www.QuietCoolSystems.com/support
1-888-QUIETCOOL8
SETTING UP YOUR FAN
Once your attic fan has power, open up the QuietCool
Smart Control app. You will be taken to the Home
Page. You should see your attic fan show up in the list
of available fans.
A message indicates that setup is required. Press and
hold the Pair button on the Hub until the LED indicator
begins to blink.
NOTE: You will need to initiate this Pairing process
on each device you want to use to control your attic
fan. Once the initial device is paired, you can use the
“Enter Pair Mode” function from the app described
on page 11. This will prevent you from having to
access the Hub physically in the attic in order to
perform pairing operations.
Tap on the fan to start the setup process. Once you
tap on the fan, you will be taken to the Fan Setup
page.
On this page, you will be able to change the following
settings:
• Fan Name
• Fan Model
• Serial Number
The Speeds Available section will tell you if you have
connected the fan and set your dip switch properly.
Make sure that this number matches the specication
of the fan you purchased.
In this example, we are setting up an AFG SMT PRO-
2.0 which is a 2-speed fan.
The QuietCool Smart Attic Fan Control has an
innovative Smart mode that allows the fan to adjust
the speed based on the temperature and humidity
conditions in your attic.
Tap Climate Settings & Presets to adjust these
settings.
QUIETCOOLSYSTEMS.COM 9
CLIMATE SETTINGS & PRESETS
Within Smart Mode there are two standard presets,
Summer and Winter. You can modify these presets and
add your own custom presets to allow quick setting
changes on the y.
TEMPERATURE
• The settings you choose in this section will change
what temperature the fan will come on at each set
speed.
• Tap on any speed to adjust the temperature for
each speed.
HUMIDITY
• Turn Fan Off: This is the humidity percentage that
will cause the fan to turn off. For example, the
factory setting is set at 90%, meaning the fan will
turn off if the humidity in the attic is 90% or higher.
Tap this setting if you would like to adjust the
percentage. If you do not want this feature, you can
select OFF at the top of the list.
• Turn Fan On: This is the humidity percentage
that will cause the fan to turn on, regardless if the
temperature settings are not met. For example,
the factory setting is set at 70%, meaning the fan
will turn on if the humidity in the attic is higher than
70%, even if the temperature in the attic is below
the temperature settings in the app. If you do not
want this feature, you can select OFF at the top of
the list.
• Desired Speed: This is the speed the fan will use if
the humidity causes the fan to turn on.
These settings will be saved into the memory of
the Hub meaning all settings will sync between any
additional devices you pair to the Hub.
Click Done to complete Fan Setup. You can always
access these settings again from the Settings option
on the Fan Control Page.
1-888-QUIETCOOL10
SMART MODE
Smart Mode will automatically change the speed
based on the attic temperature and humidity.
To activate Smart Mode, simply tap Activate Smart
Mode.
In Smart Mode, the rst paramater that is checked
is the Turn Fan Off humidity level. Regardless of the
temperature in the attic, if the Humidity level in the
attic is above the Turn Fan Off humidity setting, the
fan will not turn on, or if it is already running, the fan
will shut off.
If the humidity in the attic is below the Turn Fan
Off humidity setting, the second paramater that is
checked is the Attic Temperature. If the temperature
inside the attic is within the set parameters in the
app, the fan will turn on at the appropriate speed.
If the temperature in the attic is below any of the
temperature paramaters, the last paramater that
is checked is the Turn Fan On humidity level. If the
humidity level in the attic is above the Turn Fan
On humidity paramater but below the Turn Fan
Off humidity paramater, the fan will turn on at the
Desired Speed.
TIMER MODE
Timer Mode is a simple way to turn your attic fan
on for a set amount of time at a set speed.
To activate Timer Mode, simply tap Activate
Timer Mode. Once activated, you can select your
speed by tapping Set Speed. You can also select
your runtime by tapping Set Time.
When Timer Mode is active, you will see your
remaining time left on the timer at the top of the
screen.
QUIETCOOLSYSTEMS.COM 11
PAIR MODE
Pair Mode is a feature that was designed to
prevent users from having to get into the attic to
access the physical Hub in order to pair additional
devices.
NOTE: In order to use this feature, you must
have one device that is already paired to the
Fan Hub. If you do not have any devices that
are currently paired to the Fan Hub, you will
have to press the physical Pair button.

will now be taken to the Fan Setup page and you
are now paired.
FIRMWARE UPDATE
Your attic fan includes a Firmware Update feature in
order for us to update your Fan Hub to include bug
xes and additional features in the future.
We recommend checking for a new rmware update
a few times per year.

phone is on cellular so if you are not currently
connected to a Wi-Fi network on your phone, tap
Choose Wi-Fi. This will take you to your phone
settings. Connect to your home Wi-Fi network and go
back to the Smart Control app.
Once back in the app, your Wi-Fi network name will
be pre-lled. Type in your Wi-Fi password and tap
Save. The rmware update will now begin.
Once completed, an alert will popup indicating that

3.3 Frequently Asked Questions
What protocal does this control use?
This control operates over Bluetooth to connect to your phone.
Will my neighbor be able to control my fan if they have the same set up as me?
No. In order to connect to your Smart Attic Fan Control Hub, you must rst pair your device
by using the Pair button on the Hub.
What is the range?
The range restriction between your phone and the attic fan is 50 ft.
Why are all my lights solid on the hub and nothing is working?
If you’re experiencing solid lights on the hub then it is an indication that your DIP switches
are not in the correct position. Disconnect power, adjust your DIP switches, and the only
light that should be lit is your RED power light.
How do I change the DIP switch to the correct speed of my fan?
You will need to disconnect power, make your adjustment inside the hub, and then
reconnect power.
Can you connect the Attic Fan Smart Control to a smart home system like Alexa,
Google Home, or Apple HomeKit?
No, in the current conguration the Smart Attic Fan Control cannot connect to a smart
home system. Smart home system control is not neccesary as the fan runs on it’s own and
hardly ever needs manual control.
What happens if I get a new phone?
If you get a new phone, you will need to pair your new phone to the Hub. This is very
easy to do if you still have your old phone, or have another phone in the home that is
currently paired to the Hub. If you have another device that is paired to the Hub, follow the
instructions on page 11 for Pair Mode. If you do not have any other devices in the home
that are paired to the Hub, you will need to press the physical Pair button on the Hub.
