By pressing the “SET” key again on the parameter to be
modified, its value can be modified using the “+” and “-” keys.
Then press the “SET” key to confirm (a beep will confirm
the modification) and the “ON/OFF” key to exit the menu.
If parameter G01=1 is set (smartgrid enabled), the EVU and pho-
tovoltaic functions are not available. To enable them, set para-
meter G01=0 (smartgrid not enabled).
To enable the Smart Grid function, select the G01 value, pressing the
“SET” key again the value “0” will appear.
To activate the mode, use the “+” and “-” keys to bring the value to
“1”.
When G01=1 is set, the water heater will work only in SMART GRID
mode.
When the SMART GRID function is enabled, the symbol appe-
ars

2.8.11 AL menu - Anti-Legionella
From this menu it is possible to enable and disable the ANTI-
LEGIONELLA function and set the parameters for its cor-
rect functioning.
To limit the risk of legionella spreading, the water heater is in fact
equipped with a function, called ANTI-LEGIONELLA, which, if
enabled, allows automatic disinfection cycles to be carried out,
bringing the water temperature inside the tank through a cycle
of water heating at 62°C (changeable default value), activating
the heat pump and the electrical heater and keeping them for
30 minutes (changeable default value), ensuring the elimina-
tion of any bacteria present.
This feature is normally set up to activate autonomously every
14 days (changeable default value) and to activate after mid-
night on the fourteenth day.
ATTENTION : the 14-day waiting time cycle may not even be
respected because if, during normal operation, the temperature
of the water inside the tank already reaches 62°C for a mini-
mum time of 30 minutes, the waiting time is reset.
NOTE : If after its activation, the ANTI-LEGIONELLA function
fails to satisfy the temperature conditions defined by parameter
h02 for a minimum time defined by parameter h06, and after
the time defined by parameter h05, the function will be suspen-
ded and the unit will to work under normal conditions. In the
latter case the alarm “E80” will be displayed to indicate to the
user that the ANTI-LEGIONELLA cycle has not been comple-
ted correctly.
The cycle will be performed again after the period defined by
parameter h04.

Parameters:
h01: from this parameter it is possible to enable or disable the
ANTI-LEGIONELLA function:
h02 : when the function is enabled and active, this parameter
represents the temperature that the water inside the tank must
reach to guarantee the elimination of any bacteria present in it
h03 : when the function is enabled and active, once the tempe-
rature h02 is reached, this parameter represents the maximum
delta within which the water temperature must remain to ensu-
re that the ANTI-LEGIONELLA function takes effect.
h04 : parameter representing the time interval, expressed in
number of days, between two ANTI-LEGIONELLA cycles
h05 : parameter which represents the maximum duration of an
ANTI-LEGIONELLA cycle
h06
: when the function is enabled and active, once the tem-
perature h02 has been reached, this parameter represents the
minimum time in which the water temperature must remain in
order to ensure that the ANTI-LEGIONELLA function takes ef-
fect.
When the ANTI-LEGIONELLA function is enabled, the symbol
appears on the display according to the following logic:
