Programmable Timer on 3-way
Hi all
I'd like to install a programmable timer to turn my outside lights on and off. I've been looking at the Honeywell TI032 model.
The problem is, I need to install it where there is currently a 3 way switch. Currently coming into the switch there is a red wire, black wire, another black wire to common screw on switch, and a ground wire. There are a couple white wires in the box (not attached to the switch) wire nutted together. I assume these are the neutral.
I'm not sure if this model timer will work for me. Can anyone provide some insight? If this one won't work, are there others you'd recommend?
Thanks!
Dave

The Honeywell timer should be able to replace your existing toggle switch. You may need to reconfigure the wiring at the switch or at the fixture, but you will not need to pull new cable.
We'll at least need to know the wiring at the other switch to give specific details, maybe at the fixture.
The existing wiring will have to match one of these diagrams:

I'm not sure if what I have does match the diagrams.
The toggle switch I pulled has 2 blacks (one to screw on switch marked common), one red, and one ground. No neutral connected to the switch.
I don't see a common in the diagram you posted. But I have no idea what I'm looking at anyway!
Thanks for the support Ben.

Let's call the switch you want to replace switch A. At switch A, you have two black wires, a red wire, and some white wires. How many white wires? Also determine how the wires are grouped into cables. Put a piece of tape on the black common wire so you don't lose which one it is. Are there any wires other than whites wirenutted together?
Check the other switch that controls these lights, switch B and let us know what wires are there, what they connect to, and how they are grouped.
Depending on what is at switch B, I also might need you to take down the outside light and check the wiring there, but hold off on that for now.
