- The sensor has 3 wires: blue/white/orange. Hunter's manual says blue/white wires are used for "normally-closed" sensors and blue/orange for "normally-opened" ones. Which wires should I connect to HD-12 and where do I connected them?
- This knowledge-base article (link) shows a diagram where the 2 wires from a rain sensor are connected to the right side of HD-12 for "software control over the sensor". The HD-12 that I bought doesn't have any connectors on the right hand side matching what's shown in the diagram. How do I connect?
- What does "software control over the sensor" mean? What "software" and what "control"?
