Actual data*HP*10
If capacity demand code is higher than 99, the digital display
tube will show single digit and tens digit. (For example, the
digital display tube show "5.0",it means the capacity demand
is 15. the digital display tube show "60",it means the
capacity demand is 6.0)
If the temp. is lower than 0 degree, the digital display tube
will show "0".If the temp. is higher than 70 degree, the digital
display tube will show "70".
If the temp. is lower than -9 degree, the digital display tube
will show "-9".If the temp. is higher than 70 degree, the
digital display tube will show "70". If the indoor unit is not
connected, the digital display tube will show: "――"
The display value is between 13~129 degree. If the temp. is
lower than 13 degree, the digital display tube will show
"13".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 digital display tube show
"1.6",it means the compressor discharge temp. is 116
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.)
