ACTIVATION OF THE “ALL 13”
EXHAUST FUMES PROBE (fig. 23/10)
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. 23/11)
If the exhaust fumes probes is open or
short-circuited, the boiler stops and er-
ror message ALL 14 displays.
–
“ALL 15” FAN ERROR (fig. 23/12)
The fan speed does not fall within the
rated speed range. If the error condi-
tions persists for two minutes, the boi-
ler activates a forced stop for thirty mi-
nutes. A new start attempt is repeated
after the expiry of this interval of time.
–
EXTERNAL PROBE ANOMALY “
FLASHING” (fig. 23/13)
When the external probe (SE) is short-
circuited, the display the symbol
flashes
. During such anomaly he
boiler continues normal functioning.
–
SAFETY THERMOSTAT INTERVEN-
TION FIRST MIXED ZONE “ALL 20” (fig.
23/14)
When it results that the ZONA MIX bo-
ard is connected to the boiler the safety
thermostat intervention switches the
mixed zone plant pump, the mix zone
valve closes and on the display the ano-
maly ALL 20. During this anomaly the
boiler continues to function normally.
–
DELIVERY PROBE BREAKDOWN ANO-
MALY FIRST MIXED ZONE “ALL 21”
(fig. 23/15)
When it results that the ZONA MIX bo-
ard is connected to the boiler and the
delivery probe is open or short circuited
on the display the anomaly ALL 21 ap-
pears. During this anomaly, the boiler
continues to function normally.
–
SAFETY THERMOSTAT INTERVENTION
SECOND MIXED ZONE “ALL 22” (fig.
23/16)
When it results that the ZONA MIX bo-
ard is connected to the boiler
The intervention of the safety ther-
mostat switches the mixed zone plant
pump, the mix zone valve closes and on
the display the anomaly ALL 22. During
this anomaly the boiler continues to
function normally.
–
DELIVERY PROBE BREAKDOWN ANO-
MALY SECOND MIXED ZONE “ALL 23”
(fig. 23/17)
When it results that the ZONA MIX bo-
ard is connected to the boiler and the
delivery probe is open or short circuited
on the display the anomaly ALL 23 ap-
pears.
During this anomaly the boiler conti-
nues to function normally.
–
SOLAR COLLECTOR SENSOR ANO-
MALY (S1) “ALL 24” (fig. 23/18)
When the solar probe is open or short
circuited, on the display the anomaly
ALL 24 appears. During this anomaly
the boiler continues to function nor-
mally but loses the solar function that
is no longer available.
–
SOLAR PROBE ANOMALY STORAGE
TANK (S2) “ALL 25” (fig. 23/19)
When the solar probe is open or short
circuited, on the display the anomaly
ALL 25 appears. During this anomaly
the boiler continues to function nor-
mally but loses the solar function that
is no longer available.
–
AUXILIARY SENSOR ANOMALY (S3)
“ALL 26” (fig. 23/20)
When the solar probe is open or short
circuited, on the display the anomaly
ALL 26 appears. During this anomaly
the boiler continues to function nor-
mally but loses the solar function that
is no longer available.
