Adjusting heating curves (only for weather-compensated
control units)
The heating curves illustrate the rela-
tionship between the outside tem-
perature and the boiler water or the
flow temperature. To put it simply: The
lower the outside temperature, the
higher the boiler water or flow tem-
perature. The room temperature,
again, depends on the boiler water or
the flow temperature.
