I used this to indicate when my dehumidifier was running. It's in the attic and is almost silent, and the humidistat I use is an unspecified old style. So I ran a common (neutral) ground from the dehumidifier to the humidistat and connected one side to an LED and connected the other side of the LED to the relay wire. Now I can tell it's working by the green glow every time it turns on.
