I am trying to install a Compupool CPSC16 salt system. I have a 120V supply and have converted the two items inside the unit as in the manual. Now for the electrical. I am using a GE 15306 timer. I have the pump up and running and am supplying the timer on the same lines. I know the green is ground and the black is the hot. What is the red when using a 120v? Is it neutral or is it another hot and the change in conncetions inside the system convert? Issue is when I hook the red up as a neutral I get no power to the salt system - remember the pump is running fine. Thanks for any suggestions.
