Reread posts 5, 16, and 17 of this thread. The codes he got to work are the ones from post 5.

I believe a TSU3500 doesn't need the long form of these codes. It should work equally well with the "900A" form (see post 2 of this thread).

I assume you've tried some of those codes and failed. Without more info I can't tell what went wrong.

When testing a discrete code, you should program it as the only action on a button and test it with an long press of that button.

I understand it makes no sense to use a discrete that way. You want to use it in a macro. But that introduces lots of timing and other complicating factors. First find out whether it is the right discrete code. Only if it passes that, try to use it in a macro and tweak whatever timing must be tweaked to get it to work.
