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:
• Balancedventilation;
• Heatrecovery;
• Bypassforfreecooling;
• Frostprotection;
• Openreprogramme;
• Wireless(RF)control(optional)
• Enthalpy(optional);
• Analogueinput(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
thedoorsensureagoodthrough-owofairinthedwell-
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);
• Ductsystemforthesupplyofoutdoorair(B)andthe
exhaustofindoorair(C);
•
Supplyvalvesinthelivingroomandbedrooms(D);
• Exhaustvalvesinthekitchen,bathroom,thetoilet
and (if present) the storage room (E).
2.1.2 Heat recovery
Besides ensuring a healthy balance between incoming
andoutgoingair,theComfoAiralsoprovidesthebenets
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
TheComfoAirisalsottedwithafrostprotectiondevice.
This is an automatic protective system that temporarily
reduces(orevenbrieystops)thesupplyofoutdoorairto
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 Openreprogramme
TheComfoAiristtedwithanOpenreprogramme.The
Openreprogrammeisusedinhousesthathaveare-
place, as there is a risk of air being sucked back from the
chimney.TheOpenreprogrammeworksautomatically
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)
TheComfoAirLuxeisttedwithoneinput(0-10V).This
input can be used to connect a sensor or control
system to the ComfoAir. Examples of the options include:
• CO2sensor;owregulationusingcarbondioxide
levels;
• Moisturesensor;owregulationusingmoisturele-
vels;
2.2 Available operating devices
The ComfoAir is tted with the following operating de-
vices:
• Displayontheunit;
• 3-positionswitch;
• 3-positionswitchwithmalfunctionindicator;
• Wireless3-positionswitch;
• Wireless3-positionswitchwithmalfunctionindica-
tor;
• Bathroomswitchtotemporarilyselectthehighest

Setting the ventilation using
3-position switch(es)
A 3-position switch can be used to set 3 different ventila-
tion positions.
• Position1gLow.
- Use for low ventilation levels.
• Position2Normal.
- Use when present and no extra
ventilation is needed.
• Position3High.
- Use during cooking, showering
and when additional ventilation is
needed.
• TimerTemporary 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:
•PositionA 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
mostlyttedinthebathroomtoextractanyexcessmois-
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
highestsettingwhenactivated,butrstwaitsforthedelay
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
rstwaitsfortheoverruntimertorunitscourse.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.

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.

regulates the required ventilation volume automatically
according to a preset personal ventilation programme.
During automatic ventilation mode “AUTO” will be dis-
played on the CC Ease panel.
In addition to showing the programmed ventilation set-
ting, the CC Ease panel also displays whether a tempo-
rary control system (such as a CO2sensor or a bathroom
switch) is overriding the ventilation setting.
In the event a required ventilation setting is being over-
ridden by a time delay function (such as the bathroom
switch overrun timer). a 't' is displayed in the bottom
right-hand corner of the CC Ease panel.
In the event a required ventilation setting is being over-
ridden by a signal from a sensor (such as a CO2sensor),
an 'A' is displayed in the bottom right-hand corner of the
CC Ease panel.

2.4 Maintenance by the user
The following maintenance must be carried out by the
user:
• Replacingthelters;
• Cleaningthevalves(inthedwelling).
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 per-
formance of the ventilation system.
2.4.1 Replacingthelters
If so indicated on the digital operating device, the l-
ters must be cleaned or replaced.
Replace the lters (at least) once every six
months.
• On the display the message “FiL” and ”tEr” will ap-
pear alternately.
• On the CC Ease panel "FilterI" will appear.
Toreplace...
1. Press “ OK ” on the display or press " " on the
CC Ease panel for at least 4 seconds until the lter
alert disappears.
2. Disconnect the power from the ComfoAir.
3. Remove the lter caps (A) from the ComfoAir.
4. Remove the old lters (B) from the ComfoAir
5. Slide the new lters back into the ComfoAir.
6. Ret the lter caps (A) to the ComfoAir.
7. Reconnect the power to the ComfoAir.

2.4.2 Cleaning the valves (in your dwelling)
The ventilation system may be tted with the following
valves:
Exhaust valve (STB) Exhaust valve (STC)
Exhaust valve (STV) Exhaust valve (STK) Supply valve (STH)
Exhaust valve (STB) Exhaust valve (STC)
Exhaust valve (STV) Exhaust valve (STK)
Supply valve (STH)
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:
1. Markthesettingofthevalve;
2. Removethevalvefromthewallorceiling;
3.
Cleanthevalveinasolutionofsoapandwarmwater;
4. Rinsethevalvethoroughlyandwipedry;
5. Place the valve back WITH EXACTLY THE SAME
SETTING(andINTHESAMEHOLE);
6. Repeat this procedure for the other valves.
About the valve settings...
The ventilation air is supplied and discharged by means
of valves. Gaps near doors in the dwelling ensure that the
airowsintherightdirection.Inordertoensurethatthe
correct ventilation volumes are maintained in the rooms,
the following must be observed:
• Do notsealthegaps;
• Do notchangethesettingsofthevalves;
• Do not swop the valves.
EN - 14
The installer will have set all the valves to ensure the op-
timum 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 ex-
actly the same ventilation hole in the wall or
ceiling) AT ALL TIMES. Otherwise, system per-
formance will be compromised.
2.5 Malfunctions
Malfunctions in the ComfoAir are reported as follows:
• Themalfunctionalertappearsonthedisplay,
• ThemalfunctionalertappearsontheCCEasepanel;
• Themalfunctionindicatoronthe3-positionswitch
lights up.
A concise explanation of methods of reporting malfunc-
tions is given in the paragraphs below.
2.5.1 Malfunction alerts on the digital operating
device
In the event of a malfunction, the corresponding malfunc-
tion code will be displayed on the digital operating device
of the ComfoAir.
2.5.2 3-position switch with malfunction
indicators
The3-positionswitchesthatarettedwithamalfunction
indicatorshowwhenamalfunctionorlterdirtyalerthas
occurred. Depending on the type of the 3-position switch,
this is done in one of the following two ways:
• 3-positionswitchwithmalfunctionindicator.

• Wireless3-positionswitchwithmalfunctionindica-
tor.
The malfunction indicators will light up once this
3-position switch is used. One indicator will light up
green to indicate communication has been estab-
lished. Subsequently, in the event of a malfunction or
lterdirtyalertbothindicatorswillashred3times.
After that, both indicators will light up green once
more.
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.
Thisisgivenontheidenticationplateonthetopofthe
ComfoAir. The system should not be disconnected from
the power supply, unless the ComfoAir must be taken out
ofserviceduetoaseriousmalfunction,orforlterclean-
ing/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 moi-
sture and results in problems with mould. Long-
term deactivation of the ComfoAir must there-
fore be prevented.
Condensation may form on the outside of the
ComfoAir if the unit is fitted in a space with hi-
gher average humidity levels (such as a ba-
throom, shower, toilet or kitchen). This is not a
problem for the ComfoAir.
2.6 End of useful life
Consult with the supplier about what should be
done with the ComfoAir at the end of its useful life. If the
ComfoAir cannot be returned to the supplier, avoid dis-
posing of it with the domestic waste, and ask your local
council about the options for recycling the components
or processing the materials in an environmentally friendly
manner.
Furthermore, do not dispose of batteries from the wi-
reless (RF) switches with the normal waste, but bring
them to the specially designated disposal locations.
