Conditions for switching off the appliance
The boiler is protected from malfunction by the electronic board that
performs certain internal controls, which triggers, if necessary, a
safety locking device. In the event of a blockage, the control panel
display shows a code referring to the type of stop and the cause that
caused the stop.
They can be verified as two types of stops.
Safety stop
This error is of the "volatile" type, ie it disappears
automatically immediately afterwards
cessation of the cause that caused the arrest.
ERR and error code (eg Err / 110) appear on
the display and the symbol appears
- see table.
Immediately after the end of the cause that caused this shutdown,
the device restarts and starts operating normally.
While the boiler is in safe stop, you may want to try restarting it by
turning the unit off and on again from the control panel.
Safety shutdown due to insufficient water
pressure In case of insufficient water circulation
in the heating circuit, the boiler signals safety
shutdown Err / 108 - see Error table.
Check the pressure on the pressure gauge
and close the valve as soon as it reaches 1 -
1.5 bar.
The system can be restored by filling it with water from the filling
valve under the boiler.
If the level request is frequent, switch off the boiler, set the external
electrical switch to the OFF position, turn off the gas valve and call a
qualified installer to check for water leaks.
Operation lock
This "non-volatile" error disappears even
after eliminating the cause that caused the plant to shut down.
ERR and error code appear on the display (eg

Err / 501).
Important
If the shutdown is repeated frequently, we recommend that you contact an
authorized Technical Assistance Center. For safety reasons, the boiler will in
any case allow a maximum of 5 reset attempts in 15 minutes (by pressing the
RESET key). If the boiler rarely shuts down, this is not a problem.
The first digit of the error code (eg 1 01) shows the group in which
the anomaly occurred:
1 - Primary Circuit
2 - Sanitary Circuit
3 - Internal Electronic Part
4 - External Electronic Part
5 - Ignition and Detection
6 - Air supply - Flue gas exhaust
Warning of malfunction
This announcement appears on the display as follows:
5 P1 = first ignition attempt failed
the first digit (showing the group where the anomaly occurred) is
followed by the letter P (ad) and the code for that ad.
Circulator malfunction notice
There is an LED on the circulator that indicates the status of
operation:
Led stins:
The circulator is not powered.
Green LED fi x:
