SOURCE: Trying to replace Intermatic with Utilitech inwall

The wires on your new switch are intended for black = power .. white = neutral . and red = lights .. with two black wires on the old switch I am assuming that there is a bundle of white wires in that wall box, the white timer needs to join that bundle ... then you need to determine which black wire is the power from the electrical panel ( voltage tester) and connect to the black timer wire .. the red timer wire connects to the other black wire in the wall..

Please Vote !!

SOURCE: Utilitech Wall Timer #0192773 does not switch

Old timer: Intermatic EJ500 & ST01C timers have a battery. Battery operates the clock motor. Red wire is for 3-way circuit [a hallway with 2 switches is a 3-way circuit].

Utilitec timer, clock runs on 120Volt circuit instead of battery. So clock has to have power.

How to connect wires:
Black timer wire connects to hot wire from breaker box.
Red (or blue) timer wire goes to landscape lights.
White timer wire connects to white neutral wire [or if no neutral is available, connect to bare ground wire].
Green timer wire goes to bare ground wire.

How to find black hot wire and white neutral wire inside box
: Disconnect and separate wires so you can test. Use ordinary tester. Power is on. There is only 1 black hot wire inside each electrical box. Test each black wire to bare ground until tester light comes on > that identifies the black hot wire. Next, test black hot wire to white wires until tester light comes on > that is the neutral wire. Exception: This test does not necessarily work with 3-way switches since they reverse each time switch is thrown.

SOURCE: I am replacing an old intermatic model EJ341

GE 15086 is a 7-day programmable timer. It has more wires than spring-wound timer because clock motor runs on 120V circuit, just like ordinary electric clock. The clock on spring wound timer operated by a spring.

If I understand correctly, the old timer has 2 wires. One of these wires is the Hot wire ... and that wire will connect to GE timer black wire.
The other wire from old timer goes to Load ... and that wire will go to GE timer red wire.

Instructions on a lot of these timers say, it timer doesn't work, then reverse the two wires described above ... this is because timer only works when Timer black connects to Hot.

You can also turn on power and test each wire that came off old switch to bare ground wire. When tester lights up, that is Hot wire.

GE timer Green wire connects to bare ground wire.

Moving on to GE timer white wire. This wire is necessary for the clock to run. This wire connects to Neutral wire which is usually white. You can test for Neutral by testing Hot wire to each white wire in box ... when tester comes on, that is Neutral.

If you do not have a white Neutral wire, then connect GE timer white wire to bare ground wire. This is not code, but it will work fine until you hire electrician to run Neutral into box.

SOURCE: New intermatic T101 timer problem - timer is not

Manual override lever is good overall test of T101 120Volt timer.
T101 timer has 3 terminals: A 1 2

See wiring diagram on following link:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T101

Electricians test, they don't guess.
So test your wire:
Separate all wires for testing.
Use ordinary 2 prong tester.
Tape wood sticks to tester leads to keep hands away from power.
Stand on dry boards. Do not hold or touch anything metal.
Turn power ON.
Test each wire to bare ground wire.
Tester lights up on Hot wire. 120V circuit has only 1 Hot wire. If you have 2 Hot wires, you might have 240Volt circuit and need T104 timer. If circuit has 1 Hot wire, then that Hot wire must connect to terminal 1.
If you have NO Hot wire, then check circuit breaker.
Hot wire is identified.
Now test Hot wire to all other wires, except bare ground wire.
Tester lights up on Neutral wire. Neutral wire must connect to terminal A.
If you have NO Neutral wire, then additional wiring is needed, or circuit needs further testing to see what type of wiring you are working with.
Bare ground wires connect to green ground screw.

Notice there are small white wires also connected to terminals A and 1. These small white wires power the 120V clock motor. With Hot on terminal 1 and Neutral on terminal A, the clock motor will run, and yellow dial will rotate.

If timer dial does not rotate after connecting Hot ans Neutral, then test voltage across Hot and Neutral to make sure it reads 120V.

Your circuit should have 2 wires remaining.
These wires go to 120Volt load (fan, light, motor)
Connect these two wires to terminals A and 2.
Try manual override.
If Load turns ON-OFF, then timer is wired correctly.
If Load does NOT turn ON-OFF, then reverse Load wires on terminals A and 2.

Is this new timer installation, or older timer that stopped functioning?

1) Copy following link to help identify timer, download manual:
http://waterheatertimer.org/Intermatic-timers-and-manuals.html#E1020

2) If this is new installation, then check wiring for single pole installation. This timer will not work for 3-way switching.
http://waterheatertimer.org/How-to-wire-timers.html

3) If timer worked before, and now clock motor has stopped working:
Turn power off, use compressed air to blow out timer, then see if you can spray highly flammable vapor from WD40 can into the motor.gears.

4) There are replacement trippers for this timer, but no replacement clock motors.
Buy another single-pole in-wall timer.

You have Intermatic 240Volt sprinkler timer.
http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/r8816p101c%20-%20english.ashx

Timer relay has 4 wiring terminals: from left to right 1 2 3 4
Red wires from switch connect to terminals 1 and 3
Red wires to pump connect to terminals 2 and 4
Since circuit is 240Volt, red wires from switch can be connected in either order. Same with pump.

Rain sensor terminals don't have any wires, unless you but separate rain sensor.

Have only two wires how do i do?


You are apparently replacing a single switch, which only requires two wires (plus ground). The following directions are straight from the Intermatic directions that you can find at the link further below:
If a Single Switch Setup: Connect one of the two wires from the wall to the black wire from the switch timer, using the twist connectors provided. Connect the other wire from the wall to the blue wire from the switch timer, using the twist connectors provided. NOTE: The RED wire is not used in single-switch installations. Cap with a twist connector.
Connect the GREEN wire to the grounding screw in the box. If a plastic box, connect to ground as supplied. Make sure all twist connectors are tight

Is it possible to connect a digital timer(4 wires) to lite fixture with two switches? The switch I am trying to connect to is three pole and a ground


If I understand correctly, your switch has 3 poles, which makes it a 3-way switch.
You confirm this by saying light fixture has two switches.

There are two brands of in-wall timers that will work in 3-way situation. Intermatic and Aube. But only specific models of these timers work for 3-way.

The Intermatic EJ500 and ST01C battery-operated timers can work with 3-way switch. But wiring is tricky to impossible in some cases without extra wiring.
http://waterheatertimer.org/ST01C-program.html#ST01C


The easiest timer to wire for 3-way switch is Aube model T1032 which is a 500 watt timer.
http://waterheatertimer.org/Aube-timers.html
T1032 manual:
http://waterheatertimer.org/Aube-T1032-timer.pdf
geno_3245_147.jpg
Look at the wiring diagrams carefully.
Note that you are replacing one switch with the timer.
The second switch needs additional jumper wire added to circuit between dark-colored screw and the brass-colored screw that connects back to #1 wire from the timer.

Add a comment if you have this timer, or buy this timer, and need help with wiring.

Flickering bulbs


You posted under EJ500 Intermatic battery-operated timer.
If you have different timer, add a comment.
I have tested EJ500 timer.

A) If this is new single-pole installation and lights click on-off when timer turned on, then you connected red wire where blue wire should be connected.

Manual says for single pole switch:
Timer-black-wire to Hot; Timer-blue-wire to Load (lights)
Here's how to wire timer correctly:
1) Timer-green-wire connects to bare ground wire.
2) Switch has 2 wires. Take switch wires and connect them to timer-black-wire and timer-blue-wire. Choose either one for now.
3) Put wire nut on red wire.
4) Turn on electricity, and push ON-OFF button. If lights come on, timer is wired correctly. If lights do not come on, then reverse timer-blue and timer-black wires.

B) If you are replacing 3-way switch, view wiring diagrams shown on link below, and then add a comment saying exact color of wires. To wire this timer for 3-way can require additional wire between switches. This is because EJ500 blue wire must always go to Load (light, fan, motor)
http://waterheatertimer.org/ST01C-program.html#EJ500-wire

C) If this is older timer that stopped working, check your bulbs. Then check timer battery. Manual says if timer stops working and bulbs are good, and battery good, then reset timer and reprogram. How to reset timer. Press reset button while holding down Next/ON-OFF button.
EJ500 manual has long list of programming instructions: Add a comment if you forgot parts of programming.
