slope of the heating characteristic curve
The characteristic is used to control the heat dissipation of the heating circuit
as a function of the outdoor temperature. The following diagram shows
the effect of the selected characteristic slope on the calculated reference
fl
ow temperature of the heating circuit. The correct characteristic is de
fi
ned
by the intersection of the calculated maximum
fl
ow temperature (design
temperature) with the minimum outdoor temperature.
Example: Design temperature of the heater 60°C. Flow at lowest outdoor
temperature according to heating demand calculation -12°C.
The intersection produces a slope of 1.2 as the setting value.
Setting range: from 0.0 to 2.5 / default setting: 0.8

The following settings can be used for parallel translation of the
characteristic for certain time periods such as daytime and night-
time mode.
The calculated reference
fl
ow temperature is limited in the upwards
direction by the setting for the maximum heating circuit temperature
(11.3).
