4. SYSTEM OPERATING INSTRUCTIONS
4.1 QuietCool Smart Attic Fan (AFR SMT-2.0)
QuietCool Attic Fans work almost everywhere, anytime. During the summer, an attic can be 40-50 degrees hotter
than the outside temperature, which in turn heats up the house much faster. 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 QuietCool Smart Attic Fan, gone are the days of having to adjust the thermostat for your attic fan.
Featuring a built-in thermostat and humidistat, the self-adjusting, 10-speed ECM motor is always reading the
temperature and humidity in the attic.
When the fan detects temperature over 80 degrees, 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.

The QuietCool Smart Attic Fan will help your attic stay cooler than with a traditional single-speed attic fan, and
will help save you energy by running the fan at a lower speed (thus a lower wattage) when the attic is not
as hot.
4.4 QuietCool Roof Mount Fans (RM ES-1100 and RM ES-2200)
The QuietCool (RM) Roof Mount Fans are the most versatile fans that we offer. They can be used as an attic fan,
a whole house fan with a duct, or a whole house fan with multiple inlet vents. QuietCool Roof Mount Fans also
work where a conventional QuietCool Whole House Fan will not. Roof Mount fans work with homes that have a
sealed attic, manufactured homes with no attic, homes with cathedral ceilings, and even industrial buildings
such as warehouses.
If you installed your Roof Mount as a whole house fan, run the fan when it is cooler outside than it is inside your
home. Be sure to crack open a few select windows in your home and let the Roof Mount fan do the rest.
If you installed your Roof Mount as an attic fan, set your thermostat and let it run! When installed as an attic
fan, it is effective almost everywhere, almost anytime.
