Product Highlights
Eco Evo
Function: This is an intelligent mode in which the product
will learn
the
user’s energy demand and continue to deliver hot water when needed as
determined by
the product in the learning period. (See Eco Evo section for more)
Anti-legionella: Legionella is a small rod-shaped
bacteria which can be found
in
all fresh water and it grows best between 20° and 45°C. Legionaries’
disease
is a pneumonia infection caused by inhaling
the Legionella bacteria.
This product has a “thermal disinfection cycle” in place to
restrict the
growth of this
bacteria by raising the temperature of the water above 60° for 60
minutes
once a month.
This is activated by default (factory setting), but the cycle
will start automatically only if the default temperature (65°C) is changed below 60°C.
The activation / deactivation of the “thermal disinfection cycle” can be
done through the User Menu (
Refer user menu section for more).
Leakage Detection:
This product is equipped with a
leakage sensor which will
detect
if there is a water leak and will notify the user with an audio
alarm from the
HMI module.

savings
.
When
"ECO EVO Function" is activated, the product starts
an initial learning
period of a week whe
re the product operates at the temperature set by the user
and logs the user
s energy demand. After the initial learning period, "ECO EVO
Function
" will provide hot water when needed according to user consumption.
During the day, when no water is drawn, the product still guarantees a reserve of
hot water.
To reset the “ECO EVO Function” and restart the learning period press
the “ECO
EVO” button for 3 second, the relevant LED will blink for 5 seconds then the
learning period will start again.
In order to guarantee proper “ECO EVO”
operation, it is recommended not to disconnect the product from the main power
supply
. In the ca
se of a power outage, depending on its duration, the HMI may
retain the Eco Evo memory.

Leakage detection
The product is supplied with a Leakage Sensor cable, which should
be placed in
the drip tray as shown in the picture Fig.11. This is to ensure that the sensor
will
most likely be able to detect a water leak.
The function of the Leakage Sensor is
to detect water presence in the drip tray and prevent damage caused by flood
ing.
In the unlikely event that this occurs:
•The sign “driP” will appear on the HMI (Fig.12);
•“HEATING” LED blinks;
•The HMI buzzer starts sounding;
Fig. 12
Fig. 11
To stop the sound and switch off the geyser press the power
button. If the
HMI is on, the buzzer will start to sound again.
Caution: During the leakage intervention, power supply to the water heater
will
not be interrupted. To switch off the power supply, press the Power
button
on the HMI module.
To reset the water heater, call the Ariston Call Centre on 010 745 9911
. When this
fault occurs, only a specialized technician can reactivate the water heater.

Power outage considerations
In case of
a power outage the user settings will not be lost
(operating mode,
temp
erature setting, scheduling setting and Anti-Legionella on/off).
Functions related to the c
lock will be stored on the HMI for at least 2 hours (ECO-
EVO
memory, timer programming and Anti-Legionella 30day cycle timing).
In cases where power outages last longer
than 2 hours, the following may occur:
•User will need to manually set the time;
•If the user adjusted temperature is below 60°C, the Anti-
Legionella
cleansing cycle will automatically start;
•Eco Evo mode (if active) will restart the learning period;
