The usual connection for this type timer is the house black power to the timer black, the house white power to the timer white and the , the light black wire to the red timer wire.
If you only have two wires, one black and one white, at the switch location, then you cannot use this style timer , as it needs a neutral. You should return this timer and get one that does not require a neutral connection.

So you got the timer to work. Is it still working or are you still having problems with it.

SOURCE: I am replacing an in-wall timer switch that

The original timer either was a mechanical wind-up clock or it used a "power stealing" circuit to keep itself powered while it was turned on. The new timer doesn't have this feature. While the light bulb is off, it can run on a small amount of power drawn through the light bulb, but when it turns on the bulb, there is not enough voltage left to keep the switch electronics powered, so when its power supply capacitor runs out of charge, it can't keep the bulb turned on. It probably also forgets its settings.

The only (safe) way to use this model is to bring in a neutral wire. The timer should be connected as follows:

Black: connect to house black from panel (always live when breaker is on).
Red: connect to house black from light fixture.
White: connect to house neutral (white).
Green: connect to house ground (bare copper or green).

If the wires in the box come from one of the porch lights through a conduit (this seems likely; I don't think there are any other legal methods that would leave out the white wire), then it should not be too difficult to add the white wire. Tape a pull string to one end of the wires and pull them out of the conduit at the other end. Bundle a 14 gauge white wire with old wires (tape it to the pull string) and mark the black wire that goes to the light bulbs at each end so you know which one to connect to the red timer wire. Put some wire pulling lubricant on the wire bundle (it will probably pull a lot harder with the extra wire) and pull it all back into the conduit using the pull string.

Note 1: It's tempting to just push the white wire in with the others remaining in place, but it will probably jam when it runs into a place where the others twist around each other, most likely at an elbow in the conduit. That might damage the insulation of the other wires.

Note 2: 14 gauge is the typical size for a residential light circuit. Use the same size that's in there now, and be sure it is a type UL listed for residential power wiring. Look for the fine print on the original wire; you should be OK if you match that. If more than half of the conduit cross-section will be filled with wire when you add the neutral, consult a licensed electrician to be sure you won't have a problem with crowded wires overheating.

Note 3: An alternative is to use the original wires to pull in a 14-3 cable (black, red, white and ground), provided the conduit elbows have a large enough radius to let it go through. However, the jacket on this cable has considerably more friction than the insulation on wires typically run through conduits.

What happened to the original timer? Maybe we can figure out how to fix it more easily than rewiring the box. I know there is at least one two-wire electronic timer on the market, but I'll have to go over to my church and look up the brand and model. Check back after 7:30 pm CST Oct. 13, 2010.

Testimonial: "The white was tucked in the back of the box and painted over so I didn't see it. By connecting as you suggested it woks just super. Thanks"

SOURCE: yes i have an intermatic timer for my outside

If you have a battery-operated Intermatic timer, then it is the ST01C or EJ500.
The advantage of the battery is simple wiring when you replace a light switch.

Both of these timers have troubleshooting in their manuals.
Both timers come with a 1 year warranty.

I have tested the wiring, operation and programming of the Intermatic timers and many other in-wall timers.
If the display does not light up on ST01C or EJ500, then the battery is the only reason.
If the battery is not working, then the timer is broken.
You might try cleaning the battery terminals and connectors located inside the pull-out tray.


These small electrical devices do not have repair parts.
When the timer goes bad, you buy a replacement timer.

You can buy another Intermatic battery-operated timer and keep the simple wiring:

You can also buy Aube T-1034 rechargeable-battery-operated timer.
The T-1034 is strictly sunrise-sunset.
The T-1070 is sunrise-sunset -and/or- multi-day programs

The page below explains the Aube

The links below sell the Aube

T-1034 and T-1070 wiring is slightly different than Intermatic, and you can add a comment and I will help you with any wiring question.

I have some nobo e4eu electric panel heaters with 7 day programmable timers,does anyone know where i can get instructions on how to replace and swap over for a new one?

There are not even photographs of the product online...
That tells me that nobo might be using generic timers made by various manufacturers.
And they might not use the same timer one year to the next... preferring to sell whatever they can buy with lowest price.

A lot of companies re-brand generic products and sell them under their brand name, and folks assume the company made the product.. and the company has manuals... but they don't manufacture anything... they just sell stuff.
First Alert, Timex, Kingshield, Stanley, ... are examples... I suggest not buying products from companies that do not post manuals

maybe you can find a manual by doing a google image search for timers, heater timers, or Nobo ... and seeing if you can find similar timer.

Nobo timer manual below is also sold under Sunlight and Timex brands.

Nobo Heater - Power not constant

You do know that these kinds of heaters "cycle".?? They turn on and off, as a control regulator (thermostat) tells them to. You should have an adjustment that will control how frequently it cycles on and off... You should also have some kind of switch that shuts the heater down if it gets tipped over. However, I tend to assume you know most of this.. If it was simply "cycling", though, I'd think that there would still be some light on full-time to show it really was plugged in and working... So, if I had to bet my money, I'd bet that there's some built in safety switch inside that heats up and kicks the whole thing off quite soon after you start it going. I'd guess that by unplugging it, it eventually resets itself so that you can try it all over again. It could be one of those cases where it might be easier and cheaper to junk it and buy a new one.

Here it is directly from the instructions.
Connect one of the two wires from the wall to the black wire on the timer.
