What does the AUTO position on temperature controls ensure?

The AUTO position on temperature controls is designed to maintain a consistent temperature range within the cabin environment. When set to AUTO, the system automatically adjusts heating or cooling to ensure that the temperature remains stable, providing a comfortable atmosphere for passengers and crew throughout the flight. This automatic regulation helps respond to varying external conditions, such as changes in altitude or outside temperature, without requiring manual intervention.

In contrast, other options do not align with the primary function of the AUTO position. The setting does not simply set a maximum temperature, nor does it deactivate the controls or limit the system to manual overrides. Instead, it actively works to achieve and maintain the desired temperature within the specified range, ensuring passenger comfort and efficient climate management onboard the aircraft.
