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 ano-
maly in the cascade.
