RE: [EnergyPlus_Support] Set point control on AHU from zonal feedback



It is pretty common to have systems that monitor return air to the
system when making operating decisions (heat and humidity), so perhaps
being able to use various parts of the mechanical system for set points
would be a useful program extension.

There's no way to do this right now. I'm sitting in a building that has 
a similar
system. Seems like we need a new set point manager.
