function ZONE MIX/SOLAR.
– 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 ANO-
MALY "ALL 31" (fig. 23/25)
APRE
When the cascade delivery sensor
(SMC) is open or shorted, ALL 31 shall
be displayed.
During such anomaly, the boiler will
continue to operate normally.

– 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 configura-
APRE
tion is activated

ANOMALY IN CASCADE MODE "ALL
34" (fig. 23/28)
When PAR 15 is different from "- -"
and there is no communication betwe-
en the boiler board and the RS-485 bo-
ard in CASCADE mode, the boiler stops
and anomaly ALL 34 is displayed.
The boiler restarts when communica-

When PAR 15 is different from "- -"
and there is no communication betwe-

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
Fig. 23/26
ALL 31), SIME HOME remote control
display will show alarm 70. Verify the
anomaly in the cascade.
COMMUNICATION
- ALARM 71
When an anomaly occurs in one of the
2
modules and the others keep ope-
2
rating to the extent permitted, the
SIME HOME remote control display
will show alarm 71. Verify the ano-
maly in the cascade.
