2. Copy the AP1 file to the “Upgrade” folder.
3. Copy the HTTP folder to the root directory and overwrite the existing files.
4. Disconnect the USB cable from the controller. The upgrade process will automatically start.
5. Once the upgrade is complete, the screen will display “Upload successful” and return to the main
screen. This may take up to 5 minutes.
6. Power cycle the controller by turning off the breaker and turning back on after a few seconds.
