3.4 ECO PLUS
Only for VLS PREMIUM version.
If one of the programming modes ("P1" or "P2" or "P1 and P2") is used in conjunction with the "ECO"
function, the temperature is set automatically by the appliance and the desired time band for hot water
availability is set manually by the end user. This operating mode maximises the amount of energy saved.
If the "SET" knob is moved, "PLUS" appears on the display for 3 seconds, indicating the simultaneous
operation of these two functions.
3.5 Anti-bacteria
The anti-bacteria function consists in a water heating cycle at 70 °C which carries out a thermal disinfection
action against the relevant bacteria.
The first cycle begins 3 days after the function activation. Subsequent cycles are performed every 30 days
(if, during that period, the water is not heated to 70 °C at least once). At the end of every cycle, the
operating temperature reverts to the value set previously by the user.
When the product is switched off, the anti-bacteria function is disabled but the days counter is able to run.
If the appliance is switched off during the anti-bacteria cycle, the product shuts down and the function is
disabled. When the product is switched on again, the function is active and able to resume its parameters.
After a disconnection by the power mains, when the appliance is connected again, the function is active
and able to work as a first activation has been done by the user.
