PCBs, Control boxes & Complete Packs FAQs

• What is a hot tub PCB, and why is it important?

  A PCB (Printed Circuit Board) is the main control system of a hot tub, managing functions like temperature, jet power, lighting, and filtration. If your hot tub isn’t responding correctly, a faulty PCB could be the cause.

• What’s the difference between a PCB and a control box?

  A PCB (Printed Circuit Board) is the electronic brain inside the control box, responsible for managing all functions. A Control Box is the enclosure that houses the PCB, along with connections for the heater, pumps, and sensors.
