– HEATING RETURN PROBE ANOMALY
"ALL 30" (fig. 23/24)
When the heating return probe (SR)
is open or short-circuited, the display
shows anomaly ALL 30. During such
anomaly the boiler continues normal
functioning.
– CASCADE DELIVERY SENSOR ANOMALY
"ALL 31" (fig. 23/25)
Apre
When the cascade delivery sensor (SMC)
is open or shorted, ALL 31 shall be di-
splayed.
During such anomaly, the boiler will con-
tinue to operate normally.
– THREE-ZONE SYSTEM CONFIGURATION
ANOMALY "ALL 32" (fig. 23/26)
2
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-
Apre
splayed. The boiler restarts when the
boiler three-zone system configuration
is activated
– RS-485 BOARD COMMUNICATION ANO-
MALY IN MODBUS MODE "ALL 33" (fig.

2
23/27)
When PAR 16 is different from "- -"and
there is no communication between the
boiler board and the RS-485 board in Circuito
riscaldamento 2
MODBUS mode for at least four minutes,
the boiler stops and anomaly ALL 33 is
displayed.
The boiler restarts when communication
Circuito
is restored or when PAR 16 = "- -" is set.

– RS-485 BOARD COMMUNICATION ANO-
MALY 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 CA-
SCADE mode, the boiler stops and ano-
maly ALL 34 is displayed.
The boiler restarts when communication
is restored or when PAR 15 = "- -" is set.
– RS-485 AND RS-485 COMMUNICATION
ANOMALY "ALL 35" (fig. 23/29)
Fig. 23/24
When PAR 15 is different from "- -" and
there is no communication between the
two RS-485 boards, the boiler stops and
Circuito
riscaldamento 2
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/casca-

de connection, error codes 70 and 71 will
appear on the SIME HOME remote control
display:
- ALARM 70
When an anomaly affects cascade ope-
ration (cascade delivery sensor ALL
31), SIME HOME remote control display
Circuito
will show alarm 70. Verify the anomaly riscaldamento 2
in the cascade.

- ALARM 71
When an anomaly occurs in one of the
Circuito

modules and the others keep operating
(impianto tre

2
to the extent permitted, the SIME HOME
remote control display will show alarm
71. Verify the anomaly in the cascade.
