4.6 FUNCTIONING ANOMALIES
APRE
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
2
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
2
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 com-
plete ignition sequence, or for any
other reason the card cannot "see" the
flame, the boiler will stop and the di-
splay will show the alarm ALL 06.
Press the key
to start up the boiler again.
