Ideal attic temperatures shouldn t be more than 10 to 20 degrees hotter than outside temperatures. When the temperature within the attic reaches a set point the fan will turn on and start venting the heated air cooling the attic space. The reason is that attic fans depressurize attics and can rob air conditioned air from the main body of the house greatly decreasing efficiency. In particularly hot climates set the temperature higher to keep the fan from running for extended periods of time.

Attic ventilators generally turn on between 90 and 110 degrees fahrenheit. In general most homeowners should set their attic fan temperature to in between 90 and 110 degrees fahrenheit.
