–. PARASITE FLAME ANOMALY ALARM 08

(fig. 23/g)

If. the. flame. control. section. recognises.
the. presence. of. flames. also. in. phases.
when.they.should.not.be.present,.it.me-
ans. there. is. a. breakdown. in. the. flame.
detection.circuit;.the.boiler.will.stop.and.
the.display.will.show.anomaly.“ALL.08”.

–. WATER

CIRCULATION

ANOMALY

ALARM 09 (fig. 23/h)

There.is.no.water.circulation.in.the.pri-
mary.circuit..If.the.anomaly.occurs.upon.
first.request,.the.boiler.performs.a.ma-
ximum. of. three. attempts. to. assure. the.
presence. of. water. inside. the. primary.
circuit;.it.then.stops.showing.on.the.di-
splay.the.ALL.09.anomaly..If.the.anomaly.
occurs. during. normal. functioning,. the.
display. immediately. shows. the. ALL. 09.
anomaly,. keeping. the. plant. pump. and.
the. eventual. boiler. pump,. switched. on.
for.1.minute..

In.this.case.there.was.a.sudden.increase.
of. the. boiler. inner. temperature.. Check.
to.see.if.there.is.water.circulation.inside.
the.boiler.and.check.if.the.pump.is.ope-
rating.properly.

. To.exit.the.anomaly.press.the.

..but-

ton. of. the. controls. (2).. If. the. anomaly.
persists,.request.assistance.from.quali-
fied.technical.personnel..

–. AUXILIARY SENSOR ANOMALY ALARM

10 (fig. 23/l)

BOILER. WITH. ACCUMULATION:. ano-
maly.of.the.D.H.W..sensor.(SB)..When.the.

D.H.W..sensor.is.open.or.short.circuited,.
the.display.will.show.anomaly.“ALL.10”..
The.boiler.will.function.but.will.not.mo-
dulate.power.for.the.D.H.W.

BOILER.ONLY.FOR.HEATING:.antifreeze.
sensor. anomaly. for. boilers

which. fore-

see.the.use.of.antifreeze.sensors.

. When.the.sensor.is.open.or.short.circu-

ited,.the.boiler.loses.part.of.its.anti-fre-
eze. functions. and. the. display. will. show.
anomaly.“ALL.10”.

BOILER. COMBINED. WITH. SUN-PANEL.
SYSTEM:. anomaly. of. the. D.H.W.. input.
sensor..When.the.sensor.is.open.or.short.
circuited,.the.boiler.loses.the.sun-panel.
function.and.the.display.will.show.ano-
maly.“ALL.10”..

–. ACTIVATION OF THE “ALL 13” EXHAUST

FUMES PROBE (fig. 23/p)

The. activation. of. this. probe. causes. the.
boiler. to. stop. and. error. message. “ALL.
13”.to.display..

. Press.the.key

of.the.controls.(2).to.

start.up.the.boiler.again.

–. “ALL 14” EXHAUST FUMES PROBE ER-

ROR (fig. 23/q)

. If. the. exhaust. fumes. probes. is. open. or.

short-circuited,.the.boiler.stops.and.er-
ror.message.“ALL.14”.displays.

–. “ALL 15” FAN ERROR (fg. 23/r)
. The.fan.speed.does.not.fall.within.the.ra-

ted.speed.range..If.the.error.conditions.
persists.for.two.minutes,.the.boiler.ac-
tivates. a. forced. stop. for. thirty. minutes..
A.new.start.attempt.is.repeated.after.the.
expiry.of.this.interval.of.time.

–. SAFETY THERMOSTAT INTERVENTION
