Write
7 SIGN R/W Sign bit All registers have 2’s complement format.
The offset range for each remote is
6 32 R/W bit weight 32°C
+63.5°C/−64°C. The value programmed in
5 16 R/W bit weight 16°C
this register is directly added to the actual
reading of the ADC and the modified number
4 8 R/W bit weight 8°C
is reported in the remote value registers.
3 4 R/W bit weight 4°C
2 2 R/W bit weight 2°C
1 1 R/W bit weight 1°C
0 1/2 R/W bit weight 1/2°C (0.5°C)
