M Law said:Yes, you can. I've had mine set-up to control 3 - 6000, 811, and a 522 since the 522 and 811 were installed a few days ago. No problems so far, other than I have not found the right way to control the 2nd tune in the 522, which really is like a 4th receiver. Harmony support will straighten me out whenever I get the chance to call the help desk.
