PWA: 1995-1997 850 w/PermaClear 1.28FB
6600-017, Sundance 850 Circuit Board 1995-1997:1&2 Pump Systems with PermaClear.
Permaclear is a Circulation Pump that would be hooked up to the inlet side of the heater. Small pump is gray, red or black.(Eprom Rev. 1.28FB included). A circulation pump is not one of the main spa pumps but is a small pump like a Grundfos or Laing Pump.
Sundance Spas used the 6600-017 and 6600-018 as the same board many times and would replace the eprom to the system.
To help clarify: Circulation Pump Systems have used Eproms with 1.28E, 1.28F and 1.28FB. So if your board has on of these Eprom chips (usually starts with REV and located on a chip on the board), then you have a system with a circulation pump and this is your board: 6600-017.
A Non Circulation Pump System used an Eprom chip with a 1.29 number, so if your board has an Eprom chip with a 1.29 (usually starts with REV and located on a chip on the board) then the circuit board you need is this one: 6600-018
Technical Note: 6600-023, 6600-028, 6600-017, 6600-018 are the same circuit boards with different eproms. Must use the Eprom that comes with board when replacing board.
This Circuit Board was used on the following models and years: (Please note that you must verify that this is the board you have on your spa)
