I am involved with a CCN system and one of the AC systems connected to it is a six zone VAV. The AHU fan for the VAV system is always ON. I removed all schedules to be sure a schedule wasn't causing it to run. When I look at the status page, it is not forced on, although I can't change the run status to AUTO either. When I attempt to do this I get a "Force/Auto error: insufficient priority" . Any ideas?
