15-Amp Heavy Duty Astro In-Wall Digital Timer is rated 4.5 out of 5 by 94.

Rated a 4 because of this and the fact that it operates by a CR2 battery which is supposed to last 2 years. Put a sticker inside the door cover so you can remember when to change it. Works as should with LED bulb.

Internmatic ST01 Timer was easy to install and met the requirement of not requiring a neutral. Programming was easy if you read and follow the instructions. There are YouTube videos demonstrating programming as well. I configured the Timer to operate in a Dawn to Dusk mode setting the Sunrise and Sunset times using Daylight Savings Time. The timer is working perfectly. The only issue is that the cover door is only held on by two small tips. This is a potential breaking point because of the tip size especially if you are not careful when you open the door. I do recommend this timer.

Rated 4 out of 5 by from Replacement for 20 yr. old timer After a month of use, I love the astro feature! Here are a few things I learned. 1. It does not adjust daily. My astro feature changes about once a week in September. 2.The dawn and dusk times can be adjusted. Mine is set to go on about 15 minutes before dusk and go off 15 minutes after dawn. 3. It is difficult to hold a flashlight to see display, press buttons, and read directions or watch video all at the same time. Use a headlamp or get someone to help. 4.Compared to my old Intermatic Model SS7C, the click when it turns on is very noticeable. Overall, I am pleased with this timer. It is so convenient to set it and let the timer do the work.

We have used Intermatic timers for many years but this time we are very disappointed. Installation took some work since the device is larger than the Intermatic unit we were replacing. The instructions that came with the timer were incorrect. After several attempts to use the instructions and watching the video, the timer would not come on at dusk. It did shut off at a set time. We called customer support and they told us they are working on correcting the written instructions. We walked through the programming. The timer now comes on at dusk but will not shut off at set time. We have to manually turn timer off for the next 3 days since customer service is closed for the holiday. The support tech that we talked to was very nice and knowledgeable but we do not want to have to make a phone call anytime we need to re - program the timer.

Advertised capability of the timer sounds good, but the user guide does not match the timer. The programming of the timer is archaic and does not work the way the instructions say. Not being able to properly program the timer makes it not very useful. I am usually pretty good at understanding the technology of this sort of thing, but this timer simply does not program the way it should. It does not have to be like this, it should be simple. Too bad.

My experience: As suggested by another reviewer-Install the battery before installation! I had to go through programming the timer a couple of times before I got it to function. Be patient. The instructions are a little confusing. Also, this timer takes up quite a bit of space in the electrical box and was difficult to get all the wires tucked. I am going to need an oversized switch plate. If there are 2 black wires on the old switch, you must find out which one is hot by using a non-contact voltage detector. Mark that wire with tape and then TURN OFF THE BREAKER TO THAT SWITCH. The "HOT" black wire connects to the black wire on the timer. The other black wire connects to the blue wire on the timer. If no white wire, cap off the red wire on the timer. If there is a white (neutral wire) connect it to the red wire of the timer. Connect green ground to green wire on the timer. Hope this helps.

Rated 5 out of 5 by from Outstanding Timer The ST01 from any standpoint, is an outstanding product. It appears to be well made, and in my installation, box size was limited. The ground and red wires were not needed, so I clipped them off. The design of the program is excellent. Once the user understands the basic features, and what needs to be accomplished, the procedure goes smoothly. The user needs to know additional things not covered in the documentation. First, the SETUP and PGM steps are independent of one another. Namely, the SETUP may be modified, without the need to go thru the PGM steps and vice versa. When the battery is low, BATT will be displayed on the screen. It would be ideal if future models of ST01 displayed a red light or some other very visible indication that the battery is low. The 3 units that were installed are operating as described and designed. I’m delighted, particularly since Intermatic ST01 supports my LED light bulbs.

It is very easy to install and the guide was simple to understand. Took me all of 10 minutes, beginning to end. Just be careful with the battery cover, mine took a little bit of force to open. Had to be gentle but firm to avoid breaking any of the plastic. Great timer so far.
