– “ALL 15” FAN ERROR (fig. 23/12)
The fan speed does not fall within the
rated speed range.
If the error conditions persists for two
minutes, the boiler activates a forced
stop for thirty minutes.
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 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.
– ANOMALY SOLAR APPLICATION COM-
PATIBILITY “ALL 27” (fig. 23/21)
When the hydraulic configuration is not
consistent with the selection solar appli-
cation, on the display the anomaly ALL
27 appears. During this anomaly the boi-
ler continues to function normally but for
the board is active in the solar anomaly,
the function is only available antifreeze
collector.
– COMPATIBILITY INPUT (S3) ANOMALY
ONLY FOR SYSTEM 7 “ALL 28” (fig.
23/22)
When a probe is connected instead of a
clean contact on entry S3 the board on
display shows the anomaly ALL 28.
During this anomaly the boiler continues
to function normally but for the board is
active in the solar anomaly, the function
is only available antifreeze collector.
– ANOMALY NUMBERS REL ATED
BOARD “ALL 29” (fig. 23/23)
When one of t he boar d ZONA
MIX/INSOL failure or does not communi-
cate, the display shows anomaly ALL 29.
The boiler functional excluding the func-
tion ZONE MIX/INSOL.
