Dual Zone Setting

Adjust the passenger control head in order to select the dual zone mode. The programmer energizes the driver and the passenger air mix valves independently. The passenger may operate the passenger temperature control knob in order to request a warmer or a cooler temperature on the passenger side of the vehicle. The programmer energizes the passenger air mix valve actuator in order to increase or decrease the passenger side discharge temperature, if the set temperature is not the maximum hot or the maximum cold setting.
