Choose the Fan Setting (Auto or On)

Fan 

Auto

 is the most commonly selected setting and runs the 

fan only when the heating or cooling system is on. 

To prevent compressor and/or property damage, if the 
outdoor temperature is below 50°F, DO NOT operate 
the cooling system.

CAUTION

!

Fan 

On

 selection runs the fan continuously for increased air 

circulation or to allow additional air cleaning.
Tip: Running the fan more frequently will increase your 

energy consumption. Most systems use a 1/2 or 1/3 HP 
electric motor to power the fan.
