I have aircondition: "Mitsubishi km09a" and I tried to lear codes form it in almost all modes (normal, raw...) and it doesn't work. I have IRTrans USB with COD-RCV universal receiver. Could you help me please what to do? Thank you verry much!

Please upload the .rem file that was created during learning of the codes. Maybe we can see what went wrong.
Normal learning mode should be ok with A/C codes.

regards,
Eric

A few further suggestions:

- A/Cs do not have an IR Code for Temp Up or Temp Down. Instead they send the complete status of the device each time you press a button. That means nothing will happen if you send the same code many times in a row.
- Never learn A/C Codes using the RAW Mode. Those codes are to long for the RAW Mode
- When the codes are not working please try the Code Calibration option when learning the codes
- You can try a longer IR Timeout when learning (e.g. 250ms)

If you still have problems please send us the .rem file - but no RAW file, that does not help.

Thank you verr much for your answers! I know that aircondition remotes send the complete status of the device each time you press a button. I will try to learn codes in "normal mode with timing" with all those settings that you suggested me and then if it still doesn't work I will put the rem file here.

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
