when house is unoccupied.
At setting A, the house is ventilated using the mi-
nimum prescribed ventilation volume.
If multiple position switches are available in the
house, the ComfoAir will switch to the highest
ventilation setting unless overruled by an auto-
mated software programme.
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ttedinthebathroomtoextractanyexcessmois-
ture after showering, as soon as possible. The bathroom
switches vary widely in model and are therefore not il-
lustrated here. If required, the bathroom switch can be
turned on and off using a time delay entered via a digital
operating device.
Delay timer
This ensures that the ComfoAir does not switch on at the
highestsettingwhenactivated,butrst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). In that
case, leave the delay timer at 0.
Overrun timer
This ensures that the ComfoAir does not switch back to
the normal (or previous) setting when deactivated, but
rstwaitsfortheoverruntimertorunitscourse.Once
the programmed overrun timer is complete, the ComfoAir
returns to the normal (or previous) ventilation setting.
If the bathroom switch is turned off within the
programmed delay timer period, then the over-
run function will be terminated.
Light switch
The functions of the bathroom switch can also be inte-
grated into a light switch.
2.2.4 CO2-Sensor
The ComfoAir Luxe can also be operated using a CO2
sensor. A CO2sensor measures the CO2levels in the room
where it is placed. When the CO2sensor is set on ‘auto-
matic’ the CO2sensor will control the ventilation setting
according to the ventilation need in the room. When the
CO2levels are high the ventilation setting will automati-
cally increase. When the CO2levels are low the ventilation
setting will automatically decrease. It is also possible to
use the CO2sensor as a standard 3-position switch. The
CO2levels in the room will then by ignored.

illustrated below.
2.2.5 CC Ease panel
The ComfoAir Luxe can be operated by means of a CC
Ease panel, which can be ordered separately.
The CC (Comfort Control) Ease panel is a digital operat-
ing 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.
