Thank you, i will try this tonight at home.

Something I forget to say, yesterday I tried the ON, OFF code of the A1 system. I pasted the code into a button with the Pronto Editor. When i now pressed the "Test IR" button, the code worked and the BeamIt switched off. But when i downloaded the hole thing to my Remote, and pressed the button on the remote, then the code didn't work. Can someone explain this?
