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 11 - fig. 1) indicating the fault
code.
There are faults that cause permanent shutdown (marked with the letter "
A "): to restore
operation, 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 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.
