These aren't that technical.....the dash control in the new models contains the whole brains to how it works.....ATC is only controlled temp, doors and fan speed....
ATC systems contain what we’ll refer to as three major component groups. These are:
The Controller – The “brains” of the system;
The Sensors – Supply the controller with pertinent input data;
The Controlled or Output Devices – Vacuum solenoids, electric motors, etc. that eventually turn electrical signals into mechanical motion.
Of course, an ATC system contains many other components, such as the refrigeration system, the blower motor, ductwork, wiring, etc. These components essentially work the same way in an ATC system that they do in a manual temperature control (MTC) system.
As noted, the ATC controller is the “brains” of the system. It processes the data it receives from its sensors and issues output commands to the various devices it controls. Really, it has only one job: to do whatever it takes to keep the interior of the vehicle at a stable set temperature as selected by the vehicle occupants.
ATC controllers are essentially microprocessor devices, mini-computers very similar to the type that control electronic fuel injection systems. They gather input data from sensors, make decisions based on the sensor data, then issue appropriate commands to controlled devices, with the end result usually some type of mechanical motion. Examples of this could be a heater control valve opening or closing, a vacuum control solenoid passing vacuum through to a vacuum actuator, an electric motor moving a temperature blend door, etc. The result of a controller command may not always be motion, however. Sometimes, controllers issue electrical commands to other components, such as blower motor power modules.
