I have a 722 in single mode for my down stairs TV. Bought a new 32 LCD Sammy to replace an older TV in the bedroom that was hooked up to a 522 in dual mode with my sons TV. So I called Dish to see if I could get another 722 to replace the 522, and was told not at this time, but I could get a 622. I said ok. The installer showed up with a 722K. Sweet. No OTA module, but one is now on the way. When he took the 522 he took the remotes as well. I am thinking about switching the 722 and the 722K locations. I use a harmony 880 for my living room set up. If I do this, can I use the 722K remotes on the 722 (duel mode/upstairs), and control the 722K(single mode/living room) with the Harmony?
