PATIBILITY “ALL 27” (fig. 23/21)
When the hydraulic configuration is
not consistent with the selection solar
application, on the display the anomaly
ALL 27 appears. During this anomaly
the boiler continues to function nor-
mally but for the board is active in the
solar anomaly, the function is only avai-
lable 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. Du-
ring 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 RELATED BO-
ARD “ALL 29” (fig. 23/23)
When one of the board ZONA MIX/IN-
SOL failure or does not communicate,
the display shows anomaly ALL 29. The
boiler functional excluding the function
ZONE MIX/INSOL.
–
HEATING RETURN SENSOR ANOMALY
“ALL 30” (fig. 23/24)
When the heating return sensor (SR) is
open or shorted, ALL 30 shall be displa-
yed.
During such anomaly, the boiler will
continue to operate normally.
–
CASCADE DELIVERY SENSOR ANO-
MALY “ALL 31” (fig. 23/25)
When the cascade delivery sensor
(SMC) is open or shorted, ALL 31 shall
be displayed. During such anomaly, the
boiler will continue to operate normal-
ly.
–
THREE-ZONE SYSTEM CONFIGURA-
TION ANOMALY “ALL 32” (fig. 23/26)
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 di-
splayed.
The boiler restarts when the boiler
three-zone system configuration is ac-
tivated.

RS-485
BOARD
COMMUNICATION
ANOMALY IN MODBUS MODE “ALL 33”
(fig. 23/27)
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 communica-
tion is restored or when PAR 16 = “- -”
is set.
–
RS-485
BOARD
COMMUNICATION
ANOMALY IN CASCADE MODE “ALL 34”
(fig. 23/28)
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 COMMUNICATION
ANOMALY “ALL 35” (fig. 23/29)
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.
CAUTION: In the event of sequence/ca-
scade connection, error codes 70 and 71
will appear on the SIME HOME remote
control display:
- ALARM 70
When an anomaly affects cascade
operation (cascade delivery sensor
ALL 31), SIME HOME remote control
display will show alarm 70. Verify the
anomaly in the cascade.
- ALARM 71
When an anomaly occurs in one of the
modules and the others keep ope-
rating to the extent permitted, the
SIME HOME remote control display
will show alarm 71. Verify the anomaly
in the cascade.
