P11: ANTI-LEGIONELLA
Through this parameter you can enable or disable the Anti-
legionella function.
The anti-Legionella (function activated by default) consists
of a boiler’s water heating cycle at 65°C every 30 days for
5 minutes (in order to carry out thermal disinfection action
against the related bacteria) only in case the water in the
tank has not been driven at least once at 65°C for 5 minutes
without interruptions.
The 30-day counter is reset whenever the water temperature
in the boiler reaches 65°C at least for 5 minutes.
If the water, during the heating cycle in the boiler, does
not reach 65°C for 5 minutes within one hour, the control
unit emits an acoustic signal and the display shows, on the
hydraulic diagram, the icon of a ashing boiler. In this alarm
situation, the control unit forces the water heating in the
boiler and if that succeeds automatically resets the alarm.
Otherwise, after entering the parameter P16 “LEG” select
the sub-parameter “RS L”; the control unit exits from the
alarm condition resetting the 30-day counter.
The Anti-Legionella function can be enabled only for hydraulic
schemes which provide additional heating:
diagrams 02 - 04 - 05 (selectable in the installer parameter
P1).
