Setting the heating curve slope or level too high or too

For technically-minded system users
■
Heating curves illustrate the relationship between the
outside temperature and the flow temperature. Sim-
plified: The lower the outside temperature, the higher
the flow temperature.
The illustrated heating curves apply with the following
settings:
■
Heating curve level = 0
A different setting for the level will shift the curve in
parallel in a vertical direction.
■
Standard room temperature = approx. 20 °C
In the delivered condition, the slope is set to 1.4; the
level to 0.
