4.5.4 Error messages
The boiler is equipped with a self-diagnostics system in or-
der to help the maintenance personnel identify the causes
of any anomalies.
When a technical anomaly occurs, the display on the left
will either show the letter "A" or the letter "E", while the dis-
play on the right will show a numeric error code, which will
allow the maintenance personnel to identify the possible
cause.
- If the letter "A" appears on the left-hand display, this
means that the "RESET" button will have to be pressed
after the cause of the fault has been eliminated.
- If the letter "E" appears on the left-hand display, this
means that the boiler will resume functioning normal-
ly, without having to press the "RESET" button, once
the cause of the fault has been eliminated.
The list of the error codes and the descriptions of the rela-
tive anomalies are provided below:
Error
type
Description
A 01 No flame.
A 02
The burner turned off three times during a
request for heat.

those of the main software. Replace the circuit
board.
A 13
There has been a type "E" error that has not
been reset for more than 24 hours.
A 14
Internal software error. Replace the circuit
board.
A 15
Internal software error. Replace the circuit
board.
A 16
Internal software error. Press the reset key.
If the error is permanent replace the circuit
board.
A 17
Internal software error. Replace the circuit
board.
A 18
The flame was still detected after more than
10 seconds from the closure of the gas valve.
Press the reset key.
If the error is permanent replace the circuit
board.
A 19
The presence of a flame is detected more
than 10 seconds after the closure of the gas
valve.
Error
type
Description
A 20
Flame detected before the opening of the gas
valve. Press the reset key.
