I recently had the two actuators replaced do to faulting wiring (the pool/spa main drain suction and pool/spa return actuators). When the new actuators were replaced on both the “spillover” feature that usually retuned water from the spa to the pool is now opposite. When I turn on the spillover feature the Jandy actuator actuates the pool/spa return water and return water to from the POOL to the SPA and NOT the main drain suction as it did before from SPA to POOL. The dip switch #3 is turned on as well. Could it be the actuators were placed in the wrong AUX on the iAqualink?

To give you some context of our pool and spa setup. The pool and spa are two bodies of water running on the same filter pump. They are on a schedule and alternate filtration on different times of the day. The main filter pump runs 24hrs per day and also adjusts RPM's throughout the day as well.

I hope all this makes sense.....

Pool equipment setup:
  • Jandy Filter Pump - both pool and spa on same pump
  • Jandy Heater for both pool and spa
  • Jandy SWG for both pool and spa
  • Jandy Actuator value on main drain/pool/spa suction
  • Jandy Actuator value on pool/spa return
  • Cyclone filter/Jandy pump for rain curtain
  • Jandy pump for secondary water feature
 
It saves the setting by virtue of the toggle reversing switch being in the other position. It will stay reversed as it’s a mechanical switch with two positions.
Ok. I will go ahead and give that a try and manually toggle the actuators after I click on “spillover” within iAquaLink. Since the main drain in not actively doing anything in spillover and I want that one to activate will it mess up the pool and spa modes as well? Will I need to adjust those after?

Will I have to adjust each actuator after I press pool mode or spa mode as well?
 
I re-read your original post and I'm not completely sure that I understand what you are describing. Yes, it's also possible the valves are plugged into the wrong spots.

You just have to go out and look at the valves when you switch the different modes between Pool, Spa, and Spillover and identify which valves are doing what in each of the modes. Look at the physical valves and see what's happening. When going from pool to spa modes both the inlet and return valves should move positions. If the water is going where you expect it in both pool and spa modes then the JVA toggle switches are in the right positions. When you put it in Spillover move the return valve should turn. If the inlet valve is turning instead the valves are plugged into the wrong sockets on the main board and the two connectors will need to swap sockets.

Thank you for all your help! The JVA were backwards in the return/intake on the main panel.
