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: “――”

Compressor discharge temp.(Tp) 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.)
AD value of current
The display value is hex number.
EXV open angle for A indoor unit
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.)
