5.1.2.6 "Heating curve" key
Determines the heating curve for the heating circuits (diagram, see detailed
description in chapter "Controller functions")
The slope of the heating characteristic describes the relation between the change in
the flow temperature and the change in the outside temperature. In case of large
heating surfaces (and therefore low flow temperatures) like floor heating systems,
the heating characteristic curve is less steep compared to smaller heating surfaces
(e. g. radiators).
The setting value refers to the lowest outside temperature used for heat demand
calculation.
CAUTION This parameter is to be set by the heating technician and should not be altered
afterwards.
