Adjusting the 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 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.
