The.set.of.the.mixed.zone.follows.the.deve-
lopment.of.the.selected.curve.and.reaches.
a. maximum. of. 55°C.. During. the. function.
all.the.other.heating.demands.are.ignored.
(heating,. sanitary,. antifreeze. and. chimney.
sweep)..
During. the. functioning. the. display. shows.
the. remaining. days. for. the. completion. of.
the.function.(example.mains.digits.-15.=.15.
days. lack. to. the. end. of. the. function).. The.
diagram.fig..21/a.reports.the.development.
of.the.curve.
ATTENTION:
- Observe the relevant standards and
regulations of the floor manufacturer!
- Proper functioning is ensured only
when the plant is correctly installed
(hydraulic system, electrical installa-
tion, settings)! If not observed, the floor
might get damaged!

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:
–. FUMES DISCHARGE ANOMALY “ALL 01” .
(fig. 24)
. Intervention. of. the. smoke. thermostat..
The. boiler. stops. for. 10. minutes.. At. the.
end.of.the.period,.the.boiler.reattempts.
ignition.
. If. the. anomaly. is. repeated. three. times.
over. 24. h,. the. symbol. RESET. starts.
flashing..Press.the.key.

panel.(2).to.start.up.the.boiler.
–. LOW WATER PRESSURE ANOMALY
“ALL 02” (fig. 24/a)
. If.the.pressure.detected.by.the.transdu-
cer.is.less.than.0.5.bar,.the.boiler.stops.
and. the. display. will. show. anomaly. ALL.
02..
. When.the.system.is.cold,.proceed.to.re-
store.the.pressure.acting.on.the.loading.
tap. (externally. mounted. by. the. instal-
ler). until. the. pressure. indicated. by. the.
transducer.goes.between.1.and.1.5.bar.
.
. WHEN.FILLING.HAS.BEEN.COMPLETED.
TURN. OFF. THE. EXTERNAL. LOADING.
TAP.
.
. If the load procedure has to be repeated
several times, it is advisable to check
that the seal of the heating circuit is in-
tact (check that there are no leaks).
–. HIGH WATER PRESSURE ANOMALY
ALARM 03 (fig. 24/b)
. If.the.pressure.detected.by.the.transdu-
cer.is.more.than.3.8.bar,.the.boiler.stops.
and.the.display.shows.anomaly.“ALL.03”.
–. 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.
not.modulate.the.power.for.D.H.W..The.
display.will.show.the.alarm.“ALL.04”.
–. HEATING SENSOR ANOMALY ALARM 05
(fig. 24/d)
. If. the. heating. sensor. (SM). is. open. or.
short. circuited,. the. boiler. will. not. fun-
