Long time ago I bought an Opensprinkler OS3.0 DC-powered to control a few 12VDC valves. But i would like to control 24VAC valves with it. Is it possible? I am confused. Thank you so much!

The OpenSprinkler product page explains this explicitly, and it’s also in the FAQ. Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
