I unfortunately have purchased a used JNJ spa. While all of the pumps and the heat seem to work, there are a number of things like the lights and ozonator that are not hooked up. I have no wiring diagram or owners manual so I don't know where anything plugs into the control panel. Secondly, the temperature sensor doesn't seem to work so while the heater will come on if you turn the setting up high, there is no way for it to shut off as the temperature reading jumps continously. Can anyone help me out? If you have a JNJ spa, a picture of the inside of your control box would help me go in the right direction. Thanks!
