White, Heavy Duty In Wall Timer With Astronomic Feature, Can Be Used With 4 Separate Programming Options: Same Settings Monday Through Friday, Saturday & Sunday, All Days Of The Week Or Individual Daily Settings, Battery Backup, Manual Override, LCD Digital Clock Readout, Up To 6 On/Off Settings Per 7-Day Period.

Great little timer; work well with compact flourescent bulbs.

I purchased the ST01C timer to control a post light with 4 13W compact flourescent bulbs and 2 exterior wall lights, each with 3 7W compact flourescent bulbs.

In short, this timer works well and does not cause flickering of the bulbs because a relay completes and opens the load under control of the many programs that can be entered into this unit. It's really amazing how much Intermatic has crammed into something that fits in a standard receptable box.

I have nothing to add to the many positive comments already written here by others, however I would add that it is easier to read the display when programming if a small penlight is shined head-on; the "am" and "pm" indicators, in particular, are very difficult to read because they are so small. This is a minor issue, as far as I am concerned, compared to the many conveniences this timer presents.

Cool Switch

Very easy to install. Very easy to program. I need to do a little tweaking, but this was an awesome addition for someone who comes home at all different hours and travels fairly often.

Very pleased with the two that I am using

I have been using an InterMatic ST01C for over two years now and have not experienced any of the problems described by some of the other reviewers. In fact, I like the first timer so much that I purchased and installed a second unit in another circuit.

I have found the clock to be reasonably accurate and that it requires only minor adjustments of no more than two minutes after four or five months of use. The adjustments are so minor and so infrequent that this just has not been a problem worth noting. DST adjustment is automatic and has been updated for the newer extended dates set by Congress. I also found that after I manually adjusted the dusk and dawn times for my exact location that automatic corrections for changes in sunset and sunrise were made by unit without problem.

Programming of this timer is not difficult either. The unit comes with a set of quick programming instructions which are easy to follow and very straight forward. It is amazing how flexible this small device is and how many different programming options it will accommodate. Once programmed, it can then be set to automatically control lights or devices or the "manual" mode can be used to discontinue the programmed events. You then control the switch (off and on) of the timer by pushing on the outside cover. There is also a "random" mode that will vary the programmed setting by as much as twenty minutes to give a more occupied look to lights in your house when you are away.

Installation of the timer is not difficult at all if you are using it in a circuit where one switch controls lights or devices. If you want to install it in a circuit where two or more switches control lights or devices the installation becomes more of a challenge. I installed my most recent ST01C in a circuit where three switches controlled outside lights. After I changed the house wiring around and changed out a four way switch to a three way as outlined in the timer instructions, everything worked perfectly. The timer became one of the switches and the other two switches worked as before.

The ST01C can be used with various types of lights and devices. It will control incandescent as well as the new energy saving compact fluorescent bulbs. It will also control small motors such as the pump on a garden fountain.

Because this timer is compact enough to fit in an existing wall switch box, the display is rather small and can be difficult to see. For that reason, I did all of my programming before mounting the timer in the wall box.

The ST01C clock, programming and relay are powered by a small Panasonic CR2 battery. Replacement batteries are available at most of the chain drug stores in the camera department. I replaced the battery in my older timer after about a year and a half but think it would have lasted longer.

I believe the ST01C to be a good value for the money. If mine breaks after a couple years of use, for $30+ I would quickly go out and buy another. If you have more questions about the ST01C, Intermatic has a copy of the owner's instructions and the quick programming instructions on their Web site in pdf format. I recommend this timer and give it a hardy five stars.
