The present invention is a process of controlling a hybrid central air conditioning system that incorporates multiple air treatment devices operated by a process controller reacting to an input of either a comfort or an energy saving program and which uses temperature and humidity sensors that matches specific air treatment machines to varying air treatment needs, such as humidity control to maximize air conditioning performance while minimizing energy use. A timed test cycle is used to make corrections to the selected program based on a timed reading of the temperature and humidity sensors.
