Air Temperature Control

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2018 Land Rover Range Rover, 2017 Land Rover Range Rover, 2016 Land Rover Range Rover, 2015 Land Rover Range Rover, and 2014 Land Rover Range Rover. However, it is still accessible from the selected car via links, so may be relevant.

The Automatic Temperature Control Module (ATCM) calculates the temperature blend motor positions required to achieve the selected temperature and compares it against the current position. If there is any difference, the ATCM signals the motors to adopt the new position.

Air temperature is controlled automatically unless maximum heating (HI) or maximum cooling (LO) is selected. When maximum heating or cooling is selected, a comfort algorithm in the ATCM adopts an appropriate strategy for air distribution, blower speed, and air source.

Temperature control in one zone can be compromised by another zone being set to a high level of heating or cooling. True maximum heating or cooling (displayed as HI or LO on the Touch Screen (TS) and switches) can only be selected for the driver zone. If HI or LO is selected for the driver zone, the temperature for the other zones is automatically set to match the driver zone.

If A/C is selected off in the automatic mode, no cooling of the inlet air will take place. The minimum output air temperature from the system will be ambient air temperature plus any heat pick up in the air inlet path.

If the Sync soft key on the TS Front climate menu is pressed, the ATCM synchronizes the temperature of the other zones with the driver zone temperature.
