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 use the RESET on the Remote Timer Control (optional) if
installed; if the boiler fails to start, it is necessary to eliminate the fault indicated by the operation LEDs.
Other faults cause temporary shutdowns (marked with the letter “
F ” with operation automatically restored as soon as
the value returns within the boiler's normal operating range.
