4.4 Troubleshooting

Diagnostics
The boiler is equipped with an advanced self-diagnosis system. In case of a boiler fault,
the display will flash together with the fault symbol (detail 22 - fig. 1) indicating the fault
code.
There are faults that cause permanent shutdown (marked with the letter "A"): to restore
operation just press the RESET button (detail 8 - fig. 1) for 1 second or RESET on the
optional remote timer control if installed; if the boiler fails to restart, it is necessary to elim-
inate the fault indicated by the operation LEDs.
Faults marked with the letter "F" cause temporary shutdowns that are automatically reset
as soon as the value returns within the boiler's normal working range.
