I have a 3 way switch, can this timer be installed with 3 existing wires?

Sorry, I use the timer on the only switch that controls that particular light. As for three-way operation, the only things I would know would be what is in the instructions.

Yes. A 3-wire hook up is easy. Other timers which serve the same purpose which I purchased at retail all had a needlessly complicated 4 and 5-wire hookup. Returned them. With the Intermatic just follow the schematic that comes with the timer that is specific to the 3-wire hookup. Good luck!

I was replacing an old timer, same model, that stopped working. I had an electrician install it. It did have 3 wires. In addition to replacing one that no longer worked, I appreciated the instructions that came with the new one. Never could figure out how to set the on - off for the exhaust fan, until I got the new one. But I can hardly spell the word electricity, so can't help you with your technical question. Hope it works for you.

Yes if the light has a ground going to it. If so cap the ground wire and connect the hot wire to the switch. If there is not a groumd wire going to the light it will not work.

Greetings Stephanie: This is a single pole switch. It will not work in a 3-way switched circuit. Please note that this switch requires hot, load, and neutral connections. The neutral is required to run the clock motor.

I would guess not. Three way switches use a third connector for a traveler wire. I don't believe this unit has that feature.

I wired mine clock/timer controlled by DC - switch side DC. It works that way as well.

I believe you can if you install an identical SwitchLinc in the other location as well. I've thought about doing this, but I'm afraid the 3 way wiring is a little advanced for me. Not to mention that you need to use twice the number of SwitchLincs.https://www.youtube.com/watch?v=twEvh3Vua8U

on mine the first switch is for 1,3,5 and 7. the second is for 2, 4, 6 and 8. you can connect them any way you like.

Yes. I wired mine to the existing switch. If you don't have one, just add one inline to your power panel.

I put in a 4 function switch but only had 3 wires. I left one wire unconnected. [My contractor left my 3 way Nutone switch in place when he replaced the Nutone fixture with Panasonic, and the Panasonic worked for a year (without being able to turn on the night light). When the light switch malfunctioned, I replaced it with the 4 wire switch.]

I believe it would work however, even though it is 3 way switch can only use 1 switch at a time. Hope this answers your question.

I don't believe it will work on a three way switch. It actually turns a standard switch into a three way system using the radio controlled remote switch. The wording on the description & instructions is confusing & a little misleading.

Yes you can with 3 wire cable from furnace junction box to the transfer switch. If you do not know how to connect it consult an electricianDon

Yes and no, you can set up up as a 3 or more way switch but you need a insteon switch or keypad at each location. You can not use the insteon switch with a standard switch in a 3 way configuration.

It's extremely simple. Just pay attention to the wiring as you remove the existing 3-way switch, and follow the wiring diagram in the box. It took me about five minutes before it was up and running.

I am not an electrician, but if you google "PLS750C1000 manual" you can see the wiring diagram for an Existing 3-way Install and follow as I try to describe why a jumper is needed. Starting from the right hand 3-way, power comes to the switch, is jumpered across the Common terminal and the Traveler terminal that goes to the timer switch's Line (black) wire. In effect, this bypasses the right hand 3-way providing constant power to the timer's Line, regardless of the 3-way's switch position. The 3-way's other Traveler terminal connects to the timer's 3-way (yellow) wire, and the 3-way switch basically acts like a single pole (regular on/off) switch. If you look at the electrical flow, it goes into the 3-way's Common terminal, then depending on whether the 3-way is switched one way or the other, power either goes to the timer's 3-way (yellow) wire or does not go. That is, the yellow wire is either "on" or "off". (For what it's worth, when the yellow wire is off, power is going through both the switch and jumper to the timer's Line (black) wire. When the yellow is on, power is going through only the jumper to the timer's Line (black) wire.) I have not confirmed this with Honeywell, but I believe the timer looks at its 3-way (yellow) wire for a change of state. When there is a change of state on the timer's 3-way (yellow) wire (from off to on, or from on to off), the timer sees that change and changes the state of the load from whatever it is currently to its opposite (That is, from on to off or from off to on). So, hopefully that answers why the jumper is needed on the other 3-way switch. And that also kind of answers why both travelers are not connected as they would be normally. It's basically because of the timer's design. I hope this helps. If not, I would do as another respondent suggested and call or email Honeywell. They were good at timely answering a wiring question I had, since my setup matches neither their Existing 3-way nor their New 3-way diagrams precisely.

It should as it is a 3 to 1 switch. Unfortunately I don't have a way to test that configuration.

No I don't believe so. The unit only has three wires, a neutral that allows the LED lights to work, Black is your line power in and your Red wire is your load out to your fan or light... I installed mine over a month ago And I already threw away the paperwork. If it has a fourth wire other than the ground then perhaps it can be used as a three-way switch.

Wire a 3-way switch. Or just disconnect the 2 wires and twist them together.
