Yes the complete state is sent each time.
You should learn several times the code. Each time you just change one thing, let say say the temp.
Each time you youd analyse the difference.
I succed in it for my AC (hitachi) the following field are coded :
- button
- state on/off
- temperature
- timer 1, 2, 3
- air speed
- header
- footer
- CRC
