Description
4 2 3 Parallel curve shift Zone 1 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.

When an outdoor sensor is used, the boiler calculates the most suitable delivery
temperature, taking into account the outside temperature and type of system.
The type of curve should be selected in correspondence with the projected
temperature of the system and the nature of the dispersions present in the
structure. For high-temperature systems, one of the curves depicted in the chart
may be chosen.
1.0 - 1.5 = Standard System
2.0 - 3.5 = Convector Radiators
Note: The Outdoor Sensor should only be used when the boiler is used for central heating only.
