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.
