Welcome to Backyardplus! In this post, we show you how to download spa software and format your USB drive for those that are updating their control box software.
What You Will Need:
- Visit backyardplus.com and purchase the spa software download here. Select OPTION 2 and input your spa’s serial number so we can determine which spa software your tub requires.
- Purchase or locate a 2.0 USB drive that is less than 8GB and formatted to FAT 32 (steps below)

How to Format USB
Step 1:
- Insert your USB flash drive (less than 8GB in size) to your USB port on your computer
- Open your windows explorer and locate the drive

Flash Control Box Service, IQ 2020 Spa Control System (Eagle & Hawk)
There are two control boxes that will not work unless the correct software is uploaded via USB to the control box unit. Item 76836 (Eagle Control Box) and item 76840 (Hawk Control Box). Each tub needs its own specific software uploaded to it in order for the box to work when you install it on your hot tub. When you buy this service from us, we will upload the correct software according to the serial number provided and we will also program your hot tub’s control panel settings into the new control box you purchase from us so that installation is a breeze. Please contact us if you have questions 805-541-9000.
