Replacement Spa Control Systems.

I haven’t purchased one of these controllers yet, but they seem to be the best deal out there.

Not only do you get a new controller system, control pad and heater, but you also have the ability to diagnose the system just by looking at the LED’s (Lights) on the plugs, and you can mount the heater away from the actual controls! This would be wonderful for someone that has a hot-tub mounted under a deck, because you can put the controls in a place that is more accessible to you, while keeping the actual heater where it needs to be.
