In Auto Mode (SMART) the system will automatically switch to Cooling, Heating, Dry or Fan Only modes based on the current
room temperature. Air flow direction can be adjusted in any mode.
The auto set point is determined by the user.
When the room temperature is 79°F or above, Cooling mode will activate.
When the room temperature is between 73°F and 79°F, Dry mode will activate. Fan Speed will drop to LOW after 3 minutes.
When the room temperature is between 70°F and 73°F, Fan only mode will activate. Fan Speed is automatically set to LOW,
but can be adjusted when between these room temperatures.
When the room temperature is below 70°F, Heating mode will activate. The room temperature is set to 72°F.
