USER INSTRUCTIONS
Reset/Diagnostics
• For models featuring a user interface as represented in  gures 3.
When one of the malfunctions described above occurs, the appliance will enter its “fault status” and all LEDs on the
control panel will  ash simultaneously.
Reset: to reset the appliance, switch the product o and on again using the button (Ref. A). If the cause of the mal-
function disappears immediately following the reset process, the appliance will resume normal operation. If this is not
the case, all the LEDs will continue to  ash; contact the Technical Assistance Centre.
Diagnostics: to enable the diagnostic function, hold the
button (Ref. A) for 5 seconds. The type of fault is indicated
by  ve LEDs (Ref. 1 5) according to the following scheme:
LED Ref. 1 – Internal P.C.B. malfunction;
LED Ref. 2 – Anode malfunction (in models  tted with active anode);
LED Ref. 3 – NTC 1/NTC 2 temperature sensors broken (open or short-circuited);
LED Ref. 5 – Water overheating detected by an individual sensor;
LEDs Ref. 4 and 5 – General overheating (P.C.B. malfunction);
LEDs Ref. 3 and 5 – Sensor di erential error;
LEDs Ref. 3, 4 and 5 – Operation without water.
Exit the diagnostic function by pressing the button (Ref. A) or wait for 25 seconds.
Reset: to reset the appliance, switch the product o and on again using the button (Ref. A). If the cause of the mal-
function disappears immediately following the reset process, the appliance will resume normal operation. If this is not
the case, the error code will continue to appear on the display; contact the Technical Assistance Centre.
"Thermal disinfection cycle" function (anti-legionella)
The anti-legionella function is activated by default. It consists of a heating/maintenance cycle of the water at 60°C for 1h
so as to carry out thermal disinfection action against the relevant bacteria.
The cycle starts at the  rst ignition of the product and after each re-ignition which follows a lack of mains power. If the
product always work at a temperature below 55°C, the cycle is repeated after 30 days. When the product is o , the anti-
legionella function is not active. If the appliance is switched o during the anti-legionella cycle, the product turns o and
the function is not completed. At the end of each cycle, the operating temperature returns to the value set previously by
the user. The activation of the "anti-legionella cycle" is displayed as a normal temperature setting at 60°C. To permanently
disable the anti-legionella function simultaneously hold down the "ECO" and "+" buttons for 4 sec.; con rming deactiva-
tion the led 40° will C  ash rapidly for 4 sec. To reactivate the anti-legionella function, repeat the operation described
above; to con rm the reactivation of the led 60° C will  ash rapidly for 4 sec.
Adjusting the temperature and activating the functions
• For models featuring a user interface as represented in  gures 3:
Press the button (Ref. A) to switch on the appliance. Set the desired temperature by using the “+” and “-” buttons to
select a level between 40°C and 80°C. During the heating phase, the LEDs (Ref. 1 5) corresponding to the temperature
reached by the water so far remain lit in a  xed manner; all subsequent LEDs (up to the set temperature)  ash progres-
sively. If the temperature drops, for example after hot water has been used, the heating is reactivated automatically and
the LEDs between the last  xed light and the light corresponding to the set temperature will resume  ashing progres-
sively. The  rst time the product is switched on, it will be set to a temperature of 70°C.
In the event of a power failure or if the product is switched o using the button (Ref. A), the most recently set tem-
perature remains memorised. During the heating phase, a slight noise may be produced as a result of the water heating
process.
The LED remains ON during heating.
ECO EVO FUNCTION
The “ECO EVO” function consists in a self-learning software applied to user consumption that allows for minimising
heat dispersal and maximising energy saving. This function, featured on products equipped with the “SMART” function
indicated in Table 1, is active by default.
The “ECO EVO” software runs an initial one-week learning period, during which the product starts functioning at the
temperature specied in the product sheet (Annex A) and records the user’s energy requirements. From the second
week onwards, the learning phase continues in order to understand the user’s needs more thoroughly and the
product adapts the temperature every hour to the energy requirements, for improved energy saving. The “ECO EVO”
software activates water heating in the time and in the quantity determined automatically by the product itself, based
on the user’s consumption. During periods of the day in which no withdrawals are planned, the product nonetheless
guarantees a reserve supply of hot water.
To activate the “ECO” function, press the relative button.
