3.4 Troubleshooting
Diagnostics
The boiler has 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 shutdowns (marked with the letter "
A
"): to restore operation, press the RESET
button (detail 6 - fig. 1) for 1 second or RESET on the optional remote timer control if installed. At this point the display
will show
“d4”
for about
30 seconds
or
“d5”
for about
5 minutes
which indicates the waiting time after which the boiler
will resume normal operation. if the boiler fails to restart, it is necessary to eliminate the fault.
Other faults cause temporary shutdowns (marked with the letter “
F
”) which are automatically reset as soon as the value
returns within the boiler's normal working range.
