When Auto Mode is first enabled the air conditioner will run in COLD mode and target 73 degrees Fahrenheit for at least 3 minutes. If the room temperature is above 79 degrees the AC will remain set at 73 degrees. Once the temperature of the room is detected below 79 degrees the AC will continue to cool the room in Dry mode until the room temperature is around 68 degrees. The target temperature during this time will vary as the room cools. Once the temperature reaches 68 degrees or lower the compressor will turn off and will enter FAN mode. As the temperature rises the compressor will turn back on again to cool the room. While in Auto mode the fan will continuously run.
During this operation the fan speed can be changed however the temperature can not be manually changed.
