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 start, it is necessary to firstly
eliminate the fault.
Other faults (marked with the letter "
F ") cause temporary shutdowns that are automati-
cally reset as soon as the value returns within the boiler's normal working range.
