I am not aware of any alternate power codes.

What control system are you using? Details about your control system and particular configuration may help.

I would make sure your copy-n-paste methods did not truncate the code somehow and that you do not have any issues with your settings, RF configuration, etc...

If you can learn the power and input codes from your native remote and send them to me, I would be happy to take a look at them and see if I can determine the particulars.
