– HEATING RETURN SENSOR ERROR
“ALL 30” (fig. 23/u)
When the heating return sensor (SR) is
open or shorted, ALL 30 will be displa-
yed.
During such anomaly, the boiler will
continue to operate normally.

– CASCADE DELIVERY SENSOR
ERRORS“ALL 31” (fig. 23/v)
In cascade systems, should the delive-
ry probe sensor(SMC) become open or
short circuited, the display will show
ALL31.
During such anomaly, the boiler will
continue to operate normally.

– THREE-ZONE SYSTEM CONFIGURA-
TION ERROR “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 restarts when the boiler
three-zone system configuration is ac-
tivated

– RS-485 BOARD COMMUNICATION ER-
ROR 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 minutes,
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 ERROR
IN CASCADE MODE “ALL 34” (fig. 23/j)
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 communication is
restored or when PAR 15 = “- -” is set.

– RS-485 AND RS-485 COMMUNICATION
ERROR “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 error ALL 35 is displayed. The boi-
ler restarts when communication is re-
stored or when PAR 15 = “- -” is set.
CAUTION: In the event of sequence/ca-
scade connection, error codes 70 and 71
will appear on the CR 73 remote control
display:

- ALARM 70
When an anomaly affects cascade
operation (cascade delivery sensor
ALL 31), CR 73 remote control display
will show alarm 70. Verify the ano-
maly in the cascade.
- ALARM 71
When an anomaly occurs in one of the
modules and the others keep opera-
ting to the extent permitted, the CR
73 remote control display will show
alarm 71. Verify the anomaly in the
cascade.
