4.5 FUNCTIONING ANOMALIES
2
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.minu-
2
tes.. At. the. end. of. this. period,. the. boiler.
re-attempts.ignition..If.the.anomaly.is.re-
peated. three. times. in. 24. hours,. the.
symbol.RESET.starts.flashing..Press.the.
key.
the.boiler.again.
.
. SEALED.COMBUSTION.CHAMBER
.. (BF/BFT):.
. 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-
2
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.ac-
ting.on.the.loading.knob..Lower.the.knob.
and. turn. it. anti-clockwise. to. open. until.
the. pressure. indicated. by. the. display. is.
between.1.and.1.5.bars..
. WHEN. FILLING. HAS. BEEN. COMPLE-
TED,. CLOSE. THE. KNOB. BY. TURNING. IT.
CLOCKWISE.
. If.the.load.procedure.has.to.be.repeated.
several.times,.it.is.advisable.to.check.that.

–. D.H.W. SENSOR ANOMALY ALARM 04
(fig. 24/c)
. If.the.D.H.W..sensor.(SS).is.open.or.short.
circuited,.the.boiler.will.function.but.will.

–. 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.reason.

–. 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.
