The display value is between 30~120 degree. If the temp. is lower
than 30 degree, the digital display tube will show "30".If the temp.
is higher than 99 degree, the digital display tube will show single
digit and tens digit. For example, the digital display tube show
"0.5",it means the compressor discharge temp. is 105 degree.)
The display value is hex number.
Actual data/4.
If the value is higher than 99, the digital display tube will show
single digit and tens digit.
For example ,the digital display tube show "2.0",it means the EXV
open angle is 120×4=480p.)

example, the
digital display
tube show
2A,then Bit5=1,
Bit3=1, Bit1=1.
It means
