Re: [EnergyPlus_Support] Constant volume, constant temperature

First report the node set point temperature so you can be sure it is 
accurate. Second, if you are using the AirloopHVAC:UnitaryHeatCool 
object (which is controlled by zone load), change to the 
AirloopHVAC:CoolOnly (which can be controlled with a set point manager).
