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 and hold input button î for 3 s.

►Turn the input button î to select the desired heating circuit (HC, MC-1 or MC-2) and confirm it by pressing the input button î. The design temperature (system) appears at the bottom right- hand side of the display.

►Press input button î.

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 î (design temperature also flashes and is changed automatically depending on the slope of the heating curve).

►Confirm by pressing the input button î.

Alternative: Automatic acceptance of the value after the set information time (see 4.1.2.7 "System information" button, pg. 26).
