Important note:

Important note: Dielectric junctions must be fitted to all models as they prevent an electrolytic reaction and safeguard against potential aggressive corrosion. User instructions Recommendations - Do not place anything under the water heater which may be damaged by a leak. - If the water is not used for a long time: ➣ shut off power to the appliance by setting the external switch to "OFF"; ➣ close the water circuit cocks. - Water heated to over 50C can cause immediate serious burns or even death. Children, disabled persons and the aged are particularly at risk of burns. Do not attempt to service or repair the appliance. Reset/Diagnostics When any of the faults described below occurs, the device goes into fault status and all the LEDs on the control panel flash simultaneously. Reset: reset the appliance by switching it off and on from the key (A fig.6). If the cause of the fault disappears when reset, the appliance resumes its regular operation. Otherwise, all the LEDs start to flash again and Technical Assistance must be requested to intervene. Diagnostics: activate the diagnostics by pressing the key (A fig.6) for 5 seconds. The indication of the type of fault is provided via 5 led (1➔5 fig.6) according to the following diagram: LED ref. 1 – Fault inside the board; LED ref. 2 - Fault at the anode (in models with an active anode); LED ref. 3 - Faulty NTC 1/NTC 2 temperature sensors (open or short circuited); LED ref. 5 - Water over temperature detected by a single sensor; LED ref. 4 and 5 - General over temperature (board failure); LED ref. 3 and 5 - Probe differential error; Exit the diagnostics by pressing the key (A fig.6) or wait 25 s. Activating the "thermal disinfection cycle" (anti-legionella) The product has the "thermal disinfection cycle" disabled by default. The activation of the "thermal disinfection cycle" is displayed as a normal temperature setting at 60°C. Activate this function by pressing and holding both the "ECO" and "+" keys for 4 s.; once activation is confirmed, LED 60 will flash quickly for 4 s. Permanently deactivate the function by repeating the above steps; once the deactivation is confirmed, LED 40 will flash quickly for 4 s. Adjusting the temperature and activating the functions of the device Switch the device on by pressing the key (A fig.6). Set the desired temperature by selecting a level between 40°C and 80°C using the ”+” and “-“ buttons. During the heating phase, the LEDs (1➔5 fig.6) related to the temperature reached by the water remain on; the subsequent ones until the temperature is set, flash progressively. If the temperature drops, for example due to water being drawn, the heating is automatically reactivated and the LEDs between the last one on (steady) and that related to the set 10

temperature start to flash progressively again. When first switched on, the product is set to 70°C. In case of a power failure or if the product is switched off using the button (A fig.6), the last temperature set remains saved. Slight noise may occur during the heating phase due to the water being heated. ECO EVO function The "ECO EVO" function consists of self-learning software of the user consumption, which allows heat loss to be minimised and energy savings to be maximised. This function is active by default. The "ECO EVO" software consists of an initial learning period of a week when the product begins to operate at the temperature indicated in the product data sheet (Attachment A) and logs the user energy demand. From the second week onwards the learning process continues so as to learn the user requirements in more detail and changes the temperature every hour to adapt it to the actual demand in order to improve energy savings. The "ECO EVO" software activates the heating of the water within the time and amounts determined automatically by the product itself according to user consumption. During the day, when no water is drawn, the product still guarantees a reserve of hot water. Activate the "ECO" function by pressing the relevant key that lights up green. Two operating modes are possible: 1) Manual adjustment of the temperature (see the "Adjusting the temperature and activating the functions of the device" paragraph): the manual mode is accessed with the ECO button off. In this mode, the product continues to note the user's energy demand without adjusting the temperature selected by the user. Press the "ECO" key for it to light up and the "ECO EVO" function to start, which is immediately effective in this case as the "learning process" has already been implemented; 2) ECO EVO: - After the first week of continuous learning, the water heater always prepares the amount of hot water according to a statistical prediction of demand which is supplied in time: to do so, the temperature will be automatically determined which will always be between a Tminimum=40°C and a maximum temperature that is set by the user (by default, the maximum temperature is equal to the value shown in the data sheet [Attachment A]) - Press the ECO key for long for the eco LED to flash for about 4 s and the learning process restarts (from the first week). This is used to delete the user demand from the memory and restart (hard reset). - Caution: when the ECO key is on and the "+/-" keys (Fig.6) or the knob (Fig.6) or the "ECO" key itself are pressed, the Eco soft mode described above is accessed (the ECO key goes off). In order to guarantee proper ECO operation, it is recommended not to disconnect the product from the mains. Anti-limescale Function: If much limescale is detected, the product switches to limited mode, which is actually "manual" mode with the heating temperature set to 65°C and the ECO SMART function disabled. Warning: the first 3 heating LEDs flash simultaneously (Fig.6➔1;2;3) 11
