2.1.9 Geothermal heat exchanger (optional)
It is possible to fi t the ventilation system with a geo-
thermal heat exchanger. The geothermal heat ex-
changer ensures that outside air is supplied to the
dwelling at a constant temperature of about 8 °C.
Therefore, in the event of subzero temperatures, the
outside air can be heated up by means of the geo-
thermal heat exchanger, prior to releasing it into the
house via the ComfoAir. Alternatively, in the event
of hot summer conditions, the outside air can be
cooled down by means of the geothermal heat ex-
changer, prior to releasing it into the house via the
ComfoAir. The geothermal heat exchanger is auto-
mated.
The geothermal heat exchanger is part of the
ducting of the ventilation system, and does
not form part of the ComfoAir.
2.1.10 Enthalpy (optional)
The ComfoAir can be optionally fi tted with an en-
thalpy exchanger. An enthalpy exchanger is less
sensitive to freezing. An enthalpy system means the
ComfoAir uses the afterheater less, and no longer
reduces the air supply from outside, though it does
stop it in extreme cold.
2.1.11 Luxury version extra options
Besides the options stated earlier, the ComfoAir
Luxe also offers the following options:
•
Connection for remote (fi xed-line) malfunction
alerts;
• Connection for remote (fi xed-line) deactivation
of the fans;
• Connection for fi lter alert for external fi lters.
2.2 Available operating devices
The ComfoAir can be fi tted with the following
operating elements:
• 3-position
switch;
• Wireless 3-position switch;
• 3-position switch with malfunction indicators;
• Bathroom switch to temporarily select the
highest ventilation position;
• CO
2
sensor;
• CC Luxe panel;
• CC Ease panel.
A concise explanation of these operating elements
is given in the paragraphs below.
2.2.1 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 fi tted in the house (e.g.
in the kitchen). The following types of switches can
be used:
• Type 1
J
Standard 3-position switch;
• Type 2
J
3-position switch with LED
for malfunction and fi lter alerts;
• Type 3
J
Wireless 3-position switch with:
LED for malfunction and fi lter indication.
If multiple position switches are available in
the house, the ComfoAir will switch to the
highest ventilation setting unless overruled by
an automated software 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.

The CC Ease panel or CC Luxe panel can be
used to select an additional ventilation posi-
tion (the absent setting).
2.2.2 CO
2
sensor
The ComfoAir can also be operated using a CO
2
sensor. A CO
2
sensor can be used either as a 3-po-
sition switch or to determine manually the ventila-
tion required by measuring CO
2
levels in the room
concerned.
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 fi tted in the bathroom to extract any
excess moisture after showering, as soon as pos-
sible. 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 an digital operating device.
Delay timer
This ensures that the ComfoAir does not switch on
at the highest setting when activated, but fi 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).
