Function
measured temperature data for the remote
zone*
read only
Operation
TEMP1 Power-Up Value: 0000 0000_b = 00_h (0°C)^†
TEMP1 Command Byte Value: 0001 0000_b = 10_h
* Each LSB represents one degree Centigrade. The values are
in a two's complement format such that 0°C is reported as
0000 0000_b. See "Temperature Data Format" for more details.
† _{TEMP1 will contain measured temperature data for the}
selected zone after the completion of one conversion.
