If the cursor is placed on Growth curve temperature, Growth curve minimum or Growth curve
maximum and you push the confirmation key the curve for the settings concerned will be displayed. You may
change the curve settings or switch off the curve. Press the cancel key to return to the previous window. If you
have switched off the curve, the text 'growth curve' will be replaced by the standard text and you can no longer
access the relevant curve settings from this window (the curve is off).
START FAN 2 / FAN 3
If the main ventilation consists of more ventilation controls, you have to set the percentage at which the 2
nd
/
3
rd
ventilation control have to be switched on (switch-on percentage relative to the total capacity of the
controlled ventilation group) behind “Start fan 2” and/or “Start fan 3”.
The entry behind ”Proportional” ”Step” shows the number of the ventilation control which is currently switched
on (1 = 1
st
ventilation control, 2 = 1
st
and 2
nd
ventilation control, 3 = 1
st
, 2
nd
and 3
rd
ventilation control)
”Step”: step of the step control which is currently switched on.
If the capacity of the controlled ventilation group (compared to the total capacity) is less than the percentage
entered behind “Minimum ventilation”, the controlled group is always fully on.
AQC FLAP
Adjusting the control characteristic is only possible for an AQC flap without a measuring fan. If there is a
measuring fan in the controlled ventilation group, menu option “2 AQC flap” will not be displayed.

The ventilation groups
“
Left/Right/Front/Middle/Rear/
Recirculation/Top
and
Bottom
” are
identical as regards their settings and
they are all set in a similar manner. A
ventilation group can consist of a
maximum of 3 separate controls (flaps).
The temperature setting, bandwidth and
minimum and maximum ventilation then
apply to all three the controls (1, 2 and
3).
TEMPERATURE SETTING
The temperature on the basis of which the ventilation group controls; this setting is always relative to the house
temperature. The calculated temperature on the basis of which the ventilation group controls is shown behind
the temperature setting.
BANDWIDTH
The bandwidth determines the 'sensitivity' of the control. A short bandwidth will cause the control to react to a
rise in temperature very quickly. This is not good for the climate in the house, since it will result in too many
ventilation variations. That is why a bandwidth of 4 to 7°C, depending on the outside temperature, is to be
advised (also see 'Automatic bandwidth compensation' on page 18).
MINIMUM AND MAXIMUM VENTILATION
The minimum and maximum flap opening can be set here.
CURRENT TEMPERATURE
This line shows the current temperature on the basis of which the ventilation group is controlling.
