    For floor heating systems, values between 0.2 and 0.8 are commonly used. Lower values are more suitable for high quality insulation.

    Table below shows resulting set point temperature based on outdoor temperature and angle of the curve:

    E.g. if outdoor temperature is 0ºC and angle of equithermic curve is 0.6, resulting set point temperature is 37ºC.

    doc_tap_Parallel_shift;

    Increases or decreases the curve by defined value.

    E.g. if set point temperature based on angle of curve is 37ºC, and parallel shift is set to 4ºC, resulting set point is 41ºC.
