I've been trying to figure this out, and I just can't seem to get past it. I am probably missing something simple because it is late at night. Basically, I'm using the OpenStudio.dll (C# bindings) at the AirLoopHVAC level, I have used OpenStudio's call to nightCycleControlType(), setting the value to "CycleOnAny". The AvailabilityManagerAssignmentList is updated with a n AvailabiltyManager:NightCycle and the NightCycle manager looks like this:

AvailabilityManager:NightCycle, Packaged Rooftop VAV with Reheat NightCycle Manager, !- Name Always On Discrete, !- Applicability Schedule Name Always On Discrete, !- Fan Schedule Name CycleOnAny, !- Control Type 1, !- Thermostat Tolerance {deltaC} 3600;

But, even though there is no zone demand, the fans still run and my main AirLoopHVAC node still has flow. What am I missing or not setting? I thought all I had to do was set this up at the AvailabilityManager level, and everything below it would be overriddedn. Is it something weird, like the applicability schedule name and fan schedule name can't be the same?
