in AUTO mode
Level: U=user menu - I=installer menu
Parameters:
H01: from this parameter it is possible to enable or disable the
switching on of the heater when the unit is working in ECO
mode and the compressor cannot switch on due to an inter-
vention of one of its protections (for example intervention of the
HP pressure switch or air temperature at outside the operating
limits):
H02: Difference between the set point and the heater switch-on
temperature
H03 – H04: These parameters are used when the unit is wor-
king in AUTO mode and you want the heater to be turned on
when the water temperature does not rise by a minimum in-
crease (H04) after a given pump operating time of heat (H03).
NOTE: once turned on, the heater will turn off only when the
water temperature reaches the set point
3.9.9 Phv menu - EVU functionality - Photovoltaic functio-
nality
If parameter G01=1 is set (smartgrid enabled), the EVU
and photovoltaic functions are not available. To enable
them, set parameter G01=0 (smartgrid not enabled).
3.9.9.1 EVU functionality (see also "8.8.1 Remote connec-
tions")
This function is indispensable if a subsidized electricity tariff is
subscribed for heat pumps. The aim is to facilitate operation
when the cost of electricity is low, but still having to comply with
the rules of the energy supplier who will be able to decide when
to interrupt the supply.
To meet this requirement, the water heater electronics are fitted
with a digital input which, when opened, allows the unit to be
switched off and thus reduce the load on the electricity grid.
NOTE: When enabled and active, this feature takes priority
over the PV feature.
To set the parameters, access the phv menu, by pressing the
"SET"
key the value "P01" will appear.

3.9.9.2 Photovoltaic parameters (photovoltaic functionality)
(see also "8.8.1 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".

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
