EXTERNAL SENSOR

(fig. 13)
If. there. is. an. external. sensor,. the. heating.
settings.SET.can.be.taken.from.the.climatic.
curves.according.to.the.external.tempera-
ture. and,. in. any. case,. limited. to. with. the.
range. values. described. in. point. 3.3. (para-
meters.PAR.22.for.zone.1,.PAR.25.for.zone.
2.and.PAR.28.for.zone.3)..
The.climatic.curve.to.be.set.can.be.selected.
from. a. value. of. 3. and. 40. (at. step. 1)..
Increasing. the. steepness. of. the. curves. of.
fig..13.will.increase.the.output.temperature.
as.the.external.temperature.decreases.
3.5 CARD FUNCTIONING
The.electronic.card.has.the.following.fun-
ctions:
–. Antifreeze.protection.of.the.heating.and.
sanitary.water.circuits.(ICE).
–. Ignition.and.flame.detection.system.
–. Control.panel.setting.for.the.power.and.
the.gas.for.boiler.functioning.
–. Anti-block.for.the.pump.which.is.fed.for.
a.few.seconds.after.24.hours.of.inactivi-
ty.
–. Antifreeze.protection.for.boilers.with.an.
accumulation.boiling.unit.
–. Chimney. sweep. function. which. can. be.
activated.from.the.control.panel.
–. Temperature. which. can. be. shifted. with.
the.external.sensor.connected..
. It.can.be.set.from.the.control.panel.and.
is.active.on.the.heating.systems.of.both.
circuit.1.and.circuit.2.and.3.
–. Management. of. 3. independent. heating.
circuit.systems.
–. Automatic. regulation. of. the. ignition.
power.and.maximum.heating...
. Adjustments. are. managed. automatical-
ly. by. the. electronic. card. to. guarantee.
maximum.flexibility.in.use.of.the.system.

3.7 ELECTRONIC IGNITION
Ignition.and.flame.detection.is.controlled.by.
a.single.electrode.on.the.burner.which.gua-
rantees. reaction. in. the. case. of. accidental.
extinction.or.lack.of.gas.within.one.second.
3.7.1 Functioning cycle
Burner. ignition. occurs. within. max.. 10.
seconds.after.the.opening.of.the.gas.valve..
Ignition. failure. with. consequent. activation.
of.block.can.be.due.to:
Lack of gas
–.
The. ignition. electrode. persists. in.
discharging. for. max.. 10. seconds.. If. the.
burner. does. not. ignite,. the. anomaly. is.
signalled.
. This.can.happen.the.first.time.the.boiler.
is.switched.on.after.a.long.period.of.inac-
tivity.due.to.the.presence.of.air.in.the.gas.
pipes
.. It.can.be.caused.by.a.closed.gas.tap.or.by.
a.broken.valve.coil.(the.interruption.does.
not.allow.for.opening)..
–. The electrode does not discharge.
. In.the.boiler,.only.the.opening.of.the.gas.
to. the. burner. can. be. detected.. After. 10.
seconds.the.anomaly.is.signalled..It.can.
be.caused.by.an.interruption.in.the.elec-
trode.wire.or.if.it.is.incorrectly.anchored.
to.the.connection.points..Or.the.electrode.
may.be.earthed.or.strongly.worn:.it.must.
be.replaced..
. Or.the.electronic.card.may.be.defective.
–. No flame detected
. After.start-up.the.electrode.continues.to.
discharge. even. when. the. burner. is. on..
After. 10. seconds,. the. discharge. stops,.
the. burner. is. switched. off. and. a. fault. is.
generated.
. This. fault. is. sometimes. caused. by. the.
shorting. of. the. electrode. cable. or. by. its.
improper.fixing.to.the.connection.points..
The. electrode. is. connected. to. the. earth.
or.badly.worn.and.must.be.replaced..The.
