Slope setting ranges:
■
Underfloor heating systems: 0.2 to 0.8
■
Low temperature heating systems: 0.8 to 1.6
Selecting the set room temperature
Individually adjustable for each heating circuit.
The heating curve is offset along the axis of the set
room temperature. With the heating circuit pump logic
function enabled, the curve modifies the starting and
stopping characteristics of the heating circuit pump.
