During the summer, an attic can be 40-50° hotter than the outside temperature, which in turn heats up the house very quickly. With an attic fan, you can cool the attic to the same temperature as it is outside, greatly reducing the house from heating as quickly.
With the Smart Roof Mount Attic Fan, gone are the days of having to adjust the thermostat for your attic fan. When the fan detects temperature over 80°, or humidity over 60%, the Smart Attic Fan comes on at the lowest speed. As the attic starts to heat up, the Smart Attic Fan automatically adjusts it's speed.
This attic fan is able to keep the attic cooler since it ramps up the speed of the motor in accordance with the temperature in the attic rather than a standard single speed attic fan that would come on at a higher temperature.
