First, I am not an electrician and can’t speak in ohms and AC; however, with the attached diagram, I hope someone can help me solve why my second 8-zone controller is not activating when the APP says that it is on. I think my problem may be with connecting all of my common wires together. I have a master valve and know that it must be connected to the red wires between two isolators, but the 3 white commons are throwing me for a loop. Help please! I created this powerpoint to show exactly how everything is currently wired.
