What does the 3zone car button mean?

[DeEmmett]

3zone refers to three-zone control. When the switch light is on, it means the rear air conditioning is controlled by the rear control panel. When the switch light is off, it means all air conditioning is uniformly controlled. Below is relevant information about the zoning feature: 1. Zoning function: The zoning function is not particularly high-tech; it simply adds air conditioning dampers to divide the air ducts more finely. There is a main mixing damper, and then the ducts branch out to each zone, with each zone having an independent controller. 2. Purpose of zoning: It provides a more comfortable environment for drivers and passengers, as some children or elderly and weak individuals may not tolerate strong cold air or low temperatures. The purpose of zoning is to accommodate passengers in each area, allowing everyone to freely control the air conditioning speed and temperature within their own space.
