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.

Troubleshooting

When a fault appears on the display, the flame symbol goes out,

a flashing code is shown and the two symbols and

appear either together or separately.

For a description of the faults, consult the following table.

(D) Permanent

(T) Temporary. In this operating status the boiler attempts to eliminate the fault on its own

(°) Only with external water tank with sensor. The fault code is shown when the boiler is in stand-by

(*) For the “insufficient circuit pressure” fault, proceed with the circuit filling operations described in the “Boiler functions” chapter.
