Adjusting the heating curves
The heating curves illustrate the relationship between the outside temperature and
the boiler water or flow temperature.
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 temperature.
