Heating curve

Determines the heating curve for the heating circuits.
The heating curve describes the relationship of the flow
temperature change to the outside temperature change. With a
larger heating surface, such as with floor heaters, the heating
curve has a less extreme slope than with a smaller heating

surface (e.g. radiators).
The set value refers to the lowest outside temperature used for
heat demand calculation.
ATTENTION
This parameter must be set by the technician and should no
longer be changed.

► Press input button
The slope of the heating curve appears at the bottom left-hand
side of the display.
► Set the flashing heating curve value by turning the input button

(design temperature also flashes and is changed
automatically depending on the slope of the heating curve).
► Confirm by pressing the input button
Alternative: Automatic acceptance of the value after the set
information time (see 5.1.2.7 "System information" button, pg. 35).
