I recently replaced the circuit board for my Spa and am having some issues. The Heater will turn off after running for a while and will not turn back on unless I disconnect the power and reconnect it. Also the Main jets will turn on and continue to run for hours instead of just the few minute cycle period.

I'm wondering if these problems might be related to jumper/pin settings being set incorrectly. The new board I ordered had jumpers set differently than the old board (I needed a new board because the old one had gotten wet and short circuited).

I cannot find documentation anywhere that documents how the jumpers should be set. I've looked in my manual, the cabinet, and even searched online.

Any ideas where I can find this information, or thoughts on why it may be functioning like this?

Here's my spa info...

Model: Sundance 1999 Rio
Power: hard wired for 240V/50A
Circuit Board: 6600-027
