4.4 Troubleshooting

Diagnostics
In case of operation faults or problems, the display flashes and the fault identification
code appears.
There are faults that cause permanent shutdown (marked with the letter "A"): to restore
operation just press the reset button (detail 6 -fig. 1) for 1 second or RESET on the op-
tional remote timer control if installed; if the boiler fails to start, it is necessary to firstly
eliminate the fault.
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.
