I have 2 2000R on a PP DV in stand alone wiring. I can adjust the test timer and that works. I try and adjust the blue knob for the photocell to keep the lights off and they still com on with motion. I try and set it to keep lights on and same problem. I have the gray wire hooked to the blue on the PP DV and am using the yellow/white and blue/white but have also tried the black/white and blue/white. I have also tried working with just one sensor at a time but same results. What am I doing wrong?
