Heating curve
Heat pump's controller is responsible for maintaining proper temperature in central
heating installation depending on the outside temperature. While the temperature
outside the facility is low, heat demand within the facility is higher, whereas while
the temperature outside is high, analogically, there’s no need to maintain high
temperature within the installation. Correlation between outside temperature and
heating installation’s temperature can be presented in a graphical form of so called
heating curve. The diagram below presents a compilation of heating curves for the
set point of room temperature characteristics, climate zone, and the type of heating
installation one must select appropriate heating curve.
In case of the need to offset the heating curve, it is necessary to change the parameter
[heating curve]. The diagram below presents heating curve no. 8 with the offset -10°C
and 10°C.
