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 occur:
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. On the display flash
"Err" and the error code (es.
Err/107).
In fact, soon as the cause of the shut-off
disappears, the boiler starts up again and
continues to operate normally.
While the boiler is shut off for safety reasons, it is possible to
attempt to restore normal operation by switching the appliance off
and on again using the ON/OFF button on the control panel.
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 qualified technician.
Safety shut-off due to insufficient water pressure
If the water pressure inside the heating circuit is
insufficient, the boiler will perform a safety shut-off.
On the display flash "Err" and the
code for Insufficient circulation
Check the water pressure on the pressure gauge and make sure
that is between 0.6 and1.5 bar when the system is cold. If the
pressure is just under the minimum refill the system by open the
valve under the boiler.
If the pressure drops very frequently, there may be a water leak at
some point in the system. If this is the case a plumber should be
contacted.
peration shutdown
This type of error is "non-volatile", which means that it is not
removed automatically. On the display flash Err and the error
code, and the red led "3"
In this case the boiler does not restart automatically, but it may
be reset by pressing the
itself again after several attempts to reset the appliance, contact a
qualified technician.
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 A PROBLEM.

Fune Sensor Error (CF Models)
Temporary Shut-Off due to defective flue gas discharge (CF)
601
This device causes the boiler to shut down in the event of an
anomaly in the flue gas discharge. The appliance shutdown is
temporary and is signalled by error code 601..
After 12 minutes, the boiler begins the ignition procedure; if normal
conditions have been restored, the boiler operates as normal. If
not, the boiler shuts down and the cycle is repeated.
WARNING!
In the event of a malfunction or if repeated intervention is
required, switch the boiler off, shut off the electricity supply
by turning the external switch to the OFF position and shut
off the gas valve. Contact the Technical Assistance Service or
a qualified technician in order to repair the flue gas discharge
fault once the cause of the malfunction is detected.
Anti-frost Device.
The anti-frost function acts on the central heating flow temperature
probe, independently from other regulations, when the electrical
supply is turned on.
If the primary circuit temperature falls below 8°C the pump will run
for 2 minutes.
After the two minutes of circulation (fixed) the boiler will check the
following:
a) if the central heating flow temperature is > 8°C, the pump stops;
b) if the central heating flow temperature is between 4 and 8°C, the
pump will run for another two minutes;
c) if the central heating flow temperature is < 4°C, the burner will
fire (heating position) at minimum power until the temperature
reaches 33°C, the burner will go out and the pump will continue
to run for two minutes.
The anti-frost device activates only when (with the boiler operating
correctly):
- the system pressure is correct;
