Before you buy — quick checklist

  • Confirm your spa is a Sundance 680 Series model — check the serial tag on the equipment bay door
  • Verify your spa was manufactured in 2007 or newer, as earlier 680 Series models may use a different keypad revision
  • Confirm your spa uses a 2-pump configuration, as this keypad is designed for 2-pump control interfaces
  • Inspect the existing keypad cable connector and pin count to ensure it matches the 6600-651 before ordering
  • Check whether the issue is the keypad itself or the control pack — a keypad will not fix faults originating in the main board

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