Heating curves
The heating curves illustrate the
relationship between the outside
temperature and the boiler water or
the 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.
If different room temperatures are
set, the curves will be adjusted
parallel to the set room temperature
axis.
