I have a new Solenoid for my propane system. To my surprise it has 3 wires... seems like 2 would be normal?? (cant remember havent installed one in years.) The very small print literature included in the box doesnt show a wiring diagram... is mostly liability verbiage etc... How do I wire this thing? I guess I can just wire up 2 wires and keep trying at random....
According to the Asco FAQ: ASCO Valve - FAQ Product Questions Q: How do you wire a Red-Hat II Valve (3 wire coil)? A: All ASCO AC/DC coils are suitable for continuous duty except where otherwise noted and are single phase.
RedHat II coils have 3 wires - 2 wires of the same color (i.e., red or yellow) and 1 wire green with a yellow stripe which is an external ground wire. Since ASCO coils are not polarity sensitive, connect the 2 wires of the same color to the positive and negative power supply, the green/yellow stripe wire to ground.
For three-phase systems, the 2 wires of the same color can be connected to any of the three phases.
