Using the GE/JASCO 45613 Three-Way Dimmer Set:
Over the last few months since I originally purchased these 3-way switches ready to install, I wasted lots of time and delayed this project literally MONTHS, fretting about how the instructions didn’t match my wiring, how existing switches didn’t have wires like the diagrams or documentation, and how I started and stopped and installed and un-installed things time and again before just sticking it out for about four hours today to successful completion.
Thus my “Here’s what I wish someone had told me in the first ten minutes” contribution to the forum.
This GE/JASCO Z-Wave is VERY DIFFERENT from a normal 3-way setup. Never mind it claims to be a drop in 3-way set. It does work ingeniously fine and will definitely APPEAR to function relatively as a normal three way. But there are some major differences, and it’s really an optical illusion at all since this really is a completely different animal from any normal 3-way switch set you may have ever installed before. The set has two pieces:
A) ZW3003 - One RELATIVELY NORMAL MASTER DIMMER switch, and
B) ZW2002 - One AUX "SWITCH" (totally useless on its own, btw). Though a switch of sorts, it's actually only a signaling device to send a little pulse over to its friend across the wire and say: "Hey, MASTER Ol' Buddy Ol' Pal, How 'Bout You Switch That Circuit For Me, Eh!?"
(How this AUX wires/works was truly the “Aha!” I was missing when starting this project. Ingenious key point to know!)
One other interesting point: Unlike “normal” 3-ways which flip position every time, these guys are always ON=TOP and OFF=BOTTOM. A minor point, but nice to understand since that’s very different than you might expect of a 3-way.
So, the two key points I wish someone had told me and saved me countless hours:
- MASTER side wires/works pretty much exactly as you might expect for a basic 3-way:
- Line
- Load
- Neutral ← thanks sumbarino for pointing out I forgot this one first edit. : )
- Traveler
- Ground
- AUX side is totally wacky from perspective of a “normal 3-way” switch:
- Line & Load get twisted together and capped off, unused by the “switch”
- Traveler attaches as normal
- Ground attaches as normal
- Neutral – This may be a “gotcha” if you have to fish around, find, and tap into NEUTRAL to attach to AUX.
Once I understood how this nifty AUX item was really working, it all made total sense, and I had the thing installed in ~ 5 minutes! But it took months of fretting and googling and reading and trying again and again to really “get it”. I had lots of normal electrical work un-learning to do first. : )
So: This is the quick guide for anyone else doing some of that same fretwork, just needing a QUICK START pre-read!
Good luck, and I’d like to hear of your success if this helps.
