Each circuit is controlled by its own heat curve. The
installer sets the type of heating for each circuit, that is
Radiatoror Underfloor. The curve for Underfloorhas
lower values because the floors do not tolerate such
high temperatures.
Fig. 51 Radiator
The images display the factory setting curve for radiator
circuit. At -2.5 °C the flow set point is 37.4 °C.
Fig. 52 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
temperature degree.
The value at 0 °C is displayed above the curve's left-hand
part, factory value 35.7 °C.

Change the left point:
B Press the menu dial when the square is marked.
The value is marked.

B Turn the menu dial to change the value. Press the dial
to save or use to return without saving.
In the window, the square is marked again and any
changed values are displayed after the square. In
addition, the curve is updated according to the new
value.
Change the right point:
B Turn the menu dial when the square is marked. The
upper square is changed to outdoor temperature with
the corresponding curve value after the colon. The
circle marks the relevant curve position.
B Continue to turn the dial until it shows a square
before the colon.
B Press the dial to mark the value.
