Tools and Hardware Reviews of Intermatic ST01C White Self Adjusting Wall Switch Timer

Customer Review: Very pleased with the two that I am using
Summary: 5 Stars

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.

Customer Review: Cool Switch
Summary: 5 Stars

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.

Customer Review: Works good, and will power CFL
Summary: 4 Stars

I'm not an electrician by any means but was only replacing a single pole switch. I had to do some research and basically stumbled on the fact that most of these types won't work with CFL bulbs, which we use on our porch lights and was the use for this purchase. In reading the directions, for novices like myself, it wasn't real clear about connecting not using the white wires (I think common), only the black ones (I think hot). Also, although I'm an IT professional and so am used to programming, the small display and somewhat unusual approach took a few tries to get reliably speedy at it. Once one goes through it though all is well. This is why the 4 star rating only.

Customer Review: Work's like a Charm!!
Summary: 5 Stars

I have just had a swimming pool installed, and needed a timer to run the pump. Instead of putting in one of the large gray box style, I happened on this one which fits right in the same box as the original switch. One word of caution the switch is rather deep, so make sure you have an extention ring, or not many wiring connections in the same box. The pump is 240vac and the switch has no problem. The buttons are a little small for large fingers, and you'll need the instructions with you to program it. Even the pool contractor thought it was a great idea and may start offering them to new customers.
