4.1.2.6 "Heating Characteristic" Key
This key makes it possible to set the heating
characteristics for the system’s heating circuits.
The slope of the heating characteristic describes the
relation between the change in the flow temperature with
the change in the outside temperature. In case of large
heating surfaces like floor heating systems the heating
characteristic is less steep compared to smaller heating
surfaces (e.g. radiators).
The set value refers to the lowest outside temperature at
the basis of the heat demand calculation.
IMPORTANT NOTE!
This parameter is to be set by the heating technician and
should not be altered anymore.
