Adjusting the heating curves (only for weather-compensated
control)
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.
