dougrainer, thanks again. Zone 2 is listed, it just didn't show any functions. There has been no work done on the A/Cs. I wasn't able to get up on top but did go ahead and go through the reset procedures you provided. I did get the FF indicator. Once completed it now shows only "AGS Mode" and I can toggle on or off. I believe this to be part of the Automatic Generator Start feature which I don't need at this time. It doesn't permit me any other function options on Zone 2 however, just the AGS Mode. Zones 1 and 3 are still working fine.
