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.
2
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-
5
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-

–. 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.
