I have an older spa tech tub that I have set up, but it will not respond... there is one brown wire coming from the GFCI unit in the contol panel that is not hooked to anything... does anyone have any schematics or wiring diagrams for this...
Model# ST650 - RLP ?

Hey guy, the spa pak on my tub is by Brett Aqualine... it can be hooked up either 120/240... does that help?
