Connecting a Rain Sensor
Connecting a rain sensor to the Rain Bird SST-900i allows the system to automatically suspend watering when it rains. Remove the jumper wire and connect the rain sensor wires to the designated terminals for optimal performance.
Removing the Jumper Wire
Before connecting a rain sensor to your Rain Bird SST-900i irrigation timer, it’s crucial to correctly remove the jumper wire. This wire acts as a default connection, allowing the timer to operate without a rain sensor. To install a rain sensor effectively, this connection must be broken.
First, locate the wiring bay at the bottom of the SST-900i unit. You may need to remove a cover to access the terminal block. Look for the terminals specifically marked “RAIN SENSOR.” These terminals will have a small yellow jumper wire connecting them.
Using a small pair of pliers or your fingers, carefully detach the jumper wire from both terminals. Ensure you pull the wire straight out to avoid bending or damaging the terminals. Store the jumper wire in a safe place. Do not discard it, as you may need to reconnect it if you remove the rain sensor in the future.
Removing the jumper wire signals to the timer that a rain sensor is now in use. Without this step, the timer will continue to operate according to its programmed schedule, disregarding any input from the rain sensor. Remember, the system needs this step to function correctly.
Connecting the Rain Sensor Wires
After successfully removing the jumper wire from the “RAIN SENSOR” terminals on your Rain Bird SST-900i, the next step is to connect the rain sensor wires. This connection allows the rain sensor to communicate with the timer, automatically suspending irrigation when rainfall is detected.
Take the two wires from your rain sensor. It generally doesn’t matter which wire connects to which terminal, as the connection is simply a closed or open circuit. Insert one wire into one of the “RAIN SENSOR” terminals. Use a small screwdriver to tighten the terminal screw, securing the wire in place.
Repeat this process with the second wire, inserting it into the remaining “RAIN SENSOR” terminal and tightening the screw. Ensure both wires are firmly connected and cannot be easily pulled out. A loose connection can cause intermittent or complete failure of the rain sensor function.
Once the wires are securely connected, gently tug on each wire to confirm they are properly fastened. Replace the wiring bay cover, if applicable. Your Rain Bird SST-900i is now configured to use the rain sensor to intelligently manage your irrigation schedule, conserving water and protecting your landscape. Test the sensor.
Seasonal Adjustments
The Rain Bird SST-900i offers a convenient feature for seasonal adjustments, allowing you to easily modify watering durations based on the changing needs of your landscape throughout the year. This one-touch adjustment simplifies the process of increasing or decreasing watering times without needing to reprogram each individual zone.
During hotter, drier months, plants typically require more water. The seasonal adjustment feature allows you to increase the watering duration by a percentage. For instance, setting the adjustment to 120% will increase all programmed watering times by 20%. This ensures your plants receive adequate hydration during peak seasons.
Conversely, in rainy or cooler periods, reducing watering times is crucial to prevent overwatering and potential root rot. By setting the seasonal adjustment to a value below 100%, you can decrease the watering duration proportionally. A setting of 80% would reduce all programmed watering times by 20%. Regularly adjusting can promote plant health.
To make seasonal adjustments, consult the user manual. The SST-900i’s seasonal adjustment feature ensures optimal water usage throughout the year, adapting watering schedules to match seasonal conditions.
