Heat curve E21
The flow temperature set points at different outdoor temperatures are automatically calculated using
the values in Basic setting, Æ Chapter 4.3.1 for example on heat curve for radiator systems and
underfloor systems. Values can be changed individually, for example adjusting the heat curve at 0 °C.
