Date and time.
Set the day and then confirm. Do the same for
the month, year, hour and minutes.
•
Operation time.
This parameter defines the operating time slots
of the heat pump, of the electrical integration,
and if present, of the hydraulic auxiliary device
according to the hot water requirements:
Permanent 24h/24h
Start at any time of
the day.
Programming
Start
only
in scheduled
periods.
Duration of the 1st slot: from 4 to 14 hours;
Total duration of the 2 slots: minimum 8 hours
and maximum 14 hours.

Language.
Possible settings in French, English, Dutch,
Spanish, Portuguese, German, Italian and

3.5 PARAMETERS TO BE ADJUSTED
UPON INSTALLATION.
(If not set at the time of commissioning)
The parameters can be accessed in INSTALLER
MODE.
Hold down the Menu button (2 Fig. 3-1) and
turn the selector switch (1 Fig. 3-1) by a half
turn to the right.
To exit the installer mode, proceed in the same
way or wait for 10 minutes.

Air ducts (aeraulic operation).
This parameter defines the aeraulic connection
type realised:
Inner / Inner
Suction and return not
connected to air ducts
(ambient air)
Outer / Outer
I n t a k e a n d r e t u r n
connected to air ducts
(coated air)
Inner / Outer

In "Connected to boiler" it is asked to define a
preference relating to the operation of priorities
between the boiler and the heat pump according
to 4 levels:
Heat pump
prioritised
The integration will be
only active at the end of
the heating for very low air
temperatures (<7°C)
Heat pump
optimised
The integration will be only
active until the end of the
heating and ± early depend-
ing on the air temperature
Boiler
optimised
The heat pump is activated
at the end of the heating
and ± soon as a function
of air temperature
Boiler
prioritised
The heat pump is active at the
beginning of heating and for
air temperature >10°C.
•
PV system/Smart-grid.
This parameter is used to activate the device
coupled with a photovoltaic system. This oper-
ating mode generates theforced start of the heat
pump when the water heater receives a signal
coming from the photovoltaic system. The setting
automatically returns to the previously selected
mode after 5 minutes if the photovoltaic system
signal is lost. While receiving the signal the set
point temperature is automatically set at 62°C
(not adjustable).
•
Exhaust air.
It allows you to turn on the air extraction func-
tion (2 speeds: low or hight). When the unit
does not heat domestic water, the fan turns
on to evacuate the ambient air to the outside
(only activated when the aeraulic connection
type is Inner/Outer).
•
Anti-legionalla function.
It allows you to turn on the water disinfection
function adjustable from 1 to 4 times a month.
The water temperature reaches 62°C during
the cycle.
•
EMERGENCY mode.
Enabling this mode allows continuous oper-
ation only with the electrical integration. The
programming slots are not considered.
•
Additional electric backup.
It allows you to activate or not the electrical
integration support. If it is off, the device will
never use the electrical integration; in case
of low temperatures, a shortage of hot water
is possible.
3.6 SELECTING THE OPERATING
MODE.
Press

to access the
Mode
menu.
•
In AUTO mode (this mode is not available
on the “Connected to boiler” and “Connect-
ed to solar sys.” systems).
This operating mode automatically manages
the energy choice that allows maximum sav-
ings while guaranteeing an adequate comfort
in terms of hot water. The water heater anal-
yses the consumption of the previous days to
adapt the production of hot water according to
needs. It reacts to unexpected events to ensure
the hot water making relaunches during the
day. Therefore, the set point temperature is
automatically adjusted between 50 and 62°C
according to the consumption profile. The
Water heater operates preferably through the
heat pump. The electrical integration can be
automatically selected to ensure a sufficient
volume of hot water.
N.B.:
this mode is not available on the “Con-
nected to the boiler” and “Connected to solar
sys.” plants.
•
MANUAL mode.
This mode allows you to define the desired
amount of hot water by choosing the set
point. This set point is also represented as an
equivalence of number of showers (about 50
litres of hot water). The products complies
with the operating slots defined through the
user’s time programming.
If the ECO mode is not active, the water
heater favours operation with heat pump
only. However, if the air temperature is low
or consumption remarkable, the electrical
integration (or boiler) can be authorized as
a support at the end of heating to reach the
temperature set. If the ECO mode is active, the
water heater works only with the heat pump
with an air temperature ranging from -5 to
+43°C. Therefore electrical integration is not
authorised at the time of heating. This feature
optimises the savings, but can cause hot water
shortages. Regardless of the ECO adjustment,
if the air temperature exceeds the operating
time slots, the electrical integration will be
automatically selected to ensure a sufficient
volume of hot water.
PLEASE NOTE:
the ECO active/non active
modes are not available on “Connection to
the boiler” plants.
PLEASE NOTE:
MANUAL mode and “Con-
nected to solar sys.” plants: this mode also
allows the operation of the heat pump in ad-
dition to the solar system. The contemporary
prolonged operation of the heat pump and of
the solar system may damage the product. It
is therefore necessary to allow the operation
of the heat pump only in the absence of solar
energy (use the time programming of the
heat pump).
•
BOOST mode.
This mode activates the heat pump and all
other available sources of energy (if declared
boiler integration, electrical integration)
without considering the authorised periods of
operation. The number of the BOOST opera-
tion days is adjustable from 1 to 7. The setpoint
temperature (62°C) cannot be adjusted.
At the end of the chosen period, the water heater
resumes operation with the initial settings.
The BOOST can be interrupted at any time.
•
ABSENCE mode.
This mode maintains the domestic hot water
temperature above 15°C using the heat pump.
The boiler and electrical integrations can be
activated if the heat pump is not available.
The function can be interrupted at any time
•
CIRCULATION cycle.
This mode allows the heat pump to operate
continuously to reach the set point of 62°C.
The integrations (if declared boiler and elec-
tric) are activated after 7 hours of heating with
the heat pump.
