A Slope: Slope of the heating curve:
B Max: Maximum temperature of the heating circuit
C Base: Ambient temperature setpoint
D xx°C ; xx Relationship between the heating circuit flow
°C temperature and the outdoor temperature. This
information is visible throughout the slope.

Screed drying

The screed drying function is used to force a constant flow temperature or
a series of successive temperature levels to accelerate screed drying on
underfloor heating.
Floor heating circuit: slope between 0.4 and 0.7
Radiator circuit: slope at approximately 1.5
