I want to build an intermittent mist propagation setup for cuttings on my back porch, and I have a couple questions for the more electrically inclined members. The system I hoped to build would be a reservoir type design versus water being supplied by PVC pipe, using solenoids to control the flow. I was hoping to wire a Galcon 8056S or similar timer straight to a fountain pump. The timer's output is 24 volt AC and the pumps come in a few voltage configurations such as: 12 volt DC, 12 volt AC, or 24 volt DC. I see them even without the transformers included (so I don't have to remove the cord before hand). So, my question is, can I wire a timer with 24 volt AC output to one of these fountain pumps with one of these different voltage inputs? Is it just a matter of wiring a converter between the timer and the pump? I will post pics after the build is complete.

No, running 24 volts to a 12 volt system would burn up the pump. You could build a bridge rectifier to turn 24 volt AC into 12 volt DC.

I would wire in a control relay from the timer. Any 24 VAC relay should be easy to find on the Internet with a set of open contacts. When 24 VAC is applied it closes a relay switch allowing DC power to flow to your pump. Chad

I posted a reply, but quickly deleted it because I didn't like my answer. I thought more about it. I design and install irrigation systems. For a residential system the water is always on. (Positive pressure). For your system, one timer (like a Christmas light timer) would turn on your pump providing the positive pressure. Then your irrigation timer would activate the selinoids. When all of the zones finish, the pump timer would turn off the pump. Simple enough.

My house irrigation system is purely mechanical and does not use solenoids. So that's why I want to do a reservoir setup. Should have said that.

Oh so it's just a 1 zone system. Just use a cheap Christmas light timer. $10-$15 any pump will plug right in.

Guys, there is a power strip you buy that has a built-in timer. I have 3 of them. It's pretty slick! Looks just like a normal power strip. They're only about 20 bucks.http://www.htgsupply.com/Product-8-Outlet-Surge-Protector-w-Built-In-Timer
