Balboa WiFi module. Great condition. I found this to be a incredible device as you can fully control the Spa when away from home, brought my running costs down as I would drop temperature down between use them bring it back up that extra few degrees when heading home to use it. *** Please note if your Balboa Control Board only has one auxiliary port you would need to purchase a control board Y spitter, these are available online for £26 delivered from “aqua spa suppiers”, product code: 108013 if required. My Balboa Spa did not. You also need to have WiFi coverage in the area of your Spa as this connects to your WiFi network. ***
