  • Page 22: The House Heating Curve

    2. The house heating curve 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 23 Appropriate Default Values During installation you can seldom achieve a precise setting for the heating curve instantly. In this case, the values given below may provide a good starting point. Radiators with small heat-emission surfaces require a higher primary flow temperature. You can adjust the gradient (heating curve gradient) for your heating system under the "Installer / Settings / Radiator system"...
  • Page 24 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.
