Description
Value of the heating curve gradient.
underfloor heating circuit: gradient between 0.4 and 0.7
radiator circuit: gradient of approx. 1.5
Maximum temperature of the circuit
Curve base point temperature (default value: Off = auto

If Base: Off, the curve base point temperature becomes
equal to the room set point temperature
Water temperature in the circuit for an outdoor tempera
