Why in the world would you use a wiring diagram that didn't come with the device to hook it up when it has a diagram that comes with it?? The Maestro devices use a connection to talk to each other and application of power to the wrong connection will ruin the device. The required connections for some of these devices changes from type to type as well so a type used only in pairs gets wired differently that a type that can have from 2 to seven controls.

If wired wrong initially it is likely you will need to replace one if not both units. Follow the wiring directions that come with the devices exactly - they are NOT 3 way switches.

Hook it up as it says on the box and it might work. Following directions supplied with the device usually works the best.

Thank you,

This is the 3rd set of Maestro dimmers I have hooked up. All the other ones have worked fine up until now. I think the dimmer itself must be faulty.

After looking at that wiring diagram above and looking at the wiring diagram that came with the dimmers, I think that it's fairly close to being the same. In fact, looking at my notes, I tried the wiring plan from the Maestro instructions. I think I may have a defective unit. I am going to get a replacement today to see if that fixes the problem.

The bottom line is that the wiring diagram above is incorrect. If the black and white wires are switched so that the white wires go to the brass screws and the black wires go to the black screws, this will represent how I originally wired it. That seems to be in-line with both the wiring manual I have and the Maestro instructions. However, it didn't work the first time.

As others pointed out, the MAESTRO isn't a 3-way and wiring up as one won't work. Further, neither the Lutron Maestro nor a mechanical 3-way switch is labeled the way you have drawn it.

There isn't a neutral to be had anywhere in either a 3-way nor a proper lutron wiring.

Connect the your traveller from brass to brass, blue to blue, and black on one dimmer to the incoming hot and the black on the other dimmer to the light. If I understand your drawing correct, you'll need to run on the third wire to the black screw on the remote since you've got the hot and load wires in the same box.

Yes thank you. I think I arrived at this same conclusion. In fact, I did wire it this way initially...but it didn't work. I am going to try a new unit with the wiring that you suggest.

Basically when it didn't work the first time, I looked at the other wiring manual and was briefly confused about the terminology of the white wire of the 14-3 cable being labeled as hot (I get it now). Also, the terminology from the Maestro instructions didn't mention the white wires being hot and it didn't mention hot at all, it talked about labeling one of the wires as "common" based on the color screw it was attached to. Since this is a new circuit, there was no original switch to check.

That is when I switched the black and white wires on the two switches. I see now this could not possibly work.

Actually there is NO legitimate white wire in this circuit. Remark that white one some other color (other than green).

Thank you. I admit to being confused about this initially, then it hit me last night as I was trying to go to bed.

Power is supplied to one of the dimmers, then it travels to the other dimmer through the (in my case) white wire that needs to be noted as hot.

So this means I originally had it wired correctly, and the unit itself must be bad. If that is true I am a very happy guy.

Thanks again.

"After looking at that wiring diagram above and looking at the wiring diagram that came with the dimmers, I think that it's fairly close to being the same."

Fairlky close doesn't count in electrical work.

Obviously close doesn't count. Did you read anything I posted?

I am posting a new topic to keep this less confusing now that I have changed things around.
