Hahn,

Which actuator do you have? I have a EVR2 K - have you found a double circuit relay for it, or another way to control the actuator?

A Aquarium Systems 'Natural Wave' wave timer works great... all you have to do is switch the power between the two lnputs when you want it to switch.

What do they need for control?

Don

The EVR actuator has 2 hot inputs, and shares a common neutral.
Post 3 - AC HOT CCW (Counter Clock Wise)
Post 4 - AC HOT CW (Clock Wise)

Yes - this will work great if you plan on running a surge/wave maker/(OM) type device.

I should've elaborated a little more - I'm using it to automate water changes, and need a relay that has 2 circuits, powered by same if possible, and by default 1 circuit is completed. I ordered a SPDT relay tonight - should have it tuesday.

Changed my mind - I'm selling my Actuator & ball valve combo.
