The Balboa circuit board (part#: 53544), fits the Balboa VS510SZ Controller and EL2001 M3 Systems by Balboa and is an add-on board to run a second single-speed spa circulation pump. Also known as the mini pump 2 board, this balboa expander board measures 3-1/8" x 1-5/8" and functions as a single relay pump 2 extension circuit board. Located on top of the heater on M3 systems, or Balboa VS systems with two pumps, this Balboa Mini Expander board comes with two wire connectors.
Spa circuit boards should not be ordered by size or appearance – but by matching the chip number and/or manufacturer part number.
