Setting of heat curve
If the heat curve has been set too high, the display will
show the message Too high heat curve setting.
▶ Change the heat curve setting.
A heat curve is 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 temperature upwards or downwards
on the left-hand side (the value at outdoor temperature 20 °C, factory
value 22.0 °C) as well as the right-hand side (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 point, factory
value 35.7 °C.

Change the left point:
▶ Press the menu dial when the square is highlighted.
The value is highlighted.

▶ 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 highlighted 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:
▶ Turn the menu dial when the square is highlighted. The upper square
is changed to outdoor temperature with the corresponding curve
value after the colon. The circle highlights the relevant curve position.
▶ Continue to turn the dial until it shows a square before the colon.
▶ Press the dial to highlight the value.

In the window, the square is highlighted again and any changed values
are displayed after the square. In addition, the curve is updated
according to the new value.
Change a specific value, for example the value at an outdoor
temperature of 0 °C:
▶ Turn the menu dial when the square is highlighted until 0 °C is
highlighted ( Figure 51).
▶ Press the dial to highlight the value.

▶ Use
to leave the curve setting window and return to the menu.
Recommendations:
▶ Increase the value of the right point if it feels too cold
at low outdoor temperatures.
▶ Increase the value of curve at 0 °C if it feels a little cold
at outdoor temperatures around 0.
▶ Increase or decrease the value of the curve equally at
the right and left points to fine adjust the heat (the
curve is offset parallel).
