Datc System Auto Temperature Balance - Ford 2002 Thunderbird Owner's Manual

Climate Controls
When in AUTO and weather conditions require heat, the DATC directs
the majority of the airflow to the floor area. The system will allow some
airflow out of the defroster, demister outlets and outer instrument panel
registers in order to reduce window fogging. Additionally, if the engine is
not warm enough to provide heat, the fan will operate at a low speed
and the airflow will be directed to the windshield or to the floor. In
approximately 3 ⁄ minutes or less, the fan speed will start to increase
1
2
and the airflow location will change to the floor area.
When in AUTO mode, the DATC system automatically controls the air
conditioning operation, the fan speed, the airflow direction and
determines whether outside or recirculated air is required. Manual
control of the A/C, air recirculation and fan speed are available in auto
mode.
If unusual conditions exist (i.e. window fogging), the manual override
controls allow you to select airflow locations as necessary. To return to
full automatic control, press the AUTO control.

The AUTO control may be used to toggle between single zone control
and dual zone control.
When in dual zone control (both driver and passenger set temperatures
are displayed), press and hold the auto control for approximately two
seconds to equalize the passenger set temperature with the driver set
temperature. Only the driver set temperature will be displayed. This
feature is useful when the driver is alone in the vehicle.
