Different models of Aqualink RS8 for dual-equipment and combo-equipment systems?

If you have seen my earlier post regarding problems controlling my separate pool and spa heaters after upgrading my old Aqualink RS8 to the latest version for iAqualink, you know that it was a real head-scratcher. Now it appears that the problem may be simpler than anyone thought, but I need confirmation. In the Help screen of iAqualink, I see that my new Aqualink board has Rev T.2 firmware and the model shows as "RS-8 Combo." The CPU p/n shows as B0029221.

Is there a different model of the RS-8 board for dual-equipment systems (separate heaters and pumps for the pool and the spa)??? I can't find anything about that online, but the behavior I'm experiencing is consistent with the system not recognizing that I have dual equipment, so I'm thinking that must be the case. If so, can someone point me to the proper part number (and if you are in the market for a slightly used RS8 board for a combo system, ...).
 
The catalog is helpful, thanks. It looks like the iQ20-RS upgrade kit that I used is only available with the board that supports single-body and combo systems only. I think I needed the RS2-6 board for dual-equipment systems. Can anybody confirm that I am right on this? Will iAqualink even work with the RS2-6 setup? If so, I wonder why that isn't that an option when ordering the iQ20-RS. Assuming it works with iAqualink, I'm not sure whether I need to order just the RS2-6 CPU board or the upgrade kit that has the board along with the keypad and bezel (i.e., does the RS2-6 have a different keypad attached to it from the RS8)?
