When this bit is 0, the local offset is added to the Local Temperature Reading. When
this bit is set to 1, the local offset is subtracted from the Local Temperature Reading.
These four bits are used to add an offset to the Local Temperature Reading. These
bits allow an offset value of up to ±15°C to be added to or subtracted from the
temperature reading.
When this bit is 0, the remote offset is added to the Remote 1 Temperature Reading.
When this bit is set to 1, the remote offset is subtracted from the Remote 1
Temperature Reading.
Unused. Read back 0.
These four bits are used to add an offset to the Remote 1 Temperature Reading.
These bits allow an offset value of up to ±15°C to be added to or subtracted from the
temperature reading, depending on the sign bit.
When this bit is 0, the remote offset is added to the Remote 2 Temperature Reading.
When this bit is set to 1, the remote offset is subtracted from the Remote 2
Temperature Reading.
Unused. Read back 0.
These four bits are used to add an offset to the Remote 2 Temperature Reading.
These bits allow an offset value of up to ±15°C to be added to or subtracted from the
temperature reading, depending on the sign bit.
