heating curve no. (p=0)
Boiler'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 equal 22 °C. Depending on the facility characteristics, climate zone, and
the type of heating installation one must select appropriate heating curve.

p- offset of 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. 12 with the offset
-10°C and 10°C.
