Boost Function; Anti-Freeze Function - Ariston VELIS DRY Instructions For Installation, Use, Maintenance

BOOST FUNCTION

The BOOST function temporarily sets the set-point temperature to 80°C, by-passing the previous oper-
ating mode (if the ECO function is active, the auto-learning function will be temperarily suspended anwill
resume automatically once the set-point is reached).
To activate or deactivate the BOOST function, press the correspondign buttos. If the function is activ, the
correspondign LED will be lit. If the product is switched OFF using the ON/OFF button " ", if the " " "
" buttons are pressed to change the set-point or if a shut-off error appears, the BOOST function will
be deactivated.
PROTECH FUNCTION
The "PROTECH" function activates for the product, an electronic system that protects against corrosion orig-
inateci by the water-metal contact, ensuring excellent longevity of the appliance's tank in case of chemically
aggressive water. The principle of operation is the following: the electronic circuit creates a difference in
potential between the tank and the titanium electrode, thereby guaranteeing excellent protection of the tank,
preventing corrosion due to the galvanic effect. For correct system operation, it is necessary to guarantee the
permanent connection of the product to the electric al power mains.
In the presence of a malfunction of the function, the display will show the error code E04.
Also in the case of appliance downtime, turn the product off by the ON/OFF " button, disconnect it from
the electrical power mains. lf you wish to switch the electrical power supply off tor long periods of time, it is
advisable to empty out all of the water contained in the appliance (see "Maintenan ce" paragraph) to ensure
increased durability of the tank/resistance.

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).
WEEKLY PROGRAM FUNCTION
The weekly program function can only be activated through the App.
Two different setpoint temperatures at two different times can be selected for each day of the week: the
product will calculate the heating speed and, depending on the temperature, the best moment to start
heating in order to reach the setpoint at the desired time.
Press the " " or " " buttons to deactivate the function.
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 " " buttons for 3 seconds;
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.
