Product Description

Product Description

7 Day - 24/277 volt - 20 amp - White - Heavy Duty - Digital - In-Wall - Astro | Intermatic Timer

From the Manufacturer

The EI600W is an easy to install and program timer that is perfect for energy savings, security, and convenience. Provides up to 40 ON/OFF operations per week which can be used for 24-hour or 7-day load control for all voltages 120-277 VAC up to 15 Amps. The astronomic feature provides sunset ON and sunrise OFF settings and the auto daylight savings adjustment means you can "set-it and forget-it". The independent 7-day programming provides complete flexibility for applications where load switching differs each day of the week. Astronomic programming can be combined with independent programs to provide a sunset ON and timed OFF program. Provides up to three years of time keeping without AC power. User program selections are stored in non-volatile memory. A low battery indicator appears in the display when the battery requires replacement. The timer has an isolated single pole single throw switch which allows the timer to switch any load type.. A "3 wire" design allows the timer to replace, or be used as a single-pole or 3-way (multi-way) switch. White color.

Customer Reviews

Very flexible, works great.
We got one exchanged under warranty (would not operate after 3 months), but the replacement died within 6 months as well.

Super easy install and programming was not difficult at all if you read the instructions.

Short version: I had to reprogram Again and Again and Again... Buy Aube instead.

I bought this timer for several rental buildings because I thought having a light timer that would automatically adjust entry lights with the Seasons would be great. Intermatic seemed to be the dominant brand you can get at hardware stores and such.

BUT ALL OF THE TIMERS FAILED. Every single one would forget its programming. Not a battery problem. They would just forget.
Programming them is no fun. The instructions are iffy (and the print is smudgy and microscopic). It's no fun at all to have to over an reprogram one of these pieces of junk every few months (or weeks - or sometimes days).

I have now ripped them all out and replaced them with Aube by Honeywell (very similar product available on Amazon. The Aube that automatically adjusts for the seasons is called "Solar." I have one Aube that's been running without a problem for two years.

You would think since Intermatic specializes in timers they would've managed to make this product work.

It has other faults. A strange battery. A hard to read display. Poorly written instructions.
But the Intermatic timers (including the regular 7 day electronic timers) I have purchased simply do not work.

UPDATE: My handyman just bought this Intermatic timer without asking me and installed it. It was DOA.
It would program and everything seemed to function --- except the switch was non functioning, so the lights wouldn't come on.
Ugh. Check out Aube by Honeywell timers . I'm ordering another one of those to replace this one.

First, the bad:
Yes; this timer has very tiny buttons that may be hard to press individually or see. Do yourself a favor, and have enough light handy and wear your glasses. You'll have no problem seeing the buttons. As for pressing them, get a small screwdriver, toothpick, or dull pencil to press the buttons. The ability to use tools is what separates us from the animals. Let's not forget that! :) It is also somewhat difficult to program, but I've found that many devises that give so much flexibility can be a little more difficult to understand. Keep the instructions handy if you think you'll forget the steps to program the timer. My unit also does lose a few minutes every few months or so. Not a big deal for me though...

Now for the good:
I've had this device installed and operating an outside light for about four years now. Once programmed, it is truly a set-it-and-forget-it kind of device if you want it to be. I have mine programmed to come on at dusk every day, and turn off at 12:30am during the week and 3:30am on weekends. I could also have a different program for each day of the week. Just in case I turn it on manually, I also have it scheduled to do a turn-off every morning at dawn so I don't have the light on all day long. This switch truly does everything I could ask of it. Once you understand the programming, it's rather easy to operate as well. The random feature is also nice if you want to make it appear like someone is actually home turning the lights on and off.

This thing works exactly as it should. For all of the folks that complain that the buttons are too small, I really don't see any alternative. We're replacing a light switch here, which really limits the amount of space we have to play with! I find it quite impressive how we're able to get such technology with useful features into such a small package, so I can forgive the small size of the buttons.

First of all let me tell you my expertise in this area. I've been an electrical contractor for 31 years in the midwest and have installed a lot of these timers in customers homes and in my home. The ones in my house I installed a couple of years ago and except for a problem with one of the units right away I've had no issues. The one problem I had, one of the timers was eating batteries at a rate of 1 every other day. I quickly pulled the unit out and had the supply house replace it and have had no problems since. I just recently tried to install two of these at a customers house and both were broken from the get go. I had the same problem with both of them. Neither one would allow me to get into the programing mode. I checked the batteries and they were fine. Not sure what the problem was but I ended up having to buy a couple of GE wall timers from Home Depot and returned the Intermatic ones to the supply house. I will not use or recommend Intermatic wall timers anymore. The GE's that I installed are working properly but do not have the ability to follow sunset and sunrise times and set themselves for daylight savings time. Another plus for the Intermatic's was that it didn't require a neutral wire to operate but the GE does. In most cases this isn't a problem unless all you have is a switch leg where your going to install the timer. The Intermatic is solely dependent on the battery for everything, on the other hand the GE uses line voltage entirely and but does have a small battery to retain time and programed settings. I've had over the years had the Intermatics fail after only a few months but after this last incident I am crossing the Intermatics off my list!
