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).

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.

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.

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.
