About this topside/keypad

The MQ554 7/8 Button Spaside Control is a genuine OEM replacement control panel designed for Marquis spa systems. This control unit features a 7/8 button configuration and comes without an overlay, allowing you to reuse your existing overlay or purchase one separately. The compact design integrates seamlessly with your spa's control system to manage essential functions including pumps, lights, and temperature settings.

At Bubbles Supply, we guarantee this control panel delivers an exact fit for your Marquis spa with our precision-matched OEM parts. Every MQ554 control ships the same day when ordered before our cutoff time and includes our comprehensive 1-year warranty for complete peace of mind. Before installation, verify your current control's part number matches MQ554 and ensure your overlay is compatible with the 7/8 button layout for proper operation.

Before you buy — quick checklist

  • Confirm your existing topside control is labeled MQ554 — cross-referencing by button count alone is not sufficient
  • This unit ships without an overlay — verify your existing overlay is compatible with the 7/8 button layout before ordering, or source a matching overlay separately
  • Check the ribbon cable connector on your current control to ensure it matches this replacement unit
  • Locate the control pack model in your spa's equipment bay and confirm it is designed to work with the MQ554 topside
  • Inspect the mounting cutout on your spa cabinet — dimensions must match this panel's footprint for a flush fit

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