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.
Settings in the delivered condition:
&
Slope = 1.4
