I bought a Leviton light switch timer. It has 5 wires coming out of it – Black, White, Yellow, Red, and Green.
The switch I'm trying to replace is in a box with 2 other light switches. The switch I want to replace only has 3 black wires running to it. How do I connect connect this?
Best Answer
First off, if there's not a grounded (neutral) conductor in the box, you cannot connect this device.
Based on your description of the wiring, it's difficult to tell exactly how your current switch is wired. If you're not sure yourself how the current switch is wired, it might be best for you to contact a local licensed Electrician to install the switch for you. If you have a basic understanding of your wiring; and/or electrical wiring in general, the following information (which can be found in the instruction sheet that came with the device) should be helpful.
Single pole installation
If this is a single pole installation (only one switch controls the lights), then you'll only need to connect 4 of the 5 wires.
3-Way wiring
This device is not compatible with standard 3- or 4-way switches. If you're going to use it in a 3- or 4-way setup, you'll have to purchase compatible vizia +™ on/off remotes.
3-way wiring with coordinating remote switch (VP0SR-10)
If you're pairing the timer with a coordinating remote switch, you'll wire it as follows.
3-way wiring with matching remote switch (VP0SR-1L)
If you're pairing the timer with a matching remote switch, you'll wire it as follows.
