sensor;

• 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 ventilation
positions of the ComfoAir. One or multiple 3-position
switches can be fitted in the house (e.g. in the kitch-
en). The following types of switches can be used:
• Type 1
Standard 3-position switch;
• Type 2
3-position switch with malfunction and
filter alerts indicator;
• Type 3
Wireless 3-position switch (RF)
• Type 4
Wireless 3-position switch (RF) with
malfunction and filter alerts indicator;
• Type 5
3-position switch integrated on a
motor free extractor hood.
An wireless 3-position switch need to be
retuned to the ComfoAir if a General Reset
is given.

Setting the ventilation using
3-position switch(es)
A 3-position switch can be used to set 3 different ven-
tilation positions.
• Position 1
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 an seperated
button for the Timer. After the timer delay the Com-
foAir 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 and CC Luxe panel have an inte-
grated type 2 3-position switch. Next to the standard
3 ventilation settings the CC Ease panel and CC
Luxe panel also have an additional ventilation set-
ting:
• Position A
Absent
- Use when absent.
At setting A, the house is ventilated using the
minimum 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 automated software programme.
2.2.2 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 operating device.
delay timer
This ensures that the ComfoAir does not switch on at
the highest setting when activated, but first 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 first waits for the overrun timer to run its course.
Once the programmed overrun timer is complete, the
ComfoAir returns to the normal (or previous) ventila-
tion setting.
If the bathroom switch is turned off within
the programmed delay timer period, then the
overrun function will be terminated.
