REGULATION OF THE WATER TEMPERATU-
RE FOR HEATING (fig. 26)

To.set.the.temperature.of.the.water.for.hea-
ting,. press. the. key

of. the. controls. (2)..

The.first.time.the.key.is.pressed,.the.SET.of.
heating.circuit.1.is.selected..
The.second.time.it.is.pressed,.the.SET.of.he-
ating.circuit.2.is.selected..The.display.will.be.
as. shown. in. the. figure.. Change. the. values.
with.the.key

and.

Standard.visualisation.will.return.to.the.di-
splay.by.pressing.the.key.

again,.or.after.

10.seconds.if.no.key.is.pressed.

Regulation of the external sensor (fig.
26/a)
If.an.external.sensor.is.installed,.the.value.
of. the. output. temperature. is. automatically.
chosen.by.the.system,.which.quickly.adjusts.
the.environmental.temperature.on.the.basis.
of.the.external.temperature..If.you.wish.to.
change. the. value. of. the. temperature,. in-
creasing. or. decreasing. that. calculated. au-
tomatically.by.the.electronic.card,.proceed.
as. indicated. in. the. preceding. paragraph..
The.level.of.various.correction.of.a.value.of.
temperature. proportional. calculated.. The.
display.will.be.as.shown.in.fig..26/a.

REGULATION OF THE D.H.W.
TEMPERATURE (fig. 27)

To. set. the. desired. temperature. D.H.W.,.
press.the.key

of.the.controls.(pos..2)..The.

display.will.be.as.shown.in.the.figure.
Change. the. values. with. the. key

and.

.The.display.will.return.to.the.standard.

TO SWITCH OFF THE BOILER (fig. 25)

In.the.case.of.a.short.absence,.press.the.key

of.the.controls.(pos..2)..The.display.will.

be.as.shown.in.the.figure.25..In.this.way,.le-
aving.the.electricity.and.the.fuel.supply.con-

nected,. the. boiler. is. protected. from. frost.
and.from.the.pump.becoming.blocked..If.the.
boiler.is.not.used.for.a.prolonged.period,.it.is.
advisable.to.disconnect.the.electricity.sup-
ply,.by.switching.off.the.main.switch.of.the.
system,.and.to.close.the.gas.tap.and,.if.low.
temperatures. are. expected,. to. completely.
empty. the. hydraulic. circuits. to. avoid. pipes.
being.broken.by.the.formation.of.ice.in.the.
pipes.

ANOMALIES AND SOLUTIONS
When. there. is. a. functioning. anomaly,. the.
display.shows.an.alarm.and.the.blue.lumi-
nous.bar.becomes.red..Descriptions.of.the.
anomalies.with.the.relative.alarms.and.so-
lutions.are.given.below:

–. ALL 01 (fig. 28)

Press.the.key

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

re-start.the.boiler..

. If the anomaly persists, request the in-

tervention of qualified technical person-
nel.

–. ALL 02 (fig. 28/a)

If. the. water. pressure. detected. is. lower.
than.0.5.bar,.the.boiler.will.stop.and.the.
display.will.show.“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 it is necessary to repeat the system

loading procedure, it is advisable to
contact qualified technical personnel to
check the seal of the heating system (to
check whether there are any leaks).

. Request assistance from qualified tech-

nical personnel.

–. ALL 06 (fig. 28/c)
. Press.the.key

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