Heating curves
The adjustment of the heating curve is dependent of the
plant installation and shows the relation between the outside
temperature and the heating water temperature.
Recommended setting values:
The calculation of the required heating energy is based on
the coldest avarage outdoor temperature and can be reque-
sted from the heating specialist.
