If On is selected, the heat pump is constantly in winter
operation and heat and hot water are always produced.
Off signifies constant summer operation; only hot water
is produced. Automatic signifies change-over at the set
outdoor temperature.
>>> Outdoor temperature limit for change over
The menu is displayed only if Automatic has been
selected in Winter operation.
>> Maximum operating time for heating at hot water
demand
The menu is not displayed if Block heating during hot
water demandbe set to Yes(Æ Chapter 10.3).
> Circuit 1 Heating
>> Heat curve
The heat curve constitutes the basis for the control
unit's control of the temperature on the heating water to
the circuit and indicates how high it needs to be in
relation to the outdoor temperature. The control unit
increases the temperature of the heating water when the
outdoor temperature drops. The temperature of the
heating water out to the circuit, i.e. the flow temperature
is measured by sensor T1 for circuit 1 (full name E11.T1)
and sensor T1 for circuit 2 (full name E12.T1).
Each circuit is controlled by its own heat curve. The
installer sets the type of heating for each circuit, that is
Radiator or Underfloor. The curve for Underfloor has
lower values because the floors do not tolerate such
high temperatures.
Fig. 20 Radiator
The images display the factory setting curve for radiator
circuit. At -2.5 °C the flow set point is 37.4 °C.
Fig. 21 Underfloor
The images display the factory setting curve for
underfloor circuit. At -2.5 °C the flow set point is
27.2 °C.
Heat curve set for each circuit. If the room temperature
is perceived to be too high or too low in the circuit, it is
preferable to adjust the curve.
The curve can be changed in different ways. The slope of
the curve can be changed by offsetting the flow line
temperature upwards or downwards in the left-hand
(the value at outdoor temperature 20 °C, factory value
22.0 °C) as well as right-hand points (the value at
outdoor temperature -35 °C, factory setting 60.0 °C). In
addition, the curve can be affected by every 5th outdoor

Tab. 10 Change over temperature
In the event of alternation between winter
and summer operation and vice versa, there
is a certain delay aimed at preventing
constant starting and stopping of the
compressor when the outdoor temperature
oscillates around the temperature limit.
