point of 30°C will be automatically set if you use the check on the delivery water,
or 10°C if you use the ambient air check (installing the specic air probe accessory).

— You can set up to three time bands (periods) for each day; their start and end
times must be coherent (the start of one period must be later than the end of
the previous one);
— When the weekly timer has been activated, the display panel will act based on
the current mode and temperature setting;
— The “With” setting for one or more days of the week validates the specied time
settings only if the Weekly Timer is “On”;
— “Without” = the Weekly Timer is also active, this day will not be considered;
— When both “Weekly timer” and “Holiday release” have been activated, setting of
“Weekly timer” is invalid.
— The priority sequence for timer setting from high to low is “Temperature tim-
er”, “Clock timer”, “Preset mode” and “Weekly timer”. Setting with lower priority
sequence is allowed but does not work when setting with higher priority has
been activated. However, it will work when the setting with higher priority has
been deactivated.
— If the relative function is activated (paragraph "8.1Activating/deactivating the
memory (On/o memory)p.32"), the value of this parameter will be stored in

munication error or an error linked to the storage tank accessory;
— If the relative function is activated (paragraph "8.1Activating/deactivating the

the memory and automatically reset after any possible voltage failure.
WARNING: if the unit is used to produce domestic hot water, the Anti-Le-
gionella Cycle MUST be set. The ANTI-LEGIONELLA CYCLE is related to only
the mandatory tank accessory. To ensure a reduction in and control of the
legionella risk, the preventive measures indicated in the guidelines, regula-
tions and local rules must be adopted.
