Compressor discharge temperature (TP)
The display value is between 30–129 ℃. If the temperature is lower than
30 ℃, the digital display shows “30.” If the temperature is higher than
99 ℃, the digital display shows single and double digits. For example, if
the digital display shows “0.5", the compressor discharge temperature is
105 ℃.
The display value is a hex number.
For example, the digital display tube shows “Cd”, it means AD value is
205.
EXV open angle for A indoor unit
Actual data/4.
If the value is higher than 99, the digital display shows single and double
digits.
For example, if the digital display shows “2.0", the EXV open angle is
120×4=480p.
