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:
–. LOW WATER PRESSURE
ANOMALY ALARM 02 (fig. 23/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.until.the.pres-
sure. 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. 23/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. 23/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. 23/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”..

of.the.controls.(2).to.
start.up.the.boiler.again.
–. SAFETY THERMOSTAT
ANOMALY ALARM 07 (fig. 23/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.
when.they.should.not.be.present,.it.me-
