There was a time when automotive air conditioning was an option, and dashboard heat had two settings: "not very hot" and "melt your floor mats." Maintaining a comfortable cabin climate required a choreography of heat on, heat off, and opening the windows ("just a crack"). Today's set it-and-forget-it world mandates a one-touch solution to cabin creature comfort. Ford's Electronic Automatic Temperature Control (EATC) uses sensors, modules (computers), and electric motors to maintain a desired temperature inside the passenger compartment. The system controls airflow, air temperature, and air volume to sustain the comfort level selected by the vehicle's occupants. Dual Automatic Temperature Control (DATC) allows the driver and the passenger to enjoy their own individual temperature zones. This article will discuss the inputs, the outputs, the components, and the strategies that drive Ford EATC. We'll spend very little time discussing base climate control. I'm sure you understand how an A/C compressor and a heater core operate. |
