I'm setting an irrigation controller and I need a 24V AC source to switch the irrigation solenoids.
Since I have 220V AC, I asked the electrical store for a 220VAC to 24VAC transformer and they gave me this one, but I'm unsure how to wire it. Which wires should connect to live and neutral on the 220VAC supply and which are live and neutral on the 24V output? My best guess is that the black wire is used on both the input and output as a common neutral, but don't want to chance it.
Any advice appreciated!
