I am replacing a Honeywell ZD20x14 two-wire, 24v damper in my HVAC system. The damper has an orange wire and a yellow wire. Unfortunately the old damper was removed, so I didn't see how these wires were connected. The old damper was connected to red and green wires coming up from the panel. I don't know if it makes a difference, but should red go to orange or yellow?
