Attic fan thermostat setting.

I think the normal average setting is 110 or higher if you are in a hot climate. If your attic soars above 100 degrees and reaches the 150 mark its time to consult. When it comes to adjusting the thermostat of your attic s fan it s best to adjust it to approximately 90 to 95 degrees. When that temperature is reached or exceeded the thermostat ensures that the attic fan is switched on.

Of course some environments are much hotter than others so this will be the perfect time to measure out how warm your attic will get during the most heated of seasons. This temperature can be anywhere between 80 to 120 degree fahrenheit. When the temperature drops below that set temperature it is again switched off. Most attic fans operate with a thermostat that automatically turns the fan on and off based on a temperature the homeowner sets.

In particularly hot climates set the temperature higher to keep the fan from running for extended periods of time. Most manufacturers and contractors recommend a temperature setting between 100 and 110 degrees fahrenheit. Ideal attic temperatures shouldn t be more than 10 to 20 degrees hotter than outside temperatures. But if your attic rarely breaks 100 then i guess that s the temp to set it at.

My attic virginia breaks 100 probably every day during the summer. What temperature should attic fan be set at.
