Disconnect the fan(s) from the controller, and then tap FORGET on the Fan Disconnected screen.

Note: You will not see the Fan Disconnected screen if If you only had one fan connected. The controller is no longer connected to power after the CAT5 cable is disconnected.

Reconnect the fan’s CAT5 cable to the controller or to your other fans that are daisy chained to the controller. BAFCon will automatically detect the fan and start controlling it. To view all connected fans, tap the menu icon on the Home screen, and then tap FAN MANAGEMENT.

On the Home screen, tap the menu icon, and then tap CLOCK. Set the date, time, and time zone. The time will be displayed on the Home screen and on the screensaver (if enabled).

If you want to use the BAFCon Updates app to automatically update your controller’s clock and time zone, tap Automatic Clock Update on the Clock menu, and then download the app on your mobile device. Use the app to sync the mobile device’s local date and time to the controller.

1. Download the BAFCon app on your mobile device from the App Store or Google Play Store.
2. Open the app and download the update.
3. Take your mobile device to the controller you want to update and tap Update next to the controller name. The controller will receive the update from the app via Bluetooth. Make sure Bluetooth is enabled on your mobile device and on the controller. Bluetooth is enabled on the controller by default. 

Note: Firmware updates may take several minutes. The mobile device on which the app is installed will need to remain within Bluetooth range of the controller during this time.

At the top of the Home screen, tap either the fan name or ALL FANS to view the FANS screen. All connected fans are shown on the FANS screen. You can also view and manage each fan’s settings by tapping the menu icon on the Home screen and then tapping FAN MANAGEMENT.

On the Home screen, tap the menu icon, and then tap > FAN MANAGEMENT > Fan Name > RENAME. Enter a new name for the fan, and then tap ENTER.

Tip: If you have multiple fans connected to the controller and aren’t sure which one you’re renaming, tap IDENTIFY next to the box where you enter the new fan name. Follow the instructions on the screen. The controller will stop all fans except the one you are identifying. If all fans are already stopped, the one you are identifying will start spinning.

SmartSense is an optional BAFCon setting that eliminates the need for manual fan control. When enabled, SmartSense uses BAFCon’s built-in temperature and humidity sensors to maintain a consistent year-round temperature from floor to ceiling, maximizing comfort and energy savings. As the temperature rises with warmer weather, SmartSense automatically speeds up your fan to provide cooling. During cooler weather, SmartSense automatically slows down the fan to destratisfy the air, pushing warm air trapped at the ceiling down to the floor without creating a draft.

SmartSense is turned off by default. To enable it, tap SMART on the Home screen. Tap the thermometer icon at the top of the screen to set your ideal temperature. SmartSense will use this setting to automatically adjust the fan speed as ambient conditions change.

If you manually adjust the fan speed or turn the fan on/off from the Home screen while SmartSense is enabled, SmartSense will be disabled. To re-enable it, tap SMART. If you want SmartSense to resume automatically after a manual adjustment is made, you can enable this feature from the controller’s advanced SmartSense settings. Click here to learn about advanced SmartSense settings.

SmartSense is turned off by default. To enable it, tap SMART on the Home screen. To disable it, tap ON/OFF or adjust the fan speed from the Home screen. Click here to learn more about using SmartSense.

Advanced SmartSense settings let you set a minimum and maximum SmartSense fan speed and set SmartSense to resume automatically after a manual fan adjustment is made.

To access advanced SmartSense settings, tap the thermometer icon in the top right corner of the Home screen while SmartSense is enabled, and then tap Advanced SmartSense Settings at the bottom of the screen.

• Tap the slider next to Return to SmartSense to enable or disable the Return to SmartSense feature. When enabled, the fan will automatically return to SmartSense a set period of time after you manually adjust speed or turn the fan on/off. When disabled, the fan will not return to SmartSense after a manual fan adjustment is made (this is the default setting).
• Tap the + and – buttons next to Manual Override Timeout to adjust the number of hours until the fan returns to SmartSense after a manual adjustment is made. The default time period is two hours. A timer showing how long until SmartSense resumes will be displayed on the Home screen.
• Tap the + and – buttons next to Maximum Fan Speed and Minimum Fan Speed to set the fan’s maximum and minimum speeds when SmartSense is enabled.

No. All sensors needed for SmartSense are built into your controller. Click here to learn more about SmartSense.

To set up a passcode, tap the menu icon on the Home screen, and then tap PASSCODE. Tap SETUP next to the type of passcode you want to create. Follow the instructions on the screen. You can set up two types of passcodes:

• User passcode – Secures access to the entire controller and must be entered each time the controller is awakened from screensaver mode. People with user level access can turn fans and lights on and off, adjust fan speed/light brightness, reverse fans, and enable/disable SmartSense.
• Admin passcode – Secures access to the controller’s settings and must be entered each time the menu icon (general settings) or thermometer icon (SmartSense settings) is tapped. People with admin level access can adjust all controller functions. Note: If both a user and admin passcode are set up, the admin passcode will work when the controller prompts you for either passcode.

Tap the menu icon on the Home screen, and then tap PASSCODE. Tap EDIT next to User Passcode or Admin Passcode. Tap CHANGE USER PASSCODE, REMOVE USER PASSCODE, CHANGE ADMIN PASSCODE, or REMOVE ADMIN PASSCODE and follow the instructions on the screen.

Note: If you set up an admin passcode, you will need to enter it to access the controller’s settings.

This is indicating a fault code. Big Ass Fans have built-in checks that look for both internal and external faults.

If the fan currently has a fault, the LED indicator will blink a set number of times, then pause for four seconds. The number of times the indicator flashes before pausing indicates the fault. View the full list of fault codes.

Airfoil noise occurs when airfoils are not tightened to the specified torque. Disconnect the fan from power and disassemble the cage. Tighten the airfoil hardware to 29 ft·lb (39.3 N·m). Replace the cage before connecting the fan to power. If popping still occurs, contact Customer Service.

To replace a fuse:

1. Unplug the fan.
2. Remove the six screws to open the controller enclosure.
3. Gently twist and pull out the fuse holder and replace the fuse.
4. Reinstall the fuse holder.
5. Reattach the enclosure cover.

Suitable fuse replacements:

• Bussman S505 Series

If the misting system has not been used for a long period of time, water left in the system may produce a musty odor.

• Clear out the misting system by running fresh water through it for one minute before resuming normal operation.
• If the misting system will be unused or stored for more than one week, drain the water out of the system after you are finished using it. Click here for details on draining and storing the misting system.

This is most likely a fault code. Big Ass Fans have built-in checks that look for both internal and external faults.

If your keypad reads “OU”, this means that the fan received a power spike from your building’s power.

Regardless of the fault code, press the red “Stop” button to clear it.
