Controls and Features The display window and the function selector buttons indicate how the system is operating. The display window shows the selected temperature and displays AUTO if you are operating in the AUTOMATIC mode. If you override the automatic mode by selecting any of the function selector buttons, AUTO no longer appears in the display window and the appropriate function selector button(s) illuminate. The display window also indicates manual (thumbwheel) control of the fan speed when a H is shown. Automatic Operation Push the AUTOMATIC button and select the desired temperature. The selected temperature and AUTO appear in the display window. The ATC heats or cools to achieve the set temperature. It is important to note that if the ATC engages your vehicle's air-conditioning, it will do so automatically without illuminating the A/C button. When in AUTOMATIC and weather conditions require heat, air is sent to the floor. However, a feature is included in the ATC to prevent blowing cold air to the floor if the engine coolant is not warm enough to provide heating. Within three or four minutes (of determining the engine coolant is warm enough), the fan speed gradually increases and airflow changes to the floor. If specific conditions exist (such as window fogging), the five override buttons allow specific airflow selection. The thumbwheel allows you to adjust the fan speed to suit your needs. Temperature Selection The d TEMP c button on the left side of the control panel is for temperature selection. The d side lowers the set temperature, and the c side raises the set temperature. Press and hold either side of the button to rapidly change the temperature setting in one degree increments to either 65˚F 69
