Healthy and comfortable ventilation
Your house has a balanced ventilation system with heat
recovery that supplies the rooms with fresh air. Effec-
tive ventilation is essential for a healthy and comfortable
indoor climate.

Maintenance
Do not remove the plug from the socket
unless indicated by the manual of the
device. This can lead to a build-up of
moisture and mould.
Have the entire system checked and cleaned by a (ser-
vice) engineer at least once every two years.
Carry out maintenance work at least every 6 months ac-
cording to the instructions in the user manual.
Unlock child lock
If you do not use the display on the unit for 15 minutes, it
will automatically return to the main screen and the child
lock will be activated. As long as the child lock is activat-
ed, the symbol is displayed on the main screen. To
unlock the child lock, press and hold the unit's display
for 4 seconds until the symbol is no longer displayed.
Comfort temperature
In summer, the unit uses outdoor air to ensure the in-
door temperature remains as comfortable as possible.
This is similar to opening a window on a cool summer
evening. The unit operates fully automatically based on
the set comfort temperature.
If the indoor air is warmer and the outdoor air cooler
than the set comfort temperature, the cooler outdoor air
is blown into the house without heat recovery.
It is best to set the comfort temperature to the
highest temperature of the thermostat (of the central
heating system). This ensures that the heating and
the ventilation system are well matched. The default
value is 21 °C.
In winter, the unit never blows outside air directly into
the home without heat recovery. Based on the out-
side temperature, the device automatically determines
whether it is summer or winter.

Installation
Safety instructions
■Always comply with the safety regula-
tions in this document. Failure to com-
ply with the safety regulations, instruc-
tions, warnings and comments may lead
to personal injury or damage to the unit.
■Always observe the local building,
safety and installation guidelines of the
municipality, utility companies or other
authorities;
■Always connect air ducts with a mini-
mum length of 900 mm to the unit
before connecting the power supply to
prevent contact with the rotating fans.
■After installation, all parts that could
lead to personal injury are safely out of
reach behind the casing. The ComfoAir
cannot be opened without using tools.
■It is not permitted to modify the unit or
any of the specifications contained in
this document. This may result in per-
sonal injury or reduced ventilation sys-
tem performance.
■Installation, commissioning and main-
tenance must be carried out by a certi-
fied person or company, unless stated
otherwise. If this work is carried out by
unauthorised persons, it may result in
personal injury or reduced performance
of the ventilation system.
■Always unplug the power cord before
starting any work on the unit. Using the
unit with the casing open may result in
personal injury. In this case, make sure
that no conductive or rotating parts can
be touched.
■Static charge can damage the electro-
nics. When working with electronics,
always take protective measures to
prevent electrostatic discharge, such as
wearing an antistatic wristband.
■If the power cord is damaged, it must
be replaced by the manufacturer, the
service engineer or a qualified person to
avoid risks.
Use of the unit
■The unit may only be used once it has
been properly installed according to the
instructions and guidelines given in the
installer manual of the unit;
■Do not open the casing. The installer
makes sure that all components that
can cause personal injury are safely
located behind the casing;
■The unit may be used by: children of 8
years and older; persons with reduced
physical capabilities; persons with
reduced sensory capabilities; persons
with reduced mental capabilities and
persons with lack of experience and
knowledge, as long as they are under
supervision or have received instruction
about the safe use of the unit and are
aware of the hazards involved;
■Children must not play with the unit;
■Children must not clean and maintain
the unit unsupervised.

Connect the unit to the mains power.
Select the language and confirm if the siphon
is assembled the correct way.
See above for installation of siphon.
The unit will now carry out an automatic
selftest. This takes about 4 minutes.

Go to the installer settings.
The fans will follow the preset setting
automaticly and the unit is now in
commissioning mode for 1 hour.

Press to save the value entered and switch
off the commissioning mode.
REPEAT THESE STEPS FOR THE MIDDLE AND
LOW PRESET
Measure the air volumes of each opened valve
using a flow meter.
Write them down.
Set each open valve to the desired air volume for
that room.
Measure again the air volumes of each set valve
using a flow meter.
Check whether the flow is in line with the norm
at each valve.
Everything in order:
Press to switch off the commissioning
mode.
Complete an installation/test report. A sample
installation/test report can be found at the back
of the user manual.
Flows not in line with norm:
Return to step 6.

The fans will automatically start rotating to
the set position. The unit is in the commis-
sioning mode for one hour.

Set the required total air flow to the maxi-
mum flow rate. (MENU>Login>VENTILATION
SETTINGS>HIGH SETTING)
= Air flow almost at limit value
= Air flow insufficient
If the limit value is lower than the desired air
flow, a further system test must be carried out.
(MENU>Login>SYSTEM TEST) For more infor-
mation, see the fitter's manual.
Press to switch the commissioning mode off
again directly without saving the value entered.
Press to save the value entered.
REPEAT THESE STEPS FOR THE MEDIUM AND

Measure the air flow at each opened valve using
a flow meter.
Write down the air flow for these valves.
Adjust the opened valves to the required air flow
per room.
Measure the air flow again at each opened valve
using a flow meter.
Check that the air flow complies with the stand-
ard for each opened valve.

If the air flow is fine everywhere:
Press to exit the commissioning mode.
Complete an installation/test report. An example
can be found in the back of the user manual.
The unit’s installation height must be specified in
the “ALTITUDE” menu.
(MENU>Login>ALTITUDE>)
In the menu BALANCE SETTING an unbalance
between supply and exhaust air can be set.
(MENU>Login>BALANCE SETTING>BALANCE
FINE TUNE)
BALANCE SETTING selection: ‘+’= more ex-
haust air; ‘-’= less exhaust air.
With the FIREPLACE MODE setting activated,
only less exhaust air (=’-’) is possible.
FROST PROTECTION selection (without pre-
heater):
(BALANCE SETTING>FIREPLACE MODE)
■FIREPLACE MODE active? YES: (Default)
Exhaust and supply air remain in balance at all
times. As a result, the unit switches off faster
in frost mode than in inactive fireplace mode.
■FIREPLACE MODE active? NO: There is more
supply air than exhaust air. So in frost mode,
ventilation is maintained longer.
Malfunctions on the preheater or bypass can only be reset after the system test has been carried out again. 3/4
