Press the "set" button to start appliance operation in "P1" or "P2" mode. If "P1 and P2" have been selected
repeat the time and temperature setting for the second program. During the periods for which the use of hot
water is not explicitly required, water heating is disabled. The individual programs "P1" or "P2" are equivalent
and can be configured independently for greater flexibility. When one of the programming functions ("P1"
or "P2" or "P1 and P2") is enabled, the knob is disabled. If you want to change the parameters, you must
press the "set" button.
If one of the programming functions ("P1" or "P2" or "P1 and P2") is used in combination with the "ECO"
function (see paragraph "ECO EVO function"), the temperature is set automatically by the appliance and
only the desired time bands for hot water availability can be set
NB: for any setting, if the user takes no action for 5 seconds, the system saves the last setting.
ECO EVO Function
The "ECO EVO" function is a software program that automatically "learns" user consumption levels, redu-
cing heat loss to a minimum and maximising energy savings. The "ECO EVO'' software consists of an initial
saving period of a week, when the product begins to operate at the temperature set. At the end of this "le-
arning" week, the software adjusts water heating according to the user's real needs which are automatically
identified by the appliance. The product guarantees a minimum reserve of hot water even during periods in
which water is not withdrawn.
The hot water demand learning process, continues even after the first week. The process achieves maxi-
mum efficiency after four weeks of learning.
Activate the function by pressing the corresponding button, which will light up. In this mode, the manual
selection of the temperature is possible, however changing it disables the "ECO EVO" function.
Reactivate it by pressing the "ECO" button.
Whenever the "ECO EVO" function or the product is turned off and on again, the function will continue to le-
arn the levels of consumption. In order to guarantee proper operation of the program, it is recommended not
to disconnect the appliance from the mains. An internal memory ensures data storage for up to four hours wi-
thout electricity, after which all acquired data is cancelled and the learning process will begin from the start.
Each time the knob is rotated to set the temperature, the "ECO EVO" function is automatically disabled and
the relative writing turns off. The product continues to operate with the program selected, the ECO function
is not active.
To voluntarily cancel the acquired data, hold down the "ECO" button for more than 5 seconds. When the reset
process is completed, "ECO" flashes quickly to confirm data cancellation
"Shower Ready" Display
• For models equipped with user interface type shown in figure 8.
The product is equipped with an intelligent function to minimise water heating time. Regardless of the tem-
perature set by the user, the icon "shower ready" will turn on as soon as there is enough hot water for at
least one shower (40 litres of mixed hot water at 40 °C).
• For models equipped with user interface type shown in figure 9.
The product is equipped with an intelligent function to minimise water heating time. Regardless of the tem-
perature set by the user, the icon "shower ready" will turn on as soon as there is enough hot water for at
least one shower (40 litres of mixed hot water at 40 °C). Upon reaching sufficient hot water for a second
shower a second "shower ready" icon will light up and so on (the maximum number of showers depends
on the ability of the model purchased).
Reset/Diagnostics
• For models equipped with user interface type shown in figure 8.
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.
Diagnostics: to enable the diagnostic function, hold the ON/OFF 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 malfunction of the circuit board
LED Ref. 1 and 3 - internal malfunction of the circuit board (NFC communication or NFC data)
LED Ref. 3 - broken temperature probes (open or short circuited) - boiler outlet
LED Ref. 5 - excessive water temperature detected by single sensor - boiler outlet
LED Ref. 4 and 5 - general excessive water temperature (circuit board fault) - boiler outlet
LED Ref. 3 and 4 - Failure to heat water with powered heating element - boiler outlet
LED Ref. 3, 4 and 5 - overheating caused by lack of water - boiler outlet
LED Ref. 2 and 3 - broken temperature probes (open or short circuited) - boiler inlet
LED Ref. 2 and 5 - excessive water temperature detected by single sensor - boiler inlet
LED Ref. 2, 4 and 5 - general excessive water temperature (circuit board fault) - boiler inlet
LED Ref. 2, 3 and 4 - failure to heat water with powered heating element - boiler inlet
