Test model for the heating curve
Information
Example that demonstrates the use of the hot water temperature reset
for a heating system.
The parameters of the block heaCur
are for a heating system with
60°C supply water temperature and
40°C return water temperature at
an outside temperature of
-10°C and a room temperature of
20°C. The offset for the temperature reset is
8 Kelvin, i.e., above
12°C outside temperature, there is no heating load.
The figure below shows the computed supply and return water temperatures.
