[EnergyPlus_Support] Re: Disable a DX coil below "xx" temp



I'm going out on a limb here, but I think I read somewhere that an EMS actuator exits which can reach into the dx object inside a unitary system...but I can't remember anything else. It may be worth running a simple EMS with the "verbose" commands and looking at the .edd file if there are any usefull actuators available. 

If I remember, I'll check it for you tomorrow.
