START-UP
WARNING!
The installation and initial start-up of the appliance must be per-
formed by qualified personnel in compliance with the national reg-
ulations in force regarding installation.
CONTROL PANEL
The user interface has LCD display and 7 touch buttons. There are
2 blue leds: ON (when the product is power supplied) and BOOST
(when BOOST has been activated).
MODE
List of the icons shown on the display:
Changeable parameter
Wi-Fi enabled (only if present)
Schedule programming enabled
Day of the week (1 = Sunday)
Heat pump active
Heating element integration enabled
ANTIBACTERIAL function is enabled
PV or SG enabled (only if present)
When the corresponding mode is active, the secondary
string indicates it
SILENT function is enabled
ANTIFREEZE function is enabled
Top temperature sensor > T SETPOINT + 6°C
Hot water shower available
Estimated Energy Content
(based on the set temperature)
Once the appliance is connected to the hydraulic and electric sys-
tems, the water heater must be filled with water from the domestic
water supply network. In order to fill the water heater, it is neces-
sary to open the central tap of the domestic network supply and the
nearest hot water tap, while making sure that all the air in the tank
is gradually expelled. Visually inspect for possible water leaks from
the flange and pipe fittings and gently tighten them, if necessary.
The heat pump requires 5 minutes to become fully operational when
starting it for the first time.
WARNING! Hot water at temperatures above 50 °C running from
taps may immediately cause serious burns. Children, the disabled
and the elderly run a greater risk in this regard. Therefore, it is
advisable to use a thermostatic mixing valve connected to the ap-
pliance's water outlet pipe, which is identified by a red collar.
WARNING!
If the water temperature is higher than the set temperature by 6°C,
the display shows the icon

INSTRUCTIONS FOR USE
Press the "
" button to turn the water heater on.
The display shows the set temperature and operation mode, while
the "
" symbol and/or "
of the heat pump and/or heating element respectivel.
Press the "
" button for 1 second to switch off the water heater.
The protection against corrosion is ensured. The product ensures
that water temperature inside the tank does not fall below 5°C.
SETTING THE TEMPERATURE
+
-
Press the "
" and "
" to set the desired hot water temperature (T
SET POINT, the display will temporarily flash).
Press " SET " button to display the temperature of the water in the
tank; it will be shown for 3 seconds.
In heat pump mode the min/max temperatures achievable are
40°C/55°C, by default settings. This range can be extended (min/max
40°C/62°C) in the installer menu. The maximum achievable tempera-
ture with the heating element is 75 °C. Changing the settings on the
installer menu this valure can vary.
SHOWERS AVAILABLE "
When the display shows the icon, it means that at least one shower
is available. The available showers depend on the availability of hot
water. One shower is calculated as: 40 l at 40°C.
MODE OF OPERATION
With the " MODE " button you can modify the operating mode used
by the water heater to reach the set temperature. The selected mode
will be displayed on the line below the temperature.
If the heat pump is active, this symbol appears "
If the electric heating element or integration is enabled, this symbol
will appear "

• GREEN
only the heat pump works, the priority is given to energy saving.
The maximum achievable temperature depends on the value of
the P7 parameter (40°C-62 °C) – (refer to Paragraph 7.7). Only for
back-up or safety mode (errors, air temperature out of operating
range, defrosting process in progress, antilegionnaire's disease),
the heating element may turn on and work.
• COMFORT
the water heater reaches set temperature with the rational use of
the heat pump and, only if necessary, of the heating element. The
priority is given to comfort.
• FAST
permanent boost mode, the water heater uses both heat pump
and heating element to reach set temperature. The priority is giv-
en to heating time.
• I-MEMORY
mode designed to optimize energy consumption and maximize
comfort by monitoring the hot water needs of the user and the
optimized use of the heat pump/heating element. The algorithm
guarantees each daily need proposing the average of the profiles
detected over the previous 4 weeks. In the first week of acquisi-
tion, the set point temperature entered by the user remain con-
stant; from the second week onwards, the algorithm will automat-
ically adjust the set point temperature to ensure daily needs. To
reset the I-Memory profile use U9. (IMemory mode is visible when
U1: PROGRAM is "OFF")
• HC-HP
mode heating is performed within HC-HP signal detection in order
to heat when low-tariff energy is available. The target temperature
depend on the particular HC-HP mode selected:
- HC-HP: when signal EDF is detected, HP and HE can work (pri-
ority is given to HP). Antifreeze protection is guaranteed all day
long.
- HC-HP_40: when signal EDF is detected it works as HC-HP, oth-
erwise temperature is maintened at 40°C (HP only)
- HC-HP24h: when signal EDF is detected it works as HC-HP, oth-
erwise set temperature is achieved with
