How to I find a list of IR codes for my remote?

Other Hardware LEDs and Multiplexing
1

I need to write a climate control algorithm. My issue with the air conditioner is if I set it to 74 degree then turn it on/off, it stay 74 but if I cut power to it, then it reset with the air compressor turned off and the thermostat set to 66 but no air compressor.

So, I have to go through the IR and the remote so I can get some control over the compressor and temp

I was able to dump the codes from a receiver.

protocol=NEC1 device=12 subdevice=34 obc=56 hex0=227

and I can turn the machine on without any issues after cloning a code or two.

My issue is this. The algorithm I am trying to write would be so much better if I could send a temperature like 73 degree and not up/down. I have to account for a brownout.

There are many hints on this very exotic (looks 3rd party to the manufacturer of the ac) remote control that it has more codes available than I whats on the face of the remote.

How do I use that dump to track down the rest of the codes? The remote gives no hints.

Ariconditionaer IR codes are a complex set and incompatible with 'normal' appliance IR codes. Searching for your brand of A/C and keywords like 'remote control codes' usually gets you somewhere. What have you tried?

The guys at AnalysIR FREE Download have software tool that you can use to analyse IR streams and they support a number of A/C formats. Not sure what the free version has as I paid up for mine some time ago (really cheap and worth it even for just one project).
