S.A.R.A. function
If the "winter" mode is selected, the S.A.R.A. (Automatic Ambient
Adjustment System) function can be activated.
Turn the heating water temperature selector to a temperature ran-
ging between 55 and 65 °C.
The S.A.R.A. self-adjustment system activates: depending on the
temperature set on the ambient thermostat and the time taken to
reach it, the boiler automatically adjusts the heating water tem-
perature to reduce operating times, thereby increasing operating
comfort and energy saving.

Troubleshooting

When a fault appears on the display, the fl ame symbol
out, a fl ashing code is shown and the two symbols
appear either together or separately.
For a description of the faults, consult the following table.

(*) For the "insuffi cient circuit pressure" fault, proceed with the circuit fi lling operations described in the "Boiler functions" chapter.
S.A.R.A. BOOSTER function
If the "winter comfort" mode is selected, the S.A.R.A. Booster fun-
ction is activated for the heating circuit and reaches the required
ambient temperature more quickly.
DOMESTIC HOT WATER PRE-HEATING function
If the "winter comfort" mode is selected, the domestic hot water
Preheating function is enabled. This function sets out to keep the
domestic hot water contained in the boiler hot, thereby considerably
reducing delivery waiting times.
The function should be selected to reduce power consumption
in areas where the mains water is not particularly cold.
In this case, the Booster and Preheating functions are not activated.
