Connecting a Rain Sensor

Connecting a rain sensor to your Rain Dial controller is a straightforward process that enhances your irrigation system’s efficiency. The Rain Dial Plus model is specifically designed to work with a normally-closed rain sensor or rain switch, ensuring that watering schedules are automatically adjusted based on rainfall.

To begin, route the two wires from the rain sensor into the controller cabinet through the valve wire opening. This ensures that the sensor’s connections remain protected from the elements. Once the wires are inside the cabinet, locate the sensor terminals on the controller. You will typically find a jumper wire connected across these terminals, which needs to be removed to accommodate the sensor connection.

After removing the jumper wire, connect each of the sensor wires to the appropriate terminals. It’s important to ensure that the wires are securely fastened to maintain a reliable connection. Once the physical connections are made, refer to the controller’s programming menu to enable the rain sensor feature. This step ensures that the controller recognizes and responds to signals from the sensor.

Finally, test the rain sensor by simulating rainfall or waiting for natural precipitation to occur. Observe the controller’s response to ensure that it is prolonging or cancelling the watering schedule as expected. This verification step is crucial to confirm that the sensor and controller are communicating effectively.

By integrating a rain sensor with your Rain Dial controller, you can optimize water usage and ensure that your lawn or garden receives the right amount of water, even in varying weather conditions.
