Lutron 3-way dimmer wiring in older house

I'm trying to add a dimmer to the family room in the older section of the house.

I pulled out the switch that I would like to put the dimmer on and there are 4 wires on three screws as follows:

top:
screw 1: red
screw 2: black
bottom screw
black + black

Now, the new dimmer switch has 4 different colored wires.
red
black
red/white
green

Is anyone familiar enough with these to let me know which wired to connect where?

-cheers

Only one wire per screw. Pigtails can be used to correct this.

On three ways you need pay attention to the odd colored screw. Move the wiresmover one at a time. Test for proper operation before changing the other switch.

With those Lutron dimmers they come in two styles. The one type you can put the dimmer in one location and use a standard three way switch in the other location.

The second type of three way dimmer requires the use of a companion dimmer in the second location.

It is explained in the instructions bur they are not easy to follow. You could post the exact model number of the switch you have there.

I worked it out with their customer service.

Red -> Red
2 Blacks -> Black
Black -> Red/White
Cap the green.

Now I just have to figure how to get rid of the buzz coming from the bulbs when dimmed.

That sounds like you have incandescent light bulbs. Sometimes those filaments can be pretty loud. You may have to try different bulbs.

The old watt miser or super saver incandescent bulbs couldn't be dimmed without them humming.....loudly.

The dimmer is connected to 2 ceiling fixtures with 3 bulbs each. There was a mish-mash of incandescent and CFL's installed and dimmed unequally. One of the CFL's sounded like a bees nest. So I went over to Sam's club yeasterday and picked up a bunch of dimmable 11w 2700k GE LED's (=60 watt) for $4.95/each and now everything is perfect.

It is so nice to be able to dim the ceiling lights now. This dimmer only goes down to about 20 percent. It doesn't dim all the way to 0%, even after using the internal adjustment on the switch.

This is my first LED purchase and I had to spend some time researching them. Thanks, again

-Cheers

You may have to reprogram the dimmer again. I've noticed that the end points don't always set correctly.
