I need a unit that will leave the valve open all night. Many only allow up to 2 hours. Can this one be programmed to be open for 6-8 hours?

No if I remember right it is only for like three hours. You select how many minutes, it might have been up to 240 minutes. Been all winter haven't messed with it in months and don't have access to it currently. I love the timer though, it has worked great and reliable for me last year. My only quam with it is that it doesn't have a calendar type setup. My watering days are on the even days of the month, so if I select it to water every other day then I have to reset it come the 31st. So as long as the month ends in 28 or 30 I'm great. But otherwise it has helped me tremendously. Good Luck.

I just check mine and the time is fully digital and you can set it run for as many hours as needed! This is a very good and easy to use timer. It's also very easy to program too!

I don't think I would worry about leaving it on overnight. We had it running for 8 hours at a time. The wire that burned out did not cause any problems other than making the unit inoperable.

I had the same problem. The valves close with magnets. You may need to use the program unit to manually open and close it rather than the knobs to get the magnet to close.

not sure, I just turn off the valve, It is easier for me to do that when its raining because my unit is hidden.

I start mine about 10 PM and it will run all night and shuts off around 7 AM. Hope you enjoy yours as much as I do mine.

Long time so far. I am sure it depends on how often you open and close the valve. Standby mine have lasted 6 mo. so far.

Yes, it is possible, just have it normally with 12v applied, then when you want it closed, remove the 12v power. Boom, normally opened. This isn't ideal, as you should just buy a normally opened valve, however if you can't find one, this could work, but may reduce the life of the valve.

The instructions specify that one fill of the plastic cup (1/3 cup water) will last for 1 cycle on the timer thing (where the on and off button is located). If you choose the 9 hr cycle (the very last cycle located all the way on the right side of the on and off switch) if will run all night.

Yes when you look at each control unit you can go to menu and set each side of the bed sep. you can change it from 0 auto shut off to 10 hours.

No, it can be programed to come on at sunset but you have to choose how long it will stay on (2, 4, 6, 8, 10, 12, 14 or 16 hours).

Yes. The operation manual says "The line is programmable to release water up to two times a day on any or all days of the week, for duration ranging from 1 minute to 23 hours and 59 minutes." I have mine connected to a freeze free spigot and leave the spigot open all the time allowing the Claber to turn on and off as necessary. It works very well, and 1 9v battery lasts all season. Only caution is if you live in a cold climate, make sure to disconnect the Claber and take it indoors before the first freeze.

Not 100% sure, but from my experience this is just a 24 hour timer-not programmable the way you require- I recommend a different one for that function.

I sat at my desk in the house and programed it. I have trouble seeing it where it is outside in the pump house. I can then just change the duration times as I need (still a bit hard to see). if it helps the time that first displays is always midnight

There is a timer of sorts on this unit. You can adjust how many hours you would like the unit to run (only 1 hour increments). So instead of setting a timer for 3:30 - 5:30, you would turn it on at 3:30 and set for 2 hours. Hope that makes it clear.

Sally, Yes. My reason is this: If you are replacing a old timer with new, the component parts down stream --the electronically-operated valves -- don't care what kind of timer you are using. For all "they" care, it could be a timer from another manufacturer. You are good to go! The only semi-difficult part of installation is getting the wiring correct when you make the transfer. I took a picture to use as a guide. Also, change the internal 9 volt back-up battery once a year. That will keep your programmed settings in memory if there's a power failure. Cheers, Jerry

You'd either need four of these or two of the double sided ones. Given the right number of dispensers, yes it would work for your needs. You could set them at 9 pm the previous night you'd set one for 9 hours (6 am), one for 13 hours (10 am), one for 17 hours (2 pm), and one for 21 hours (6 pm). Mine generally opens within a 15 minute window of the number of hours I set it for (15 before or 15 after). That's just a product of the way the timer is designed. It's no biggie in my household.

Yes, it has a timer to run up to one hour. However, you must be awake to release the pressure when it shuts off. That is not automatic.
