Setting is made separately for each heating circuit.
The room temperature of your heating installation depends to a
great extent on the selection of the right heating curve. If the
selected heating curve is too high, the temperatures in the hea-
ting installation will also be too high, resulting in higher energy
consumption.
If the selected heating curve is too low, the desired temperature
level may only be reached after a while or not reached at all.
