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
o in this manner, a code appears on the control panel display
which refers to the type of shut-o and the reason behind it.
Two types of shut-o may occur:
This type of error is “volatile”, which means
that the boiler starts up again automatically
as soon as the problem which caused the
shut-o is removed;
and the error
code
(e.g. / ) ash on the
display and the symbol appears.
In fact, soon as the cause of the shut-o
disappears, the boiler starts up again and
continues to operate normally.
If the boiler still indicates a safety shut-o,
switch it o. Make sure the external electric
switch is in the OFF position, shut o the gas valve and contact a
qualied technician.
If the water pressure inside the heating circuit is insucient, the
boiler will perform a safety shut-o.
Code 108 (
/ ) will appear on
the display.
The system may be restarted, re-balancing
the water pressure, by using the lling
procedure - see note 1.
If the re-balancing request is performed
on a frequent basis, switch the boiler o,
bring the external electric switch to the OFF
position, shut o the gas valve and contact
a qualied technician to check for any leaks
of water.
Important
If this shutdown occurs frequently, contact an authorised
service centre for assistance. For safety reasons, the boiler
will allow a maximum of 5 reset operations to take place in 15
minutes (individual presses of the button).
If the shutdown is occasional or an isolated event, this is not
Necessarily a problem.
Anti-frost Device.
The anti-frost function acts on the central heating ow temperature pro-
be, independently from other settings, when the electrical supply is tur-
ned on. If the primary circuit temperature falls below 8°C the pump will
run for 2 minutes.
After the two minutes of circulation (xed) the boiler will check the fol-
lowing:
a - if the central heating ow temperature is > 8°C, the pump stops;
b - if the central heating ow temperature is between 4 and 8°C, the
pump will run for another two minutes;
c - if the central heating ow temperature is
< 4°C, the burner will re (heating posi-
tion) at minimum power until the tempe-
rature reaches 33°C, the burner will go o
and the pump will continue to run for two
minutes.
The activation of the Anti-Frost feature is
symbolised by
.
The anti-frost device activates only when (with
the boiler operating correctly):
- the system pressure is correct;
- the boiler is electrically powered;
- there is a supply of gas.

Operation shutdown
This type of error is “non-volatile”, which means that it is not
removed automatically.
On the display ash
and the error code
,
e.g.
Err/501
and appears the symbol
.
In this case the boiler does not restart automatically, but it may be
reset by pressing the
button.
If the problem manifests itself again after several attempts to
reset the appliance, contact a qualied technician.
