Can someone offer any guidance on what we may be doing wrong? I looked at the instructions that came with the unit and the instructions I was able to download from Lutron, and both are different, yet confusing.
Follow these instructions, and remember the series of your GRX.
GRX-3100 would be the same as a GRX-MR.
This device was INTENDED to be used in retrofits in the instance where a secondary location was wired for 3-way control to traditional switches.
This is supposed to work for exatly what you have...
As far as the multiple instructions, you may have seen the other diagram for the 4000 series, which has dedicated SSA in and out terminals so you do not have to tie to the hot lead.
Use the diagram at the top of page 3 of this document.http://www.lutron.com/grafikeye/specs/ntgrx-1s.pdf
They seem to show the accessory dimmer connecting to a 2 way switch in both instances and also they show it using the SSA connection on the actual dimmer.
Any help is appreciated.
What?? I don't know what the "2-way switch" reference is about...
The fact that is does SOMETHING would lead me to believe that it is hooked up ciorrectly, but PLEASE RE-CHECK THE WIRING.
If there is a wiring problem, I would bet that you are somehow mis-using the carrier for the 3-way circuit that was already wired between your boxes.
Turn off the power to the circuit and do some continuity testing to verify that the wires you are using are what you think they are.
Even though I would like you and/or the electrician to double check your wiring anyway, it sounds like the GRX may be in programming mode while you are trying to operate it.
