Looking for alternating timer.

[dongle69]

I'm looking for a timer that allows for on/off settings every other day.
All I see are timers that allow for day of week settings, but if I wanted to use alternating days I would have to change the timer settings every week.

?

some digital timers allow setting of weekly programs.

Both of these allow you to alternate, or skip, different days. Intermatic ET1725C - 7-Day Electronic Time Switch; has two independent circuits, and is cheaper than the single circuit model ($124):

Thanks, but from what from what I can see, those look like weekly timers.
I need something that I can alternate without having to reset weekly.
In other words, M-W-F-Su-Tu-Th-Sa-M, etc.
The weekly timers only allow for alternating up to one week, M-W-F-Su, then I would have reset the timer to start again for Tu-Th-Sa, then reset again for M-W-F-Su, etc.
I'm also looking for a standard plug timer.
It is just for watering pumps.

SHT-3 Digital time switch can be used for operating controls in real time.
Daily, weekly, monthly, and yearly program in one device.

I've run across some irrigation timers for a gravity drip system I'm making. They operate just like you want, every other day or whatever. Can you get your water/nutes elevated?

He can use a sprinkler timer wired to a relay, with the relay turning the pump(s) on and off.

Thanks y'all. That sht-3 is certainly up to the job but it looks like I would have to program every day in individually. I do like that it can handle seconds as well as minutes. Irrigation/sprinkler timers might be where it's at, and PharmaCan's suggestion of using one with a relay might be the ticket.

How about a repeat cycle timer?

How about a repeat cycle timer?

Which one?
I can't find any that do what I am asking.

Check places like Grainger.

I think your looking for a 48 hour timer... =) http://www.cotswold-dairy.co.uk/PAGEFILES/CLOCK48/CLOCK481.html

something LIKE this? maybe

 

[dongle69]

Thanks micro, I'll poke around there...
Thanks Sn@tcher420, but that is just a standard 7 day timer...
Thanks globel, I think you found the ticket.
Since they say they customize, I may try to get them to do a digital version...
