1 - Air Intake from Front Heater and A/C Unit in the Rear Air Distribution Housing
Note
The temperature of the air flowing from the front heater and A/C unit to the rear air distribution housing, is regulated by the Front A/C Display Control Head -E87- so that the air from the vents in the front area has an average temperature. The target temperature for the air from the vents in the front area is calculated via the setting for the left and right side on the Front A/C Display Control Head -E87- and the Rear A/C Display Control Head -E265- from the Front A/C Display Control Head -E87-. However, if a setting which no longer regulates the temperature (for example, "HI" for maximum heating or "LO" for maximum cooling) is present on the Front A/C Display Control Head -E87-, the temperature of the air from the vents in the front area is no longer regulated. If, for example, maximum heating "HI" is set on the Front A/C Display Control Head -E87- for one side and maximum cooling "LO" for the other side, the air for the vents in the front area is maximally heated.
