I have a Jandy RS4 controller with all 4 relays in use (filter pump, 2-stage pump, jet pump, and light). I'm trying to add a waterfall pump that I can turn on and off independently. I saw somewhere that the solar circuit can be used to control an auxilliary circuit. Has anyone done this or have experience with this contoller. Is it possible to re-label the solar button in the Onetouch to say 'Waterfall'? Any help will be greatly appreciated.
