Heating curve
The boiler control unit ensures that the correct
temperature is maintained in the central heating
installation depending on the outside temperature.
When there is a low outside temperature, the heat
demand inside the building is higher. On the other
hand, when there is a high outside temperature, it is
not necessary to maintain a high temperature inside
the installation. The correlation between the outside
temperature and the temperature of the heating
installation can be represented graphically with a
heating curve. The diagram below shows a summary
of the heating curves for a set room temperature of
22 °C. The corresponding heating curve must be
selected according to the building properties, climate
zone and type of heating installation.
If an offset of the heating curve is required, the
parameter [heating curve] must be changed. The
diagram below shows heating curve no. 12 with
an offset of -10 °C and 10 °C.
