    Lutron Motion Sensor wiring

    I got a Lutron Motion Sensor for my kids' playroom downstairs (At 4, 10, and 14, they haven't figured out that light switches can be turned off). The lights down there are controlled by two different switches. When I took out the original switch, I noticed there was an additional red wire, I am used to seeing only two black ones plus a ground wire. I was told to leave out the red wire and put a wire nut on that, so I did. The second switch overrode the motion sensor and controlled the lights. When that second switch is on, the motion sensor does blink the orange light and I can enter the settings I want (so I know the motion sensor is receiving power). When that switch is off, the sensor doesn't work either. I took out all the wires and put wire nuts on them and left the switch in just for looks but it does nothing, and the motion sensor doesn't work. I was told to put all the wires for the second switch into a wire nut to fool the motion sensor into working, and that ended up tripping the breaker. I should add that the second switch also had a red wire on it also. How can I fix this?

    Hi bzigler,It sounds like you are definitely dealing with a mis-wire.The first thing to check is the model # of the Lutron sensor you are working with. There will be a sticker on the side of the unit itself that will confirm the model #.If it's a Maestro MS-OPS2, this one unfortunately won't work in the 3-way application you have as it's only intended for single pole application with just one switch for the lights.If it's a Maestro MS-OPS5M, this is the that is good for a 3-way application. More than likely all that would need to be done is to ensure the wiring for both the Lutron sensor and remaining mechanical switch are as shown in the installation guide @ there are any issues with attempting to correct this wiring, please don't hesitate to give us a call @ 1-888-Lutron1 (588-7661) Hope this helps! -JustinF.
