I currently have an Intermatic T101 Timer Installed at the Breaker Panel which controls an entire circuit that I plug outdoor LED Christmas lights into. I want to replace this timer with an Insteon device to make it easier to control my lighting schedule. What would work best for what I want to do?

I would like to replace with Insteon so I can keep both circuits in unison as well as the Christmas trees that show in the front windows.

Thanks Again for all the Help

Your understanding is correct.

I probably could asked my last question more clearly:

Can I think of it as if there are 2 cables:

Cable 1 is the cable that goes to my timer. This cable has a connection to the common bus bar (white wire), a connection to the ground bus bar (copper wire) and a connection to the circuit breaker (black wire).

Cable 2 is the cable that feeds my outdoor lights. This cable connects to the common bus bar (white wire), a connection to the ground bus bar (copper wire) and a connection to the breaker via the red wire is ĎHotí when the timer is ĎOní.

The only place that the white wires and ground wires for each cable connects is on their respective bus bar.

Am I understanding this correctly? If I am then I feel confident enough to remove my timer and connect the switch once I verify what you said about the red wire in your previous post.

The neutral (also referred to as the common)wire also continues to the load. The ground wire continues to the load's ground connection.

Here's a link to the manual.

Thanks stusviews- I like the idea about the red wire. It will confirm it's purpose.

On last question:

The circuit that the timer controlled. Does the common and ground wire for the outside circuit make their connection on the electrical bar. Is that why only the red wire continues to the outside circuit?

Thanks for all the help.
stusviews Posted - 12/30/2017 : 4:37:05 PM
One last concern. Disconnect the red wire. (Turn power off first, then back on.) Does the load fail to turn on? If so, then you're good to go.

Also SPST (single pull single throw)

Iím sorry - it is Intermatic T101.
stusviews Posted - 12/29/2017 : 3:07:38 PM
What you indicated appears correct, but you gave two different model numbers for the Intermatic timers. Do you have one of each?

Also, T100/T101 is a bit generic, there are different specific models. Do you have more model number information? Just to be sure!!

Let me ask this question differently:

I have an Intermatic T100 Timer located next to the Electrical Panel

The Timer is connected to the Electrical Panel with a cable 12-3 w/ground

The cable is wired to the timer as follows:
1. the ground wire is connected to the timerís ground terminal
2. The white wire is connected to the timerís ĎAí terminal
3. The black wire is connected to the timerís Ď1í terminal
4. The red wire is connected to the timerís Ď2í terminal
Note: the ĎAí and Ď1í terminals also feed power to the timer.

Could I replace the timer with a INSTEON REMOTE CONTROL IN-LINE ON/OFF SWITCH 2475SDB

I would connect each of the wires to the switch by color I.e. white to white, black to black, red to red and ground to ground.

I would then control the switch with my ISY994I. I would control it like I currently control all of the other Insteon wall switches I currently have via Mobilinc App and also write programs to control the 2475SDB Switch by time or event.

Would the 2475SDB Switch turn my circuit on and off like my timer currently does via Insteon commands and programs?

Normally it is just Christmas lights but not limited to just Christmas lights. It could be anything that I use outdoors that needs to be plugged in. Therefore I need a 20A solution to replace the timers I now use. I could replace the breakers with 15A if necessary.

If I canít find what Iím looking for as described above I probably will use an Insteon 2634-222 plug in but it would require 6 of them to control all of my lights.

This year my light display won first price in my town so now I have $200 prize money to replace the timers.

You can use the existing timer boxes as enclosures. Select an appropriate Insteon device for each based on the load. Add both devices to a single ISY scene and then use a program to turn the scene on and/or off on schedule.

Only one program is required.

If the load is very low, then you may need to add a small incandescent bulb or unused wall wart to keep the lights from glowing a bit when turned off.

To better find a possible solution.

If it is Christmas Lights.
The Voltage and needed current that needs to be controlled, would help in a selection. Is probably not to great.
You want a plug in or hard wired in Insteon Controller?

pgesler Posted - 12/28/2017 : 06:08:32 AM
Yes I understand that there is a breaker for each circuit. I mentioned it because I want to replace both timers ( 2 circuits ) with something I can control through ISY994i (Insteon). Itís important for me to have both circuits turn on and off in uninson which canít be done with machanical timers. Also I want to be able to turn the lights on and off with my Mobilinc app.
stusviews Posted - 12/26/2017 : 3:37:01 PM
A bit of terminology: You mention a 20 Amp breaker, but you also mention two circuits. Each breaker controls one and only one circuit although there may be several outlets on that one circuit.

Two circuits requites two circuit breakers

If you turn off one circuit breaker, then everything on that circuit loses power.

So, which is it one circuit or two?
pgesler Posted - 12/25/2017 : 12:54:55 PM
Also - I have an UDI ISY994i
pgesler Posted - 12/25/2017 : 12:48:56 PM
The breaker is 20A. I will use ISY to manage. Iím also using Mobilinc HD App.

The left side of each outside receptacle is on a timer. One circuit is in the eaves and another circuit for the receptacles about 18 inches from the foundation.

I would like to replace with Insteon so I can keep both circuits in unison as well as the Christmas trees that show in the front windows.

stusviews Posted - 12/24/2017 : 4:04:52 PM
What do you use to manage Insteon devices, a Hub (which one, there are three), an ISY, software (which one), manual button pushing, something else?

What is the maximum load being controlled (amps, watts)?
