Our spa side controller (Jandy 4 button) has gone on the fritz and needs to be replaced. I haven't found much information online about replacing these units. Do the controllers need to be replaced as a single unit, re-pulling the wires from/to the power center? Or, is it acceptable to cut off the existing 4 button controller and connect the existing wires to the new controller? The Jandy/Zodiac website is dearly lacking in information.
If re-pulling the wires is the way it needs to be, what helpful hints can you pass along?
