The last two part numbers in the part number represent the version of the spa board. The higher number the newer the version.
This board now also serves as a replacement for 54381, but the following instructions must be followed: when installing the board, move every white wire on the new board to the same location as on the old board. Do not move any other wires, including the black wires. Push down every dip switch.
