RE: [EnergyPlus_Support] Problem with EMS and controlling AirLoopHVAC System Availability

I am not seeing any problems in these inputs. Check the error file, maybe the AirLoopHVAC is not loading because of other problems.

As far as the EDD content, check that you have the Output:EnergyManagementSystem object set to verbose for Actuator Availability Dictionary Reporting.

Subject: [EnergyPlus_Support] Problem with EMS and controlling AirLoopHVAC System Availability

Hello,

I'm trying to use EMS to control a fan system based on outdoor air temperature and wind speed. The control logic is simple enough, but I keep getting an error when trying to run the simulation.
"Invalid Actuated Component Type =AIRLOOPHVAC"

I'm not sure why, but AirLoopHvac is not recognised as a valid actuator component type, and it does not appear in the .EDD file when I run a simulation without that particular control included.

Can anyone help me understand why I cannot use AirLoopHVAC Availability as an actuator here, and why it is not appearing in the .EDD file either??

I've included what is hopefully enough of the relevant code. The entire input file is too big to copy here.
