Intermatic EI210W Programmable Electronic Auto-Off Timer

EE: I bought three of these and that worked fine for six years. Now they are failing and need to replace. I guess I got my money’s worth with a six year life.

MyRealReview: I just installed this in my bathroom to control my exhaust fan, and I am happy to report that it works perfectly. I was surprised to learn that some timers do not properly operate exhaust fans, so I got this one because it states that it is specifically for use in exhaust fans.

Install was straight forward and took about 30 minutes. Most of the time was spent getting everything back inside the conduit box. I just barely made it work. Like most specialty switches, this one is rather bulky. My house has very old, small metal boxes. If you have the same problem and can't get everything to fit, you have a couple options. You can get an extender plate that makes the faceplate stick out a little from the wall or you can remove the old box, cut the hole a little bigger, and install a larger remodeler conduit box. This would be a reasonable project for a competent DIY'er, but, as with everything electrical, if in doubt, call a pro.

Anyway, I am a happy camper. I can vent my bathroom without forgetting to turn off the fan and wasting heat. I own a couple of apartments, and I will be installing these in them also.

Jesse: Works great, easy to use. I have only had it in place for about a month but have had no issues so far. This replaced a mechanical timer switch that would get stuck at certain points on its rotation, so this electronic option is a much better fit for my needs.

Installation is slightly more difficult than some standard switches. This switch (because it is electronic in nature) requires the neutral (usually the white wire) to be connected along with the hot wire (usually the black wire) where simple flip switches generally just interrupt the hot wire. This switch also requires you to know which wire leads from the source (your power box) and which wire goes to the load (the device that you want switched) which in my case was a ceiling fan. None of this stuff is hard to figure out, but if you are an electrical novice you might want to have some backup from someone who understands AC house wiring and can help you figure out what goes where (this is really simple for anyone who has home AC wiring experience).

R. C.: I have used this exact timer in my home for a bathroom fan for 3 years now and it has worked flawlessly. We had installed remote fans (as in far from the bathroom) and the fans were always being left on because they can not be heard. This timer solved that problem. I decided to upgrade our other bathroom and could not find the same timer in the big box stores nearby so I ordered through Amazon. The only thing that a person should be aware of is that the timer is not a small unit and it does take up some room in the wall switch box. So take a peek in your switch box first and if it is already crammed full of wires or is a shallow type box then be aware that it may be a very tight fit.
