Two operating modes are available:

1) Manual temperature adjustment (refer to the “Temperature adjustment and function activation” paragraph):

with the “ECO” button o, the “manual” mode activates. In this mode, the product continues to full the user’s energy

demand, though without modifying the temperature selected by the user. Once the “ECO” button is pressed, the

corresponding LED lights up and the “ECO EVO” function restarts, which in this case is eective since the outset as

the “learning” phase has already occurred;

2) ECO EVO:

- After one week of continuous learning, at every moment the water heater generates the hot water quantity

according to a statistical demand forecast which is updated over time: to do this, the temperature is automatically

determined and will be always comprised between a Tminimum=40°C and the maximum temperature set by the

user (by default, the maximum temperature is equal to the value appearing in the technical sheet [Annex A]).

- Prolonged pressing of the “ECO” button causes the corresponding LED to ash for roughly 4 seconds and the

learning process starts from the beginning (from the rst week). This action is used to delete the user’s needs

from the memory and restart (hard reset).

- Warning: when the “ECO” LED is lit, pressing the “+/–” buttons or the “ECO” button allows for accessing the

manual mode described above (the “ECO” LED switches o).

In order to ensure correct operation of the ECO EVO function, the product should not be disconnected from the

mains electricity.

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 °80C by bypassing the previous operating

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).

The Max function is deactivated even if there is a stall error, if the “OFF” status is engaged or if the +/– buttons are

pressed to change the set-point.

Setting the set-point

By pressing the PLUS or MINUS buttons, the user can choose the set-point temperature (indicated by the temperature

LEDs, with the other LEDs o). Each press of the button increases or decreases the set temperature by 10 degrees. After

5 seconds without any action, the set-point will be conrmed and memorised.

STALL STATUS

There are two possible stall statuses:

- TOUCH CONTROL STALL STATUS

If a touch control error is detected, the status of the touch LED is undetermined and cannot be controlled.

This status is indicated by the ashing of the temperature LEDs (fast if the product is on, slow if it is o).

- OTHER STALL STATUS

If other errors are detected, all the LEDs will start ashing.

To reset a non-volatile error, if possible, it is necessary to press the ON/OFF button (Fig. 3A) to switch the product

on and o. To verify which error occurred, it is necessary to enter the diagnostics state by simultaneously pressing

the ON_OFF and MAX BUTTONS for 3 seconds. In this state, the temperature LED must show the defect according

to Table 1.4. After 25 seconds, the system will return to the stall status. Note: for the Chinese market (set through

NFC), the product is reset by simultaneously pressing the ON/OFF and ECO buttons for 5 seconds.

The heater has a thermostat. If the thermostat is set at 80 Centigrade and there is a power cut does the temperature setting remain at 80 when power is restored ? Submitted on 29-1-2022 at 17:10
