    Aaon VCM controllers: override capabilities?

    I've got a campus with lots of Aaon units, mostly integrated lon. They're like teenagers. I tell them to go unoccupied, they don't listen. Is there a writable point that will reliably shut these things down and start them up, or am I at the mercy of this %$*& lousy protocol?

    I had a job where I had to shut down an AAON unit running on WattMaster to change return filters. I tried to do it with Prism but sometimes they would not shutdown or restart. I ended up just killing the power. If the units are being controlled with WattMaster or Envision then the best way would be open the emergency shutdown input with another controller. If this is already being used for the FA then it might not be legal.
