K100 Controller | Evolution Plus Series

A hot tub four-wire light controller is an electrical component used to manage the lighting system within a hot tub. It typically consists of four wires: Live/Hot Wire, Neutral Wire, Ground Wire, and Load Wire. The controller allows users to turn the lights on and off or change light settings, depending on the specific model. The four-wire setup is typical for systems that require a dedicated circuit to manage the lighting separate from other electrical components of the hot tub, ensuring safe and reliable operation.
