Power Function; Anti-Freeze Function - Ariston VELIS TECH INOX PW ABSE 30 Assembly And Operation Instructions Manual

POWER FUNCTION

The "POWER" function allows the device to function at the maximum power, thus reducing the time
required to heat the water.
To activate or deactivate the POWER function, press the corresponding button.
If the function is active, the corresponding LED will be lit.

ANTI-FREEZE FUNCTION

The anti-freeze function automatically protects the appliance, preventing damages caused by very low
temperatures, below 5°C, if the product is switched off during the winter season. We recommend leaving
the product connected to the mains electricity, even in case of prolonged inactivity. Once the temper-
ature rises to a safer level that prevents damages caused by ice or frost, the water heating function
switches off again.
The function is enabled, but in case of activation it does not indicate whether the product is ON. When
the product is switched off using the ON/OFF button " ", if the anti-freeze function is active the display
will show "AF" (Anti-Freezing).
THERMAL DISINFECTION FUNCTION (Anti-Legionella)
The Anti-Legionella function is activated by default. It consists of a water heating/60°C temperature
maintenance 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 prod-
uct 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.
To activate this function, simultaneously press and hold the "ON/OFF" and "
the display will show "A1" for 4 seconds to confirm the activation. To deactivate the function permanently,
repeat the operations described above; the display will show "A0" for 3 seconds to confirm the deacti-
vation.
