Thanks @ajw22. I noticed that in the Jandy thread but if I'm correct, isn't AUX3 the pool light?In the Aqualink CLEANER uses AUX1.
SPILLOVER uses AUX3.
Spillover Mode
If you have a pool and spa you can enable the Spillover function with dip switch #3 on the main panel. When switch #3 is on then AUX3 becomes the spillover control. If you have any relay connected to AUX3 you need to move it to an available Aux position.
With Spillover turned on by AUX3 the POOL/SPA return valve will move to the SPA position. Water will be suctioned by the pool and returned to the spa.
The cam on the return actuator may need to be reset to fully close the spa return when in POOL mode.
I also saw that last nugget of info, that it may need to be reset. Not sure if that it the issue in my case. I'm still attempting to figure out what is connected to what as I learn more about the pool.
