6.4.5. HEATING CURVE HC1
T
B9
– Outside temperature
T
B1
– Flow temperature
After clicking on the line Heating curve HC1 it is possible to enter the menu where all parameters
concerning the weather-compensated curve HC1 can be set. It defines two limits of the outside
temperature (Outside temperature B9 - point 1 and Outside temperature B9 - point 2), to which
the required temperature of the heated water at the HC1 inlet is assigned (Initial flow
temperature B1 - point 1 and Initial flow temperature B1 - point 2).
The parameter setting of the Outside temperature B9 - point 1 is ranging from -50 to +10°C; the
default value is -12°C.
The parameter setting of the Initial flow temperature B1 - point 1 is ranging from 25 to 85°C; the
default value is 75°C.
The parameter setting of the Outside temperature B9 - point 2 is ranging from 5 to 30°C; the
default value is 15°C.
The parameter setting of the Initial flow temperature B1 - point 2 is ranging from 25 to 85°C; the
default value is 30°C.
The instructions for changing this parameter can be found in chapter 4.
The parameter Curve exponent sets the curvature of the weather-compensated curve according
to the used system of heating (radiator, floor, or convector). This parameter takes the nonlinear
transfer of heat into account. The following table summarizes the values for commonly used
heating systems:
Heat transfer through: Recommended value of the curve
exponent
Floor heating 1.05 – 1.1
Panel radiator 1.26 – 1.33
