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.)
