Selecting the set room temperature

Individually adjustable for each heating

circuit.

The heating curve is offset along the axis

of the set room temperature. When the

heating circuit pump logic function has

been enabled, the curve modifies the

starting and stopping characteristics of

the heating circuit pump.
