Chip Number: PHX05R1(x) (52903)
NOTE: You will be sent P/N 52532, it is the same exact board with one slight difference. If you have a stereo system that is plugging into J17, you'll notice that on the 52532 there is no plug there.
What you would need to do, is cut the 4 pin white plug off and connect the Green to Ground, White to Neutral and Black to Red AC.
Otherwise you will need to order the circuit board from a Phoenix Dealer.
It is very important that you do not order a circuit board based on looks, several boards look alike but have different software or chips. It is the chip that drives the board and gives it its unique functions. To correctly identify a circuit board the chip number should be used to identify it. It can be found on a white sticker near the center of the circuit board. Another number that is helpful in identifying a Balboa Water Group circuit board is the five digit number found on most boards (5****).
