Adjusting heating curves
The heating curves represent the relationship between the outdoor temperature and the boiler water or supply temperature.
Put simply: The lower the outdoor temperature, the higher the boiler water temperature. In turn, the room temperature is
dependent on the boiler water temperature.
Factory settings:
Slope n = 1.4
Shift N = 0
The slope of the heating curve is normally within the range
marked;
A for underfloor heating systems
B for modulating heating systems
C for heating systems with boiler water temperatures
over 75°C / 167°F
