It's inevitable to eventually notice in the trends for your RTU or AHU that 75F tracks conditioning mode and operation mode. They sound and look like the same thing!
Conditioning Mode - is the user intent, or user selected setting. Options include Off, Auto, Cool Only, or Heat Only.
Operation Mode - The mode that the system is actually operating in. If Auto is selected as the conditioning mode, then the operation mode tells you whether the system is operating off the heating loop output or the cooling loop output.
