3-2 Operating the QuietCool Smart Control App
When you first connect to your QuietCool Smart Attic Fan
Control, your attic fan will show up in the list of available fans in
the app.
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.
Tap on the fan to start the setup process. Once you tap on the
fan, you will go to to the Fan Setup page.
On this page, you will be able to change the name of your fan.
Simply tap the current fan name and you will be able to name it
whatever you would like.
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 specification of the fan you purchased.
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
Temperature & Humidity Settings 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 settings changes on the fly.
Temperature
• The settings you choose in this section will change what
temperature the fan will come on at each set speed.
• Tap on either Low or High speed to adjust the temperature for
each speed.
• Note: Low Speed must be set at a lower speed than High
Speed.
Humidity
• Turn Fan Off: This is the humidity percentage that will cause
the fan to turn off. For example, if it is set at 90%, the fan will
turn off if the humidity in the attic is 90% or higher.
• Turn Fan On: This is the humidity percentage that will cause
the fan to turn on. For example, if it is set at 70%, the fan will
turn on if the humidity in the attic is higher than 70%.
• Desired Speed: This is the speed the fan will use if the
humidity causes the fan to turn on.

Once setup is complete, tap Done in the Fan Setup page.
Now you can tap the fan on the home page. You will be taken to
the Fan Control page.
On the Fan Control page, you will see the current fan status, the
current attic temperature, as well as the current attic humidity
level.
You also have the option to Activate Smart Mode or Activate
Timer Mode. You can also go into the settings of the fan and
adjust the settings that you setup in the first step.
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.
Regardless of the attic temperature, if the current attic
humidity percentgage is over the Turn Fan Off Humidity setting,
the fan will shut off. Once the humidity in the attic is back under
that setting, the temperature sensor will become active again to
control the fan.
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.

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 first 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 configuration the Smart Attic Fan Control cannot connect to a smart home
system.
