The boiler is protected from malfunctioning by means of internal
checks by the P.C.B., which brings the boiler to a stop if necessary.
In the event of the boiler being shut off in this manner, a code
appears on the display which refers to the type of shut-off and the
reason behind it.
There are two types of shut-off:
-
SAFETY SHUTDOWN:
for this group of errors (characterised
on the display by the letter “
E
E
”) the situation is automatically
removed as soon as the cause behind it is resolved.
As soon as the origin of the shutdown disappears, the boiler
starts up again and returns to its normal operation.
-
SHUTDOWN:
(characterised on the display by the letter “
A
A
”), is
not removed unless a manual intervention is made.
The boiler may return to operation only if reset, press the
button located at the centre of the display.
There follows a list of the shutdown modes and the respective codes
shown on the display.
Shutdown (“
A
A
” type): if such a situation occurs, it is necessary to
reset the boiler using the appropriate key. If this shutdown occurs
frequently, your local Service Agent should be contacted.
Safety shutdown: In the event that a safety shutdown occurs, it is
necessary to contact an Authorised Service Centre.
