Adjusting the heating curves
The heating curves illustrate the relation-
ship between the outside temperature
and the boiler water or flow tempera-
ture.
To put it simply: The lower the outside
temperature, the higher the boiler water
or flow temperature. The room temperature, again, depends
on the boiler water or the flow tempera-
ture.
Settings in the delivered condition:
■ Slope = 1.4
■ Level = 0
