    Your home’s heating installation The House Heating Curve The heating curve is the central part of the product’s control system. It is the heating curve which determines the compensated flow temperature requirements for your property dependent upon the outdoor temperatures. It is important that the heating curve is correctly adjusted, so that you achieve the best operation and economy possible.
  • Page 10 Adjusting the heating curve The method described below can be used to adjust the heating curve correctly. Adjustment if it is too cold indoors • If the outdoor temperature is lower than 0 degrees: Increase the Inclination value by a couple of degrees. Wait 24 hours to see if any further adjustment is required.
  • Page 11 Examples of Heating Curves You can see in the diagram below how the heating curve changes with different Inclination settings. The gradient of the curve shows the temperatures that the radiators require at different outdoor temperatures. Primary Flow Temperature Curve Inclination The inclination value which is set is the primary flow temperature when the outside temperature is –15 °C.
