Minimum outside temperature (outdoor design)
The minimum outside temperature is the average value of each
of the coldest outside temperatures or recent years, and it has
an influence on the heating curve. The value of the region can
be taken from the required heat load calculation that should be
done for every building, or from the climate zone chart
▶ Set the minimum outside design temperature for the
heating system.
