USER INSTRUCTIONS

Reset/Diagnostics

When one of the malfunctions described above occurs, the appliance will enter its "fault status" and all LEDs on the

control panel will flash simultaneously.

Reset: to reset the appliance, switch the product off 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 flash; 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 five LEDs (Ref. 1 >5) according to the following scheme:

LED Ref. 1 – Internal P.C.B. malfunction;

LED Ref. 2 – Anode malfunction (in models fitted 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, 4 and 5 – Operation without water.

Exit the diagnostic function by pressing the

button (Ref. A) or wait for 25 seconds.

"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 first 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 off, the anti-

legionella function is not active. If the appliance is switched off during the anti-legionella cycle, the product turns off

and the function is not completed. At the end of each cycle, the operating temperature returns to the value set previ-

ously by the user. The activation of the "anti-legionella cycle" is displayed as a normal temperature setting at 60°C. (Led

Ref. 4). To permanently disable the anti-legionella function simultaneously hold down the "ECO" and "+" buttons for 3

sec.; confirming deactivation the led 40° will C flash rapidly for 4 sec. To reactivate the anti-legionella function, repeat

the operation described above; to confirm the reactivation of the led (Ref. 4) will flash rapidly for 4 sec.

Adjusting the temperature and activating the functions (Fig. 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 65°C. During the heating phase, the LEDs (Ref. 1> 5) corresponding to the temperature

reached by the water so far remain lit in a fixed manner; all subsequent LEDs (up to the set temperature) flash 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 fixed light and the light corresponding to the set temperature will resume flashing progres-

sively. The first time the product is switched on, it will be set to a temperature of 60°C (Led Ref. 4).

In the event of a power failure or if the product is switched off using the button (Ref. A), the most recently set tempera-

ture 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 FUNCTION

The Eco function is activated/deactivated by pressing the corresponding button. If the function is activated the led will

be switched on. The Eco function aims to produce hot water by learning the user habits. So, for the first week ever the

product memorises the tappings and the periods in which those tappings take place. From the following weeks the wa-

ter heating is performed regarding what was learned previously. If the user wants to reset the function and start a new

learning period, it is necessary to press the ECO button for 3 seconds (the eco led will appear blinking).

If during Eco function, PLUS or MINUS button are pressed the function will be deactivated.

SHOWER READY

The Shower Ready LED (B, Fig. 3) indicates whether there is hot water for at least one shower. The quantity of hot water

is determined by internal parameters and varies according to the model.

MAX FUNCTION

The Max function (C, Fig. 3) is activated/deactivated by pressing the corresponding button. If the function is active, the

LED will be lit. The Max function temporarily sets the set-point temperature to 65°C by bypassing the previous operat-

ing mode (if the Eco function is active, the self-learning function is temporarily interrupted and deactivates on its own

once the set-point is reached).
