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.
