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.

To adapt the heating curve to the system require-
ments, shift the curve in parallel so that the calcula-
ted
fl
ow temperature is modi
fi
ed, in addition to the
room temperature.
By accessing the parameter and pressing the
button
b
, 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
fl
ow temperature with respect to the set-point
