Answer: 
Essentially, the timer will go into ON mode when you need the lights to be on and OFF mode when you don't need them on.
You would program the specific time yourself to get the correct time cycle(s).

Does this unit fit in a duplex sized electrical box? Other units were either too deep for the box, or too fat fat to allow other switches in the box

Answer: 
IMine is installed in a duplex box. It isn't too fat but you do have to move the wires around a little to sit them both in there.

Answer: 
Yes the unit will fit in a 2" (or deeper) 2-gang switch box or duplex outlet box. The timer is wider than a normal switch but is designed to fit next to an existing switch or another timer.

15-Amp In-Wall Heavy Duty Astronomic Digital Timer is rated 4.6 out of 5 by 47.
Rated 5 out of 5 by from Doesn't Need AC Power to Operate I'd used a prior version of this timer which was fatally flawed - the logic connections internally would degrade over time and it would fail. This re-design looks almost perfect. It uses a very long life lithium battery and the switch mechanism uses a high quality micro-switch and a magnetically latching solenoid - low power, reliable and rugged. The build and design look good and it seems to keep good time - the operation is completely independent of input power - one of mine is used off-grid completely. The application for three-way switching is different from traditional mechanical switches, but good for most all cases, except very long runs or more than two switches. If you have these cases, look at the details from Intermatic before committing.

Rated 4 out of 5 by from Works as described Easy to install with usual electrical tools. Very large and requires lots of space in junction box. Recommend watching you tube video. Programming is very confusing, but doable when programming done before installing as recommended. Changing a program once it's in the wall, using its tiny screen to follow what you're trying to do is very challenging. I'd rate a 5 on all counts if it weren't so complicated to program. Can order through manufacturer's website for almost exactly twice the price paid at Home Depot, and they charge for shipping.

Rated 1 out of 5 by from Recieved old/outdated product. I ordered 3 of these timers from Home Depot, I had been wanting to purchase the 3 timers for awhile but had to wait until I could fit the purchase into my monthly budget due to being on Social Security disability. I was disappointed after they arrived due to the fact that the manufacture dates on the timer boxes were listed as being made in 2009. My 1st clue that the timers were old was the fact that the timer boxes or included literature didn't mention that they were LED compatible. The lithium battery that comes with each timer has a 2 year expiration date, and I received these timers 8 years after they were made. I contacted the manufacturer and they confirmed the timers were made 8 years ago, they blamed Home Depot for letting them sit on their distribution center shelves too long. The manufacturer representative did inform me that the timers I received were LED compatible even though it didn't indicate that they were with the outdated packaging and included literature. They understood my concern over the 8 year old lithium batteries and why I would be returning them to Home Depot. When I contacted the Home Depot customer service department for online orders, they stated that the 3 timers were shipped directly from the manufacturer. I was informed that I could ship them back or return them to my local store for a refund. The customer service representative didn't even apologize to me for receiving old/outdated merchandise and they didn't even offer to give me any discounts when I was ready to reorder 3 new timers. They only suggested that when I was ready to reorder, that I order over the phone so the next customer service representative could add notes to the order to make sure I would receive brand new/recently manufactured timers. I returned the timers to my local Home Depot store, I hope to eventually purchase 3 new timers at a later date.

Rated 4 out of 5 by from Digital timer Installation is simple and easy and takes no more than 10-15 minutes but programming sucks. The instructions are difficult and somewhat misleading. If you wish to custom program the timer the 'ON" time is Zone 1 and 'OFF' time is Zone 2. The technical support was excellent and able to guide me thru the programming process in 2 minutes. Overall the product is good.

Rated 5 out of 5 by from Great product! Does exactly what we wanted it to do! Only hard part of installation was programming on and off times at first. Once you realize that program #1 is the on time and program #2 is the off time it is easy!

Rated 5 out of 5 by from 15-Amp In-Wall Heavy Duty Astronomic Digital Timer My 8-year old Intermatic unit bit the dust and I replaced it with this one. The old one did not self adjust for daylight-savings-time but this one does. Nice!!
