Description
5 2 3 Parallel curve shift Zone 2 Off set
To adapt the heating curve to the system requirements, shift the curve in parallel so that the calculated fl ow temperature
is modifi ed, in addition to the room temperature.
By accessing this parameter and turning knob "5" (Figs 1 and 2 - page 4), the curve can be shifted in a parallel manner.
The value is indicated on the display, from -20 to +20.
