Before you buy — quick checklist

  • Confirm your control pack is a Balboa VS511SZ — the auxiliary keypad is system-specific and may not work with other Balboa control packs
  • Locate the part number printed on your existing keypad and verify it matches 52404-01 before ordering
  • Check the connector type and pin count on your existing keypad cable — confirm it matches this unit before installation
  • Verify the cable length from your auxiliary keypad port to the desired mounting location — extension cables may be needed
  • Inspect the keypad port on your control pack for corrosion or pin damage before installing a new keypad

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