SHOWER READY FUNCTION
For model equipped with user interface type shown in fi gure 9
The product is equipped with an intelligent function to minimise water heating time. Regardless of the
tem perature set by the user, the symbol "
" 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).
ANTI-FREEZE FUNCTION
The anti-freeze function is the appliances automatic protection to avoid damages caused by very low
tempe ratures below 5 °C, in the event in which the product is turned off during winter. It is recommended
that the product remains plugged in to the mains power, even if is inactive for a long time.
THERMAL DISINFECTION FUNCTION (Anti-Legionella)
The Anti-Legionella function is activated by default. It consists of a water heating/60°C temperature
mainte nance cycle for 1 hour which has a thermal disinfection action on the relative bacteria.
The cycle starts when the product is started up and when it is restarted after a power outage. If the
product always functions at temperatures lower than 55°C, the cycle is repeated after 30 days. When the
product is switched off , the anti-Legionella function is deactivated. If the equipment is switched off during
the anti Legionella cycle, the product switches off and the function is deactivated. At the end of the cycle,
the use temperature returns to the temperature previously set by the user.
The activation of the anti-legionella cycle appears as a normal temperature adjustment 60°C. Activate
this function by pressing and holding both the "ECO" and "+" buttons for 4 s.; once activation is con-
fi rmed, the LED (Ref. 4) will fl ash quickly for 4 s.
Permanently deactivate the function by repeating the above steps; once the deactivation is confi rmed,
LED 40°c (Ref. 1) will fl ash quickly for 4 s.
RESET/DIAGNOSTICS
For models equipped with user interface type shown in fi gure 9
When one of the malfunctions described above occurs, the appliance will enter its "fault status" and all
LEDs on the control panel will fl ash simultaneously.
Diagnostics: to enable the diagnostic function, press contemporary ON-OFF button (ref. A) and MINUS
button for 3 sec. The type of fault is indicated by fi ve 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
LED Ref. 2, 3, 4 and 5 - overheating caused by lack of water - boiler inlet
Exit the diagnostic function by pressing the ON/OFF button (Ref. A) or wait for 25 seconds.
