Adjusting heating curves (only for weather-compensated

control units)

The heating curves illustrate the rela-

tionship between t he 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.

Settings in the delivered condition:

Slope = 1.4

Level = 0

Generally, the slope of the heating

curve lies

in the range of A for underfloor

heating systems,

in the range of B for low tempera-

ture heating systems (according to

the Energy Savings Order [Ger-

many]).
