Passenger Control (Dual Zone)

The passenger temperature control consists of a rotary potentiometer with seven positions. The control head communicates directly with the A/C programmer through varying an analog voltage.

Turning the knob to the right or left causes the A/C system to begin operating in the dual zone mode. The passenger can raise or lower passenger side discharge air temperature by turning the knob in the appropriate direction.

Discharge air temperatures could be different from side to side when not in dual zone mode, due to greater sun load on one side of the vehicle.
