Caution
If the stop time is before the start time it means
that the period extends past midnight. Schedul-
ing always starts on the date that the start time
is set for.
A significant change over a longer period of time
may cause poor indoor environment and worse
operating economy.
Menu 1.9 - advanced
Menu advanced has orange text and is intended for the
advanced user. This menu has several sub-menus.
heating curve Setting the heating curve slope.
external adjustment Setting the heat curve offset when
the external contact is connected.
min. flow line temp. Setting minimum permitted flow
line temperature.
room sensor settings Settings regarding the room sensor.
cooling settings Settings for cooling.
fan return time Fan return time settings in the event of
temporary ventilation speed change.
own curve Setting own heat curve.
point offset Setting the offset of the heating curve at a
specific outdoor temperature.

Setting range: 0 - 15
Default value: 9
In the menu heating curve the so-called heating curve
for your house can be viewed. The task of the heating
curve is to give an even indoor temperature, regardless
of the outdoor temperature, and thereby energy efficient
operation. It is from this heating curve that the heat
pump’s control computer determines the temperature of
the water to the heating system, flow line temperature,
and therefore the indoor temperature. You can select
heating curve and read off how the flow line temperature
changes at different outdoor temperatures here.

The slope of the heating curve indicates how many de-
grees the supply temperature is to be increased/reduced
when the outdoor temperature drops/increases. A
steeper slope means a higher supply temperature at a
certain outdoor temperature.
The optimum slope depends on the climate conditions
in your location, if the house has radiators or under floor
heating and how well insulated the house is.
The heating curve is set when the heating installation is
installed, but may need adjusting later. Thereafter the
heating curve should not need further adjustment.
Caution
In the event of making fine adjustments for the
indoor temperature, the heat curve must be
offset up or down instead, this is done in menu
1.1 temperature .

An offset of the heating curve means that the supply
temperature changes as much for all the outdoor temper-
atures, e.g. that a curve offset of +2 steps increases the
supply temperature by 5 °C at all outdoor temperatures.
