Heating circuit
parameter - Equithermal curve (Heating system temperature exponent)
The parameter allows the equithermal curve (temperature exponent) to be set according to the type
of heating system and the character of the building.
The exponent of the equithermal curve expresses the curve bending and is determined by the type
of heating system (underfloor heating, radiators, convectors).
Recommended setting:
1,0 … 1,3
-
underfloor heating -
heating system with low temperatures, with high inertia
and slow rise of room temperature
1,3 … 2,0 - radiator heating - heating system with medium temperatures and medium
inertia of the system
2,0 … 3,0 - convector heating - with forced airflow (fan-coil saharas) - heating system with
high temperatures and low inertia of the system
INFO -
Correct calculation of the flow temperature to the heating circuit affects the
dimensioning of the heating system and the thermal loss of the object
