NOTE : When enabled and active, this feature takes priority
over the PV feature.
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.
When the EVU function is enabled, the symbol appears on
the display according to the following logic:

2.8.9.2 Photovoltaic parameters (photovoltaic functionality)
(see also “6.8.1 Remote connections”)
In this configuration it will be possible to exploit the excess
energy produced by the photovoltaic system to produce and
store domestic hot water at a temperature equal to the pre-
viously set setpoint value , plus an offset.
To set the parameters, access the phv menu by pressing the
“SET” key on the parameters “P03” and “P04”.

modification) and the “ON/OFF” key to exit the menu.
With the photovoltaic function active (P01 set to 1), the heat
pump and the electrical heater will be activated simultaneously
until the set-point set for this mode is reached. The setpoint is
defined by the PV offset parameter (parameter P02) which de-
fines by how much to increase the standard setpoint with active
photovoltaic.
For example, if the offset is equal to 20°C and the setpoint =
50°C the setpoint will be 50+20=70°C. In any case, by default
the maximum setpoint is 75°C, therefore if offset=30°C and
setpoint=50°C the photovoltaic setpoint will not be 50+30=80
but 75°C.
When the PHOTOVOLTAIC function is enabled, the symbol ap-
pears on the display according to the following logic:
Behavior Description Active mode

steady light
PHOTOVOLTAIC enabled

The unit continues to work in the mode

The unit will be put in the BOOSTER
status and the setpoint will be raised
by an offset (the setpoint cannot in any
case exceed 75°C)
2.8.10 SG MENU - Smart Grid functionality (see also “6.8.1
Remote connections”)
The water heater is designed to be integrated with an intelligent
electricity network (SMART GRID), managing it efficiently. The
electronics of the unit, in fact, provides two digital inputs for ma-
naging this function and, depending on their condition, decides
how the water heater must work, distinguishing between four
possible operating states:
• Operating state 1: in this operating state the unit is put
into OFF mode and its duration can be a maximum of 2
consecutive hours for a maximum of three times a day.
If these conditions are not respected, the electronics will
change the operating state bringing it to operating state 2.
• Operating state 2 : in this state, to obtain maximum effi-
ciency, the unit will work in ECO mode.
• Operating State 3 : You enter this state when you have the
opportunity to take advantage of some excess energy. In
this state, in fact, the unit is made to work in BOOSTER
mode by raising the setpoint by a pre-set value (offset) up
to a maximum of 75 °C. In this mode, the water heater will
reach a DHW storage temperature equal to the previously
set setpoint value, plus an offset (defined by parameter
G02). For example, if the offset is equal to 20°C and the
setpoint = 50°C the setpoint will be 50+20=70°C. In any
case, by default the maximum setpoint is 75°C, therefore
if offset=30°C and setpoint=50°C the setpoint will not be
50+30=80 but 75°C.
• Operating state 4: when there is a lot of excess energy,
the electronics will use the moment to make the water he-
ater work in BOOSTER mode with a fixed setpoint of 75°C
(max setpoint).
To set the parameters it is necessary to access the SG menu,
by pressing the “SET” key the values “G01” and “G02” will
appear.
