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" mode is selected, the S.A.R.A. Booster function is
activated for the heating circuit. This function allows to reach the
required ambient temperature more quickly.
Depending on the temperature set on the ambient thermostat and
the time taken to reach it, the boiler automatically adjusts the heating
water temperature to reduce operating times, thereby increasing
operating comfort and energy saving.
