I have 4 Omnistat 2 thermostats connected to my OmnoPro II. When I push the scroll wheel on an Omnistat 2 to display the Main Menu, the only options I get are Setup and Run Time Graph. I don't have a Program option. I used to because I did program them all once. They are all set to "Energy Level: low". Does this have anything to do with it? If so, how do I get them out of this mode? If it's not that, any other ideas?
