This menu is available only if a DHW heat pump is installed. For
further information, see the product manual.
– "Operating mode": sets the DHW production mode.
– "Quiet mode activation HPWH" refer to the
paragraph “Heat Pump”. For DHW heat pumps you can
only activate the function. You cannot set a start and
end time.

"Operating mode":
– "Green": the heating elements are excluded from the
production of domestic hot water and are activated
only in case of a heat pump malfunction.
– "Comfort": domestic hot water is produced using both
the heat pump and the heating elements.
– "Fast": domestic hot water is produced by using both
the heat pump and the heating elements at the same
time. The heating elements are switched on together
with the heat pump to minimise the DHW storage tank
charge time.
– "I-memory": an algorithm optimises domestic hot
water production according to the user’s habits.
– "HC - HP": the production of domestic hot water
follows the settings of the EDF signal. To configure the
EDF signal of the heat pump, see the product manual.
3.11.8 Photovoltaic integration
This menu is available for products that are configured for
integration with a photovoltaic system (heating/cooling,
hybrid, DHW heat pumps).
– "Photovoltaic integration": sets the use of the DHW
storage tank heating element for supported heat pumps
(see the product manual for further information).
– "None"
– “Photovoltaic integration”: activates the
heating element of the DHW storage tank (also
simultaneously to heating or cooling) when
additional electrical energy is available from the
photovoltaic system.
– "PV offset DHW setpoint temperature": if a heating
heat pump or a hybrid system is installed, the parameter
sets the degrees to be added to the temperature set-
point for DHW storage tank charge when additional
electrical energy is available from the photovoltaic
system.
– "PV setpoint temperature": if a DHW heat pump is
installed, the parameter sets the temperature set-point
for DHW storage tank charge when additional electrical
energy is available from the photovoltaic system.
