Fig. 18 shows the curves for a virtual ambient temperature of 20°C.
Editing parameter P10, the curves shift up or down, respectively, by the same amount.
With a virtual ambient temperature setting of 20°C, for example, if you select the curve corresponding to parameter 1 and the outdoor temperature
is - 4°C, the CH flow temperature will be 50°C.
