– "ALL 15" FAN ERROR (fig. 23/m)
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/p)
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/q)
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/r)
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 21
appears.
During this anomaly, the boiler continues
to function normally.

– SAFETY THERMOSTAT INTERVENTION
SECOND MIXED ZONE "ALL 22" (fig.
23/s)
When it results that the ZONA MIX
board is connected to the boiler
The intervention of the safety thermo-
stat 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/t)
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.

– HEATING RETURN SENSOR ANOMALY
"ALL 30" (fig. 23/u)
When the heating return sensor (SR) is
open or shor t ed, ALL 30 shall be
displayed.
During such anomaly, the boiler will conti-
nue to operate normally.
Fig. 23/u
– CASCADE DELIVERY SENSOR ANO-
MALY "ALL 31" (fig. 23/v)
When the cascade deliver y sensor
(SMC) is open or shorted, ALL 31 shall
be displayed.
During such anomaly, the boiler will conti-
nue to operate normally.

– THREE-ZONE SYSTEM CONFIGURA-
TION ANOMALY "ALL 32" (fig. 23/w)
When the boards connected to the RS-
485 are not enough and/or at least one
of them it is not mixing zone board, the
boiler stops and anomaly ALL 32 is
displayed.
The boiler restar ts when the boiler
three-zone system configuration is acti-
vated
– RS-485 BOARD COMMUNICATION
ANOMALY IN MODBUS MODE "ALL
33" (fig. 23/k)
When PAR 16 is different from "- -"and
there is no communication between the
boiler board and the RS-485 board in
MODBUS mode for at least four minu-
tes, the boiler stops and anomaly ALL
33 is displayed.
The boiler restarts when communication
is restored or when PAR 16 = "- -" is set.
– RS-485 BOARD COMMUNICATION
ANOMALY IN CASCADE MODE "ALL
34" (fig. 23/j)
When PAR 15 is different from "- -" and
there is no communication between the
boiler board and the RS-485 board in
CASCADE mode, the boiler stops and
anomaly ALL 34 is displayed. The boiler
restarts when communication is resto-
red or when PAR 15 = "- -" is set.
– RS-485 AND RS-485 COMMUNICA-
TION ANOMALY "ALL 35" (fig. 23/x)
When PAR 15 is different from "- -" and
there is no communication between the
two RS-485 boards, the boiler stops and
anomaly ALL 35 is displayed. The boiler
restarts when communication is resto-
red or when PAR 15 = "- -" is set.
