The radiator exponent is dependent on the type and design of the heating element
and is normally stated by the manufacturer. The radiator exponent describes the
relationship between the increasing supply temperature and the non-proportionally
increasing heat dissipation into the room.
This information is used to calculate the heating curve. The higher this value is, the
more curved the heating curve is.
Start supply temperature curve at outside temperature
Options:
-100…19…100 °C
The outside temperature at which heating is started is specified using this parameter.
This value is the start of the heating curve. The heating limit is dependent on the
insulation standards in the building and can be selected lower, the better the building
is insulated.
