Using a Rain Sensor
Any “dry contact interface type” rain sensor can be attached to your Cyber-Rain controller. The rain sensor will provide a double layer of protection against
watering when it is raining. If it senses rain, it will stop all watering regardless of whether the rain has been forecast. Watering will not resume until the rain
sensor is no longer activated and the rain sensor countdown has completed. The rain hold length can be changed by setting the delay until watering resumes.
Follow these steps to properly integrate a rain sensor to your Cyber-Rain controller:
1. Ensure that your rain sensing device is properly mounted in a location where the rainfall is to be measured.
2. There will be two wire leads that extend from the rain sensor device. Make sure that these leads are long enough to reach the controller. Insert each
wire into the included rain sensor harness (see photo of part C in the Package Contents section) and tighten each screw until it clamps down tightly on
the wires. Connect the (+) positive wire to the left side opening in the rain sensor harness and the (-) negative wire to the right side opening (make sure
the screw terminals are facing up). Normally, the red wire goes to (+) positive terminal and the black wire to the (-) negative terminal.
3. Insert the rain sensor harness into the connector located on the bottom of your controller labeled “RAIN” making sure that it is properly aligned. (Note:
This is the 2-wire slot on the LEFT in Pro models.)
