Eco Function - Ariston VELIS DRY Instructions For Installation, Use, Maintenance

Advice for user
- Avoid positioning any objects and/or appliances that could be damaged by water leaks beneath the
water heater.
- Should you not use any water for an extended period of time, you should:
• disconnect the appliance from the electrical supply by switching the external switch to ''OFF";
• turn off the plumbing circuit taps;
- Hot water at above 50°C flowing out of the taps at the point of use could cause serious scalds or even
death from burns. Children, the disabled and the elderly are more exposed to the risk of burns. It is
strictly forbidden for the user to perform any routine or extraordinary maintenance.
To clean the external parts use a damp cloth soaked in soap and water.
OPERATION AND ADJUSTMENT OF THE OPERATING TEMPERATURE
The product is set to a temperature of 70°C for the 30, 50 and 80 l models and to 60°C for the 100 l
model. The "ECO" function is active. In case of power shortages, or if the product is switched off using
the ON/OFF button " ", the product memorises the last set temperature.
During the heating phase, slight noise may occur due to the heating of the water. Press the ON/OFF
button " " to switch the appliance on.
Use the " " " " buttons to set the desired temperature to a value between 40°C and 80°C as shown
on the display. During normal operation, the display will show the temperature reached by the water
inside the product. During the heating phase, the status indicator (Fig. 8, Ref. 1) is red and turns blue
once the set temperature is reached. If the water temperature drops, for example after a withdrawal, the
heating function will be automatically activated.
HOT WATER LEVEL
The indicators on the sides of the display (Fig. 8 Ref. 2) allow to check the level of hot water inside the
water heater, on a four-segment scale. While the temperature is being set, the indicators light up to en-
able the user to visually check the set level.
During the heating phase the indicators light up gradually, indicating the increase in the temperature of
the hot water inside the product, until the set temperature is reached.

ECO FUNCTION

The "ECO" function is a software programme that automatically "learns" the user's consumption levels,
reducing heat dispersion to a minimum while maximising energy saving. The "ECO" software programme
requires an initial memorisation period that lasts one week, during which the product starts operating
at the set temperature. At the end of this "learning" week, the software programme adjusts the water
heating according to the user's actual needs, which are automatically identified by the appliance. The
product guarantees a minimum hot water reserve also when there are no water withdrawals.
The learning process regarding the hot water requirements continues even after the first week.
The process reaches its full efficiency after four weeks of learning.
In order to ensure the programme's correct operation, the product should not be disconnected from the
mains electricity.
An internal memory ensures that the data will be stored for a maximum of 4 hours without electricity.
After this time, all the acquired data will be deleted and the learning process will start from the beginning.
To activate the function, press the "ECO" button, which will light up.
In this mode, the temperature can still be selected manually, but adjusting its value will deactivate the
ECO function. This function can be deactivated by pressing the "ECO" button, which will turn off.
To reactivate it, press the "ECO" button again.
To voluntarily delete the acquired data, press and hold the "ECO" button for more than 3 seconds. Once
the reset process has been completed, the "ECO" button will flash quickly to confirm the deletion of the
data.
