Avoid rushing to ensure a secure and aligned mount, crucial for reliable operation.

3.2 Connecting Power and Water Sources

Connect the Rain Bird SST-400i timer to a GFCI-protected outlet for power. Attach the main water supply line to the timer’s inlet, ensuring a secure connection. Connect the zone wires to the corresponding terminals, matching each zone to its valve. Turn on the main water supply and check for leaks. Ensure all connections are tight and properly sealed before testing the system. This step ensures reliable operation and prevents water damage or electrical issues.

Programming the SST-400i Timer

Program the SST-400i timer with ease, setting the clock, date, and customizable watering schedules to ensure efficient irrigation tailored to your lawn’s needs.

4.1 Setting the Clock and Date

Setting the correct time and date is essential for proper timer operation. Use the dial to select “SET CLOCK” and adjust the time using the ‘+’ and ‘-‘ buttons. Next, set the date by scrolling through the options. Ensure the time is in 12-hour format (AM/PM). Once done, save your settings to synchronize the timer with your watering schedule. Accurate time and date settings are crucial for reliable irrigation operations. This ensures your programmed schedules run correctly and efficiently.

4.2 Creating Watering Schedules

To create a watering schedule, select a zone and set the start time, duration, and frequency. Choose from options like daily, every other day, or specific days of the week. Adjust the runtime for each zone based on plant and soil type. Use the dial to navigate and the ‘+’ or ‘-‘ buttons to modify settings. Save your schedule to ensure automatic irrigation. This feature allows you to customize watering cycles for up to 6 zones, optimizing water usage and plant health.

4.3 Using the Rain Delay Feature

The Rain Delay feature allows you to pause watering schedules for 24, 48, or 72 hours. Press the ‘RAIN DELAY’ button and select the desired delay duration using the ‘+’ or ‘-‘ buttons. This feature is ideal for conserving water during rainy or cool weather. Once activated, the timer will skip all scheduled watering cycles during the selected period. After the delay ends, the system automatically resumes its normal watering schedule, ensuring efficient water usage and plant care.

Advanced Features and Accessories

Explore advanced features like rain sensors and master valves for enhanced water management. Accessories integrate seamlessly, offering improved control and efficiency for your irrigation system.

5.1 Connecting a Rain Sensor

Enhance your irrigation system by connecting a rain sensor to your Rain Bird SST-400i timer. This accessory helps prevent overwatering by detecting rain and delaying scheduled waterings. To install, locate the sensor port on the timer, remove the wiring bay cover, and plug in the sensor. The sensor provides real-time weather data, optimizing water usage. Ensure compatibility with your SST-400i model for seamless operation. This feature is also compatible with other SST models like SST-600i and SST-900i.

5.2 Using a Master Valve or Pump Start Relay

A master valve or pump start relay enhances your irrigation system by controlling the main water supply. The master valve connects directly to the timer, while the pump start relay operates similarly but connects differently at the water source. Both options improve system efficiency and reduce wear on your irrigation components. Ensure compatibility with your Rain Bird SST-400i model for optimal performance and seamless integration.

Troubleshooting Common Issues

Identify common issues like power outages or faulty connections. Check wiring, reset the timer, and ensure proper water supply. Consult the manual or contact support for unresolved problems.
