    Multi Location Dimmer Install

    I installed the 2 companion dimmers with no issue. However, when I went to install the master controller and pulled the existing switch, it has 4 screws on the switch with 2 red and 2 black wires going to it and no ground.Please describe how I would connect to your controller. MACL 153MLRHW.

    Hello larklight,Please see page 2 of the wiring diagram @ for a good visualization of the wiring. You'll want to take both of your red wires and attach to the blue terminal screw -> YOU WANT TO WRAP ONE AROUND THE TERMINAL SCREW AND PUNCH THE OTHER IN RIGHT NEXT TO IT.You'll take one black wire and connect it to the brass terminal screw and the other black wire to the black terminal screw --> DOESN'T MATTER WHICH GOES ON WHICH.If you have any issues with this installation, please reach out to us at our 24/7 technical support team @ 1-888-Lutron1 (588-7661) Hope this helps! -Justin F.
