ACTIVATION OF THE “ALL 13” EXHAU-
ST 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
ERROR (fig. 23/11)
If the exhaust fumes probes is open or
shor t-circuited, the boiler stops and
error 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 boiler
activates a forced stop for thirty minu-
tes. 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 con-
tinues normal functioning.
–
SAFETY THERMOSTAT INTERVENTION
FIRST MIXED ZONE “ALL 20” (fig.
23/14)
When it results that the ZONA MIX
board 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
board is connected to the boiler and the
delivery probe is open or short circuited
on t he display t he anomal y ALL 21
appears.
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
board is connected to the boiler
The intervention of the safety thermo-
s t at 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 func-
tion normally.
–
DELIVERY PROBE BREAKDOWN ANO-
MALY SECOND MIXED ZONE “ALL 23”
(fig. 23/17)
When it results that the ZONA MIX
board is connected to the boiler and the
delivery probe is open or short circuited
on the display the anomaly ALL 23
appears.
During this anomaly the boiler continues
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 boi-
ler continues to function normally 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 boi-
ler continues to function normally 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 boi-
ler continues to function normally but
loses the solar function that is no longer
available.
