If your system has a 6600-087 and the eprom chip that begins with a 5 (such as REV 5.54), then you have a 6600-287 board. 2002+ Jacuzzi® Circuit Board for: J-300 Series LED Circuit Board 6600-288 is for following models: 1. 2002-2006 J-335, J-345, 2005-2006 J-325 2. 2002-2003 J-325, 3.2007 J-325 (240 Volt Model). As of 2007 the J-300 Series are all LED models. 4. 2007+ J-365, J-355, J-345, J-335 5. 2008+ J-375 This board (6600-288) is for circulation pump systems (see 6000-125 for circulation pump). Comes with a Series 3.61+ chip. If your circuit board has a Software Chip that begins with a 3, then this is the correct series board. Sundance has revised this chip several times If you have an older board without a Circulation pump, then you need a board with a Series Chip that starts with a 5.
If you have an older board WITHOUT a Circulation pump (see 6000-125 for picture of circulation pump), then you need a board with a Series Chip that starts with a 5. This would be a 6600-287 board. ALL 6600-287, 6600-087 boards (without circulation pump logic, Chip 5.54) and 6600-288, 6600-088 (with Circulation Pump Logic, Chip 3.56 or higher) are identical but use different microchips.
