Temperature Control

Individual temperature control is provided by the temperature control damper motors on the driver's side (16) and passenger side (17) in response to signals from the control module (1). The control module computes the damper limit positions on the basis of the following information:
- Temperature Control Settings (22, 23).
- Duct Temperature. The air temperature downstream of the control dampers, as indicated by the duct temperature sensors (3, 4).
- Interior Temperature On The Driver (5) And Passenger Sides (6). The difference between the desired and actual interior temperature on each side has a direct effect on damper positions.
- Solar Radiation (2). The temperature control dampers are set for lower heat in sunshine.
- Engine Temperature (8, 9) And Outside Temperature (7). If the engine is cold and the outside temperature low, the dampers are set for more heat to reach the desired temperature faster.
Setting the temperature controls to max. or min. sets the dampers to the limit positions for max. heat and max. cooling respectively. If the driver's side temperature is set to:
- Max. Cooling. The highest fan speed is selected and the air distribution is the same as in the ventilation setting.
- Max. Heating. The highest fan speed is selected and the air distribution is the same as in the floor/defroster setting.
