3.4 Troubleshooting
Diagnostics
The boiler is equipped with an advanced self-diagnosis system. In case of a boiler anomaly, the display will flash to-
gether 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 just turn the selector
(detail 3 - fig. 1) to RESET (detail 8 - fig. 1) for 1 second or by means of the RESET on the Remote Timer Control (op-
tional) if installed; if the boiler fails to start, it is necessary to eliminate the fault indicated by the operation LEDs.
Faults marked with the letter “ F ” cause temporary shutdowns that are automatically reset as soon as the value returns
within the normal boiler operation range.
