4.6 FUNCTIONING ANOMALIES
ES
When there is a functioning anomaly, an
PT
alarm appears on the display and the blue
luminous bar becomes red.
Descriptions of the anomalies with relative
GB
alarms and solutions are given below:
– FUMES DISCHARGE
ALARM 01 (fig. 24)
OPEN BOILER (OF/OFT):
The display shows "ALL 01".
The fumes thermostat has intervened.
The boiler stops for an enforced period
of 10 minutes. At the end of this period,
the boiler re-attempts ignition. If the ano-
maly is repeated three times in 24
hours, the symbol RESET starts flashing.
Press the key
to start up the boiler again.
SEALED BOILER (BF/BFT):
The fumes thermostat has intervened. If
the condition causing the problem persi-
sts for two minutes, the boiler stops for
an enforced period of thirty minutes. At
the end of this period, the boiler re-
attempts ignition.

– LOW WATER PRESSURE ANOMALY
ALARM 02 (fig. 24/a)
If the pressure detected by the transdu-
cer is lower than 0.5 bar, the boiler
stops and the display shows the alarm
"ALL 02".
Bring the pressure back to normal by
means of the load faucet (turn anti-
clockwise to open) until the pressure
indicated by the transducer is between 1
and 1.5 bars.
ON COMPLETION OF THE OPERATION,
MAKE SURE THE LOAD FAUCET IS CLO-
SED
If the load procedure has to be repeated
several times, it is advisable to check
100
that the seal of the heating circuit is
intact (check that there are no leaks).

– HIGH WATER PRESSURE ANOMALY
ALARM 03 (fig. 24/b)
If the pressure detected by the transdu-
cer is more than 2.8 bar, the boiler
stops and the display shows anomaly
"ALL 03"

– D.H.W. SENSOR ANOMALY ALARM 04
(fig. 24/c)
If the D.H.W. sensor (SS) is open or
short circuited, the boiler will function
but will not modulate the power for sani-
tary water. The display will show the
alarm "ALL 04".
– HEATING SENSOR ANOMALY ALARM
05 (fig. 24/d)
If the heating sensor (SM) is open or
short circuited, the boiler will not func-
tion and the display will show the alarm
"ALL 05".
– FLAME BLOCK ALARM 06 (fig. 24/e)
If the flame control has not detected the
presence of the flame after a complete
ignition sequence, or for any other rea-
son the card cannot "see" the flame, the
boiler will stop and the display will show
the alarm "ALL 06".
Press the key
start up the boiler again.

– SAFET Y THERMOSTAT ANOMALY
ALARM 07 (fig. 24/f)
If the connection with the safety thermo-
stat is interrupted, the boiler will stop;
the flame control will remain waiting to
be switched off for one minute, keeping
the system pump on for that period.
If, the thermostat connection is restored
within the minute, the boiler will start up
working normally again, otherwise it will
stop and the display will show the alarm
