3.4 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 8 - fig. 1) for 1 second or RESET on the optional remote timer control if installed; if the boiler fails to start,
it is necessary to first eliminate the fault.
Other 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.
