I want a timer that turn's on for 12 hours then off for 12, I'm assuming this can do that? don't want it to turn on and off every 15 minutes.

this definitely does that. It gives you adjustment down to 15 minutes. Others will do what you want, but this just gives you more flexibility down to every 15 minutes as opposed to half hour or hour intervals. I use this on my aguaponics setup and it runs for fifteen minutes on and forty five minutes off. You control the adjustment in fifteen minute intervals. This is the most amount of adjustment that i have seen from a timer that isn't digitally controlled.

You can have it turn on as much as 24 hours hours a day to as little as 15 minutes a day and in between. So yes, 12 hours on and 12 hours off it possible.

you can program it to stay on as long or as short as you wish with about 15 minute resolution.

You can set the timer to stay on or off as long as you want. A 12 hour block is no problem.

you control the length of the timing by setting multiple 15 minutes segments. you can set the time for whatever lengths you like

It will do exactly that--with a simple setting of 2 plastic push pin things that come with it.

Touch the button on the right and the timer will go off. That button turns it on and off.

Mine has been on for about a month straight, and a timer is no problem. It's the same as if you were to switch the power on and off yourself.

I set mine on "timer" and then switched it to "on". It worked for a while but about half of my timers wouldn't hold the actual time so they wouldn't come on at the right time.

Yes I able to set the timer to go on at 7PM and turn off at 11PM for 7 days a week without much difficulty. Did have to follow the direction and do it several times but is working well. I like it!!!!!

I let mine go for 12 hrs.the unit does not have a timer on it,you must add a timer or track time when you start.

Like another customer indicated don't waste your money. This is not a good product. I had the same issue with the timer not shutting off. I complained to the manufacturer and the two replacements they sent me had the same issue. The answer to your question is that yes you can set it to any amount of time you want but it just might not shut off when you want. btw orbit does make some good product, just not this one.

I haven't tested it, but I dont think the timer works unless you turn past 10 and then back to the time you want

No, this is not a programmable or repeating timer. It only counts down to shutoff based on the duration you choose each time you turn it on. For on and off settings repeated daily, look for the simple round model with a perimeter of pegs representing half-hours.

I'm not sure, as we do not use ours on a timer. Sorry if this isn't helpful.

I have been setting my timer to 9 hours, and that seems to work well. You can control the timing. If you think 9 hours is too long, set for less.

You can set the timer for up to 180 min. I believe if shuts off after 180 min if you do not set the timer.

When you use the timer it turns off automatically. You probably used the "on" position not the timer.

I am sure the timer allows you to manually override the timed settings. (Most timers do allow this.) The On/Off buttons provide this capability.

No, not really. You can only set it to go off a certain number of hours and minutes from the time that you set it. If it was the same number of hours everyday from when you were setting it to when you wanted it to go off you can just re-start easily to count down again once it has gone off.

You have to preset times you want something to turn on or off.Won't turn on automatically in 24 hours if someone shuts off.

If the unit is off you can push the timer button and then select how many hours until it will turn back on. You can choose between 1-12 hours. If the unit is on you can also push the timer button and select between 1-12 hours before it will shut off.
