Ralph:
The red goes to 12-16VAC. The black goes to COM. The green wire controls the light sequence and is usually connected to a sensor. You can only use Z-Stuff sensors (1011, 1070, 1075) for this signal (I think it is a voltage thing). Dennis can tell you the precise wire connections.
Request - would you please post photo of both sides of the base and the bottom. I have a feeling this is not a Z-Stuff product.
Dennis usually uses white and yellow wires not green.
