Parallel curve shift
Zone 2 Off set
from - 20 to + 20
0
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.

If setted = 0 the room temperature doesn’t infl uence the calculation of the set-point.
If setted = 20, the room temperature has the maximun infl uence to calculate the set-
