To adapt the heating curve to the system requirements,
shift the curve in parallel so that the calculated ow
temperature is modi ed, in addition to the room tempe-
rature.
By accessing the parameter and turning the encoder,
it is possible to shift the curve in a parallel direction.
The shifting value can be read on the display: from -14
to +14 for high-temperature devices, or from -7 to 7 for
low-temperature devices. Each step corresponds to a 1°C
increase/decrease In the ow temperature with respect to
the set-point value.

Only enabled when an outdoor sensor is installed
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 below
may be chosen.
