GHL™ has taken the time to fully integrate the aF4 into their aquarium controller ecosystem. Head to their website for detailed instructions on how to setup the aF4 on your GHL™ controller!

IMPORTANT: The aF4 requires a 9-10V signal to trigger a feed cycle! At approximately the 1:03 minute mark in the video, set the feeder to 9 or higher!

Note: Make sure your GHL™ controller is updated to the latest version before attempting to follow these instructions.
