Hi,

1) in best case from the manufacturer.
2) it depends on the protocol and modulation scheme. There are some basic IR protocol standards. Thus you will find a lot of solutions in the internet. Just find out what you need than do an internet search.

***
If you want to go with trial and error, then get an universal IR remote control. Then try out which button which function means.

The problem is, you get no feedback to your universal controller.

Indeed I´m not sure whether your AC gives feedback at all, or the IR controller just "sends".
(my cheap AC communicates only one way. On the other hand mine has WiFi to be controlled via smart home)
