What does the car button zone mean?

[HeidiFitz]

The zone on a car refers to the air conditioning temperature zoning control, which means the left and right sides of the car air conditioning can be set to different temperatures and air volumes. More details about it are as follows: 1. The function of zone air conditioning temperature zoning control is: designed for passengers with different temperature needs, allowing different air conditioning temperatures and air volumes to be set for different areas inside the car. Temperature zoning control is divided into two-zone and multi-zone. Two-zone refers to the temperature control on the driver and front passenger sides. Multi-zone adds temperature control for rear passengers. 2. The principle of zone air conditioning temperature zoning control: The principle is to add air conditioning dampers, dividing the air ducts into finer and more sections, which are then sent to different pipelines after passing through several mixing dampers. The mixing dampers are controlled by multiple independent controllers.
