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
requirements, shift the curve in parallel so that
the calculated ow temperature is modied, 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 ow temperature with respect to
the set-point value.

If setted = 20, the room temperature has the
