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 20 - fig. 1) indicating the fault
code.
There are faults that cause permanent shutdowns (marked with the letter "A"): to restore
operation it is sufficient to press the RESET button (part 8 - fig. 1) for 1 second or use
the RESET on the remote timer control (optional) if installed;if the boiler does not restart
it is necessary to resolve the fault first.
Other faults cause temporary shutdowns (marked with the letter "F") that are automati-
cally reset as soon as the value in question returns to within the boiler's normal working
range.
