When there is a functioning anomaly, an
alarm appears on the display
and the blue
luminous bar becomes red.
Descriptions of the anomalies with relative
alarms and solutions are given below:
–
LOW WATER PRESSURE ANOMALY
ALARM 02 (fig. 23/1)
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. Lower the knob and turn it anti-
clockwise to open until the pressure in-
dicated by the transducer is between 1
and 1.5 bars.
If the load procedure has to be repeated
several times, it is advisable to check
that the seal
of the heating circuit is in-
tact (check that there are no leaks).
–
HIGH WATER PRESSURE ANOMALY
ALARM 03 (fig. 23/2)
If the pressure detected by the transdu-
cer is more than 4.8 bar, the boiler stops
and the display shows anomaly ALL 03.
–
C.H. FLOW SENSOR ANOMALY ALARM
05 (fig. 23/4)
If the C.H. flow sensor (SM) is open or
short circuited, the boiler will not fun-
ction and the display will show the alarm
ALL 05.
–
FLAME BLOCK ALARM 06 (fig. 23/5)
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.
