Spa Boy Generator (pre-2020)

The SpaBoy Generator (pre-2020) is the replacement SpaBoy controller for older Arctic Spas equipped with the pre-2020 Spa Boy hardware. The generator talks to the salt cell, reads the ORP/PH probe, and decides when to fire the cell to maintain sanitizer levels.

*yours make look like a blue dome, instead of like the picture here. Trust. This is the one you need if your spa is older than 2020.
