I finally purchased a 1.5 hp 2 speed motor to replace my single speed hayward super 2. I have an aqualogic ps-4 for control with an available aux2 relay. I understand the wiring schematic but want to know the correct way to combine the line in and common wires to the new relay. Should I splice the line or can I add the new wire at the filter pump connection screw to the Aux 2 open relay?
I also have to add a 4th wire from the motor to my box. Is it best to just run a single 12g wire through the conduit? I am disabling the toggle hi/low switch as I need to use the aqualogic automation speed control as I have in-ground pop up cleaners and solar. Thanks for any information and help you may be able to provide.
