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.
