"If you have another DISH Network satellite receiver installed, you can use this remote in AUX mode to control it along with your new receiver. When you program the remote to control this other receiver, the remote will send out IR and UHF (not UHF Pro) signals to the receiver. You can program the remote to control any other DISH Network satellite receiver, except for following:
o TV2 on DISH 322, ViP222, ViP622 DVR, DISH Player-DVR 522, 625 and 942
o DishPlayer 7100/7200"
Program the AUX button to 3x, where x is the address of the receiver you want to control.
What I take this to mean is that the TV1 Tuner on the 622 is controlled using the same band of UHF frequencies as the older receivers, while a different band of frequencies (called 'UHF Pro') is used to control the TV2 Tuner. So if you set the TV1 address to different channels on your 2 622s, you should be able to do what you want.
Note that this only works with the TV2 remote (the one with the blue key). The green keyed remote is IR only (at least without some modification to the switches that I understand are hidden on the back of the key). You might want a blue keyed remote for each room with a TV.
My parents just upgraded their 811-->211 and 942-->622. As DishBacker suggested, I haven't been able to get the 811's 8.0 UHF Pro to work as a UHF remote for TV1 on the 622... I also have a 5.2 and 6.2, but the keys are incompatible...DishBacker said:Do note that this process does NOT work with a 6.0 or 8.0 remote... as I've tried with both. Seems only the 6.2 (and I guess the 6.3) can be programmed on the AUX button to control a second satellite receiver.
