ATC - AUTOMATED TOUCH CONTROL
The ATC system consists of several products:
How ATC Works
In its Auto mode, the touchscreen and CPU enclosure work together with the temperature and pressure sensors to automatically regulate intake and exhaust airflow. By default, Auto mode starts with main engine ignition. While the engines are running, the system uses data from the temperature and pressure sensors to maintain optimal temperature and pressure. When the main engine shuts off, the system transitions into "cooldown", only turning the fans on when the engine room temperature gets too warm. Auto mode is the most efficient way to run the ATC system.
If you wish to control the system manually, ATC also has a Manual mode. In this mode you can use the touchscreen to change fan speed and direction with just a touch.
