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 16. 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specication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.
Within this 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.

based on the attic temperature and humidity.
To activate Smart Mode, simply tap Activate
Smart Mode.
InSmartMode,therstparameter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 parameter
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 parameters, the last parameter
that is checked is the Turn Fan On humidity
level. If the humidity level in the attic is above
the Turn Fan On humidity parameter but below
the Turn Fan Off humidity parameter, the fan will
turn on at the Desired Speed.

4.3 FREQUENTLY ASKED QUESTIONS
WHAT PROTOCOL DOES THIS CONTROL USE?
This control operates over Bluetooth to connect to your phone. The control uses Wi-Fi for
rmwareupdates.
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 through average
household obstructions.
WHY ARE ALL MY LIGHTS BLINKING ON THE HUB AND NOTHING IS
WORKING?
If you’re experiencing blinking lights on all LED indicators on the hub then it is an indication that
your DIP switches are not selected, or multiple DIP switches are selected. 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congurationtheSmartAtticFanControlcannotconnecttoasmarthome
system. Smart home system control is not necessary 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 16 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.
