Good evening, I have successfully decoded the remote control of my Mitsubisho air conditioner with the fantastic AnalysIR.
Now I have some doubts about how to manage the various saved codes.
I can switch on, switch off and switch between software modes.
Now I can not understand if each mode has its own
fan speed
temperature
addressing the flow of air
That is, if I set the cooling and increase the fan speed to 4, the fan speed control will be different from fan speed to 4 in heating?

That is, if I send a command already contains fan speed, air addressing and temperature?

At the moment I created a python script which receives a 4-digit value (1234)
Thousands are the mode
The hundreds are the fan speed
The tens are the orientation of the lamellae
The units are the degrees

Practically:
1000 = heating mode
2000 = cooling mode
.....
2100 = cooling mode with fan at 1
2400 = cooling mode with 4 fan
.....
2450 = cooling mode with automatic lamella orientation
.....
2456 = cooling mode with automatic slat orientation 16 degrees

I thought so and for what I did it works but I understand that it is not the right method.

Can you help me to understand better?

Thanks, Alberto

AC remotes typically send the complete config/settings in each signal.

There will be fixed bit-fields for each of the settings and usually a checksum field to verify the integrity of the signal.

The other thing to look at is the bit order. Usually LSB8(Power Tools menu) is best, but not always.

AnalsyIR has a reverse engineeringtool & checksum calculator to help with that.

Maybe looking at the videos will help. There are also several blog posts about reverse engineering AC units on our blog.
