The display value is between 30~129 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.
For example ,the digital display tube show "Cd", it means AD value is
205.
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.)
