This board is for circulation pump systems (see 6000-125 for reference). Comes with a REV. 3.61 chip. If your circuit board has a Software Chip that begins with a 3, then this is the correct series board. Sundance® Spas has revised this chip several times, we send you the board with the current chip. If you have an older board without a Circulation pump or your board has a chip that begins with a 5, then you need a board with a Series Chip that starts with a 5. which would be the 6600-289 or other.

Sundance® Spas used the same board on different series but sometimes would change the eprom on the board to function on a different system, but not the part number on the board. So the part number on the board may be incorrect. Essential in getting the correct board is to look at the eprom. This is a small 1/4 inch by 1 inch (approx) on the board itself with a white sticker that started with REV. See info below in making the correct choice, if unsure then send a picture of the board with the eprom number visible. Also if your year and model is not listed below it is probably not for your spa. If you have the wrong eprom you can order the correct one on our site.
Note: 6600-722, 6600-724, 6600-042, 6600-044, 6600-289, 6600-286 are the same boards with different eproms on them.
