Automatic Control

For most efficient operation you should set the system temperature and press AUTO. The system will select the best fan speed and airflow settings to keep you comfortable. The air conditioning compressor will run if the outside temperature is above 38°F (3.3°C). You may notice a delay of three to four minutes before the fan comes on.
