Setting of heat curve

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.

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).
