Appliance shut-off conditions
The boiler is protected from malfunctions by means of internal checks
performed by the electronic P.C.B., which stops the boiler from operating
if necessary. In the event of the boiler being shut off in this manner, a
code appears on the control panel display which refers to the type of
shut-off and the reason behind it.
Two types of shut-off may occu
r:
Safety shut-off
This type of error is “volatile”, which means that the boiler starts up
again automatically as soon as the problem which caused the shut-off
is removed.
The display shows the code and the error description.
“Fault 110 - SendProbeDamaged”
In fact, soon as the cause of the shut-off disappears, the boiler starts up
again and continues to operate normally.
If the boiler still indicates a safety shut-off, switch it off. Make sure the
external electric switch is in the OFF position, shut off the gas valve and
contact a qualied technician.
Safety shut-off due to insufcient water pressure
In caso di insufciente pressione dell’acqua nel circuito riscaldamento
la caldaia segnala un arresto di sicurezza.
The display shows
“Fault 108 - FillingNeeded”.
The system may be restarted, re-balancing the water pressure, by
using the filling procedure - see note 1.
If the re-balancing request is performed on a frequent basis, switch
the boiler off, bring the external electric switch to the OFF position,
shut off the gas valve and contact a qualified technician to check for
any leaks of water.
Operation shutdown
This type of error is “non-volatile”, which means that it is not removed
automatically.
The display shows the code and the error description.
To restore normal operation press the RESET button on the control
panel.
The dispay shows
“Resetinprogress” and then “Faultsolved”.
If the problem manifests itself again after several attempts to reset the
appliance, contact a qualied technician.

Important
If this shutdown occurs frequently, contact an authorised Technical
Service Centre for assistance. For safety reasons, the boiler will permit
a maximum of 5 resets in 15 minutes (5 presses of the RESET button);
at the 6th attempt within this 15-minute period the boiler will shut down
and may only be operated again after the electricity supply has been
disconnected. If the shutdown is occasional or an isolated event, this is
not a problem.
