What Temperature Should An Attic Fan Be Set At. Attic Fan Temperature Setting Most attic fans operate with a thermostat that automatically turns the fan on and off based on a temperature the homeowner sets. When there isnt proper ventilation in your attic then hot air can become trapped between the insulation and the roof turning your attic into a large oven.
This helps push the hot air out of your attic. As was mentioned earlier an attics temperature should never exceed 130F and its really only in the summertime when this is even a possibility. Most manufacturers and contractors recommend a temperature setting between 100 and 110 degrees Fahrenheit.
In winter the humidistat operates the attic fan when the relative humidity exceeds a preset level usually 40 to 50.
