Question: Does this switch come with a jumper so it can be used for a three way switch application?
Document: I have used several before and bought a replacement. They only come in white but would have preferred a beige. They are easy to program when you read and double read the instructions. They work well and allow multiple programs or manual on/off.
It is complicated to program. There are six function buttons, the abbreviated instructions are difficult follow. Because of the limited size of screen. letters are very hard to read. I had to program three times before I got it right.On positive side once you understand and follow instruction correctly it can be used to do everything what one wants from a little timer of this size.
Actually, I programmed it to come on 15 min after sunset. It's been working for a few months now and occasionally I check on it. It's following the season. I don't have to worry about it and perhaps only need to replace the light bulbs or the timer when it dies. Hopefully not too soon.The only reason for 4-star is that the display is barely useful once it's installed. The time display does not need to be so big and the status displays are way too small.
This item works fine, but be aware this version now uses an electronic on/off switch versus the older versions that used a mechanical relay. As such this does not work properly with CFL bulbs as they flash versus running smoothly with the older version.
Easy to install and works well. If you are doing a 3 way switch make sure you are working on two switches for the same light &#128572;
I have several Intermatic wall switches in my house, one of which handles a two way setup. The type switch in use is apparently no longer available. I bought the EJ500 as a backup.
The timer works  well, I used it for my porch light.l. It's nice because it adjusts to sunset and sunup which is the setting I used; no more adjusting every couple of weeks. The programming was a little tough but considering what it has to do I can understand that. The only thing that could have been better explained by the Mfg. was the switch on top (hence only four stars).
I have had these for a few months now. They are really very easy to replace from existing switch plates. I put one in for our front porch lights and one for lights in the drive way. Really convenient as you don't have to switch on or off. Truly set it and forget it!
I've only had this switch/timer a couple of weeks. It's way better than the previous analog version I had. But the setup is more complicated than I think it needs to be. I compare it to sprinkler timers, I had easy to use and complicated to use, but they all do the exact same thing.
I plan to replace three switches but have only replaced one yet. The switch works great with regards to working on time, quietness, design, ease of programming, and manual overrides. However, the CFL bulb flickers...or rather blinks. It starts off flickering at a high frequency (1 per 3 secs) but this tends to ease up a little in a couple of hours (1 per 15 secs).
Answer: yes
