I hope I am asking this question in the right forum.
I have a corridor lighted by a 4-way application which I am converting to a motion sensor system with a Lutron Maestro MS-OPS5M-SW sensor switch for “Location 1” and two companion switches, Lutron Maestro MA-AS-WH, for “Location 2” and “Location 3.” On Lutron's “Technical Support Wiring Tool Diagrams” (http://www.lutron.com/TechnicalDocum...93_Page_16.pdf), the picture of “Location 2” shows one RED wire from the wall clearly going to the BLUE screw on the Lutron Maestro MA-AS-WH switch. A second RED wire from the wall disappears behind the switch. I assume that means it goes to the same terminal (the BLUE screw) but connects not on the screw but into the "hole" at the BLUE screw location behind the switch. Is that correct?
Also, in the box with the Lutron Maestro MS-OPS5M-SW, there is included a six inch piece of yellow wire. I do not see it in the "Technical Support Wiring Tool Diagrams" for “Location 1,” and there is no yellow wire coming from the wall. What is it for?
Thank you.
