About this topside/keypad

The Balboa TP540 6-button topside control panel is a genuine OEM replacement part designed for Balboa-equipped spas requiring this specific control interface. This topside features six operational buttons for comprehensive spa system control and comes without the overlay, allowing you to reuse your existing overlay or purchase one separately based on your spa's button configuration.

As an exact OEM replacement from Balboa, this TP540 topside ensures perfect compatibility with your spa's control system. We guarantee an exact fit and back every purchase with our 1-year warranty for complete peace of mind. Most orders ship the same day for minimal downtime. Before installation, verify your existing topside model number matches TP540 and confirm the 6-button layout matches your spa's requirements.

Before you buy — quick checklist

  • Confirm your existing topside model number is exactly TP540 — check the label on the back of the panel

  • Match the cable connector type and pin count on your existing topside before ordering
  • Check the topside port location on your spa shell to ensure the TP540 form factor fits your cutout

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
