I know carrier had an issue a while ago that cause the bypass controller and air source controller to get locked in a conversation that wouldn't allow anything to happen, like going occupied. That was "fixed" through a software upgrade to the bypass. I'm wondering if this is still an issue as I had a unit similarly stuck this week and as soon as I addressed the bypass outside the scanning range of that linkage coordinator, the unit went occupied. Any thing I haven't heard about yet?
