Function
Measured temperature data for the remote zone
Operation
Read-only
Power-up default value:
Command byte:
Each LSB represents one degree centigrade. The values are in a two’s complement binary format such that 0°C is reported
as 0000 0000b. See Temperature Data Format (above) for more details.
**TEMP will contain measured temperature data after the completion of one conversion.
