This function avoids the formation of the legionella
bacterium wich ,sometimes develops in pipes and water
tanks where the temperature is included between 20
and 40°C. If the storage temperature remains more than
100 hours less than 59°C and the function is enable, the
boiler is light aan and the storage water is warmed up to
65°C during 30 minutes.

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.
