In particularly hot climates set the temperature higher to keep the fan from running for extended periods of time.
Attic fan turn off temperature.
Cooler outdoor air enters through open windows lowering the indoor temperature.
I recently bought a house that has an attic fan on a thermostat that seems to run whenever the outside temperature gets above about 70.
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.
Likewise adjustable thermostats will shut the fan off.
Most attic fans operate with a thermostat that automatically turns the fan on and off based on a temperature the homeowner sets.
The attic has about 2 3 of blown in cellulose is pitched i don t know the pitch but it s about average for a typical suburban house and has a gable vent on each end l shaped house.
Some can have manual switches while others use a thermostat to turn them on and off automatically.
Also you place it on the roof top or gable mounted.
Open your windows before you turn on the fan.
Attic fans come with different models.
What temperature should attic fan be set at.
Most manufacturers and contractors recommend a temperature setting between 100 and 110 degrees fahrenheit.
In the late evening or early morning the fan is turned on to exhaust hot air from the house.
A whole house fan is usually installed on the attic floor near the center of your house.
The house was constructed in 1958 and is 2x6 wood frame on 16 centers.
