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 shutdowns (marked with the letter "A"): to restore
operation, press the RESET button (detail 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 eliminate the fault indicated in the operation LEDs.
Other faults cause temporary shutdowns (marked with the letter "F") which are automat-
ically reset as soon as the value returns within the boiler's normal working range.
ATTENTION
From software version 23, an additional feature has been introduced to facilitate burner
calibration, i.e. flame flashing on the display to indicate that the burner is on but with in-
dication of non-optimal flame.
For the various software versions, the meanings of the symbols shown on the display
can be found in the table 3.
