No power needed. Mechanical timer turns gas off when the time you selected is reached.

It uses a spring loaded valve with what might be called an egg timer. When the timer counts down to zero the valve shuts. There is no external power required.

no power supply. BUT the batteries you put in there last for such a long time, I am, actually, very shocked and pleased!

No, it is just the connector and there was no shut off valve. That would be a nice feature though.

How has it been installed. Mine leaked there until I run the system. There are 3 check valves that open with a screwdriver. Try bleeding them and see if it fixes your problem

Hi Jason, unfortunally I do not know your system - but you should have a look on your valves. The power they need should match to that controller.regards, Torsten

No power is needed for this unit. You only need a water hose to hook up to. .

That didn't work in my case. I went with a 2 way shut off valve (find them in the garden center of your local box hardware store)

Yes, it comes with a power supply. But I do not recommend this product at all. I have had 2 of them and both motherboards have failed within weeks. i had to return both units. I would recommend you look for something else.

The valves have a plug but there is no hole to pump the air. Can anyone please confirm if a hole needs to be created again or did I miss something

Yes this should work for your application. The valve is closed when there is no power. It only opens when power is supplied to the solenoid.

Not sure exactly... but I didn't need to get any additional power supply to make it work... just plugged it in.. and had been working great since purchase.

No power supply. You can purchase one fairly cheap or use an injector. Unit works great hoeever it is powered!

It might work. You'd have to place the control unit about midway between the outlet and the valve. The cable from the power adapter to the control unit is about 5 or 6 feet long.

No it doesn't come with a power supply. The kind you need is really more dependent on other components in your system, usually the video card.

You need a power outlet and you use the toilet shut-off valve for the water source, come with complete instructions.RAK Online Services

Other thing is that the solenoid must be completly tight to be used with the computer. You only turn this maybe 180deg maxs to manually open the valve. If you turn more water start leaking. This is normal.
