How to determine another heat curve, if necessary:
Choose the calculated flow temperature for your system and
the determined min. outdoor temperature for your area.
Pick the heat curve closest to the crossing point of these two
values.
The setting of the desired room temperature has an influence
on the calculated flow temperature (heat curve), no matter if a
room temperature sensor is connected or not.
Whether it is reasonable to change the slope or parallel
displacement will depend on the individual heat requirement.
Small increases or reductions in the heating temperature can be
implemented by means of the parallel displacement.
