Help wiring a dimmer


Hi,

I am trying to replace two of my switches in the basement with a new Decora style switch and a dimmer. I disconnected one of the switches without marking anything, so that was probably my first mistake.

So what I have now is:

- Existing three way switch at the top of the stairs with a single 12/3 going to it.

- Another 12/3 where the old switch was and where I would like to add a dimmer.

- Based on what I have, I am assuming that I have it wired this way


Questions:

- The dimmer I am using is a Leviton ( http://www.leviton.com/OA_HTML/ibeCC...minisite=10025) and the three way instructions say

Connect wires per WIRING DIAGRAM as follows:
Screw wire nuts on clockwise making sure no bare
conductors show below the wire connectors. Secure each
connector with electrical tape.
• Green dimmer Ground lead to Green or bare copper wire
in wall box.
• Black dimmer lead to tagged Line (Hot) wall box wire
identified when removing old switch.
• Blue dimmer lead to Load wall box wire.
• Yellow dimmer lead to remaining wall box wire.

It also says

WARNINGS AND CAUTIONS:
• Use only one (1) dimmer per load. For remote operation, use Leviton Remote, Cat. No. TT00R-1.
Do not use a 3-way switch

And that's where I am lost

Help please!

This looks like a regular (NON 3 way) dimmer switch instruction...
that implies, but doesn't actually say, it wants a neutral wire as well.

It doesn't appear to have enough wires to work as a 3 way dimmer.

3-Way Dimmer Switches typically come with the following pre-wired leads:
Green wire - attach to the bonded ground wire(s) in the switch box.
Two Red wires - these attach to the "travelers" - the pair of wires attached to the two screws at one end of the regular 3-way-switch.
One Black wire -attach to the wire commonly found on the screw by itself on the regular 3-way switch, typically the Power or the Switch Leg leaving to the fixture(s).

The "optional" yellow wire is what's suppose to make it a 3 way, so there's a total of 4 wires, incl ground, coming out of the dimmer.

That particular dimmer requires a matching remote as the second switch, not a standard 3 way switch. You will either have to replace the 3way switch with the required remote or replace the dimmer with a standard 3way dimmer.

Help wiring a dimmer


So assuming that I can find a remote switch at HD, how does the dimmer get wired?

Just like the instructions say to do it.

This sounds like it works the same way as the PCS and HAI dimmers I've used. The main unit gets both the line and the load connections. The remote gets a hot and a "signal" line that it uses to send signals back to the main unit. That's what the yellow lead on the dimmer you have is for. You can make this setup work, but you'll have to make changes in the connections in the fixture box.

If you want to use a standard 3-way switch in the circuit, you've got the wrong dimmer.

I was reading it and as soon I did see the word " do not use the standard 3 way switch " I knew it right away that is what I called multi location dimmer switch so it will work with two or more dimmer in that fashion so you can turn it on or off at any spot plus can dim or brighten up at any location.

There is very sepecfic way to do this if you have switch loops that will get very tricky to address due the mulit location dimmers unit must have incomming hot source then outgoing hot source at the other switch location however you have to pay attetion to the conneciton colour format this is very important otherwise it will jamais (never) function at all.,,

I have done few of them also please make a note of connection at the luminarie location as well so you will know which colour you will dealt with it.

Merci,
Marc
