Re: [EnergyPlus_Support] Problem with EMS and controlling AirLoopHVAC System Availability
Why don't you try controlling the fan object in the air loop instead of
the AirLoopHVAC object itself (which could be many objects other than
the fan). If your intent is to control all objects in the air loop, then
control those as well.
