4.6 FUNCTIONING ANOMALIES
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:
–. FUMES DISCHARGE ANOMALY ALARM
01 (fig. 24)
. OPEN.COMBUSTION.CHAMBER.(OF):
. 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

SEALED.COMBUSTION.CHAMBER.(BF): .
. The.fumes.thermostat.has.intervened..If.
the. condition. causing. the. problem. per-
sists. 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.me-
ans.of.the.load.faucet.(turn.anticlockwise.
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.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”.
–. HEATING SENSOR ANOMALY ALARM 05
(fig. 24/d)
. If.the.heating.sensor.(SM).is.open.or.short.
circuited,.the.boiler.will.not.function.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 .

of.the.controls.(2).to.
start.up.the.boiler.again.
–. SAFETY 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.
“ALL.07”.

the. presence. of. flames. also. in. phases.
