Menu 1.9.6 - fan return time
speed 1-4
Setting range: 1 – 99 h
Default value: 4 h
Here you select the return time for temporary speed
change (speed 1-4) on the ventilation in menu 1.2.
Return time is the time it takes before ventilation speed
returns to normal.
Menu 1.9.7 - own curve
supply temperature
heating
Setting range: 0 – 80 °C
You can create your own heating curve here, if there
are special requirements, by setting the desired supply
temperatures for different outdoor temperatures.
Caution
Curve 0 in menu 1.9.1 must be selected for
own curve to apply.
Menu 1.9.8 - point offset
outdoor temp. point
Setting range: -40 – 30 °C
Default value: 0 °C
change in curve
Setting range: -10 – 10 °C
Default value: 0 °C
Select a change in the heating curve at a certain out-
door temperature here. One step is usually enough to
change the room temperature by one degree, but in
some cases several steps may be required.
The heat curve is affected at ± 5 °C from set outdoor
temp. point.
It is important that the correct heating curve is selected
so that the room temperature is experienced as even.
TIP
If it is cold in the house, at, for example -2 °C,
"outdoor temp. point" is set to "-2" and
"change in curve" is increased until the desired
room temperature is maintained.
Caution
Wait 24 hours before making a new setting,
so that the room temperature has time to
stabilise.

Menu 1.9.9 - night cooling
start temp. exhaust air
Setting range: 20 – 30 °C
Default value: 25 °C
min diff. outdoor-exhaust
Setting range: 3 – 10 °C
Default value: 6 °C
Activate night cooling here.
When the temperature in the house is high and the
outdoor temperature is lower, a cooling effect can be
obtained by forcing the ventilation.
If the temperature difference between the exhaust air
and the outdoor air temperature is greater than the
set value ("min diff. outdoor-exhaust") and the exhaust
air temperature is higher than the set value ("start
temp. exhaust air") run the ventilation at speed 4 until
one of the conditions is no longer met.
Caution
Night cooling can only be activated when
house heating has been deactivated. This is
done in menu 4.2.
