Cag,
The way things should work is that your salt cell's Power center only get power when the EasyTouch's Pump/Filter relay is closed.. The Pump/Filter relay will only close when you are in the Pool mode or Spa mode.. I suspect that is why you have no lights on your salt cell...
Tell me more about your SuperFlo VS.. Is this an old pump? The newer ones all have RS-485 control and connect to the EasyTouch.
If you are going to use an actual Actuator that mounts to a Jandy style valve, you do not need a relay. Actuators have a three pin connector that connects to the main card in the EasyTouch. You can use the Aux 3 button on the main panel, but you are just wasting the relay. You can use a Feature Circuit to turn the bubbler on or off if you want.
Thanks,
Jim R.
