An auxiliary topside panel can make a spa much easier to use when you want control available from more than one position. This AX10A1 auxiliary panel is designed for that purpose, giving compatible systems a dedicated secondary control point without requiring the main panel to do everything.

Because this version is supplied without the overlay, it works well in setups where the matching face is handled separately or where the installer needs to pair the panel body with the correct overlay for the exact final function layout. That flexibility can be useful in replacement work where the existing visible interface has to be matched carefully.

When an auxiliary panel begins to fail, the spa can still run, but convenience drops immediately. The secondary control point is often there to make common adjustments easier from a certain seat or side of the spa, and when that access is lost, the whole setup feels less thoughtful. Replacing the panel restores that convenience directly.

For homeowners, the biggest benefit is practical. A working auxiliary panel means less reaching, less walking around the spa, and a more natural way to make everyday adjustments where they are actually needed.

In the proper AX10A1 application, this panel helps bring secondary control back into the experience and gives the spa a more complete and useful layout overall.

  • Auxiliary topside panel for compatible AX10A1 systems
  • Supplied without overlay for application-specific matching
  • Restores a secondary control point where convenience matters
  • Useful when the original auxiliary panel is worn or unresponsive
  • Helps make everyday spa adjustments easier from more than one location
