If you change the slope:
The steepness of the heating curves changes.
B
If you change the level:
The heating curves are shifted in parallel in a verti-
cal direction.
C
If you change the standard room temperature (set
room temperature):
The heating curves are shifted along the "Set room
temperature" axis.
Note
Setting the slope or level too high or too low will not
cause any damage to your heating system.
Both settings affect the level of the flow temperature,
which may then be too low or unnecessarily high.
Heating circuit
A heating circuit is a sealed unvented circuit connect-
ing the heat generator and the radiators, in which the
heating water circulates.
