Orbit 57900 Irrigation Controller Details
The Orbit Model 57900 Irrigation Controller, a key product in its series, is designed for convenience and flexibility in managing watering schedules. It features Orbit's exclusive Easy-Set Logic™, simplifying programming and setup by integrating advanced timer technology with versatile functionality. Users can easily implement fully automatic, semi-automatic, or manual watering programs tailored to their specific landscape requirements. This ensures that even complex irrigation needs are met with straightforward controls and an intuitive interface, making efficient water management accessible. A durable, weather-resistant cover with a lock and latch protects internal components from the elements.
The controller boasts an intuitive interface, comprising a prominent dial for mode selection, a clear digital display, and dedicated buttons for precise adjustments (ENTER/MANUAL, CLEAR, PROGRAM, arrows, +/-). The dial guides users through settings like SET CLOCK, SET DATE, START TIME, RUN TIME, HOW OFTEN, BUDGET, and OFF. A standout capability is its support for three independent programs (A, B, C), allowing distinct watering schedules for different zones or plant types. Each program can have up to four daily start times, and start-time stacking intelligently delays subsequent programs to prevent overlap, optimizing water distribution.
To accommodate diverse watering needs, the Orbit 57900 offers flexible frequency settings: users can select specific Days of the Week, define watering Intervals (e.g., every 'X' days), or choose Odd or Even Day watering. Furthermore, it integrates smart features for environmental adaptation. The Rain Delay function pauses watering for 24, 48, or 72 hours, conserving water after rainfall, with the display showing the remaining delay. Water Budgeting allows percentage-based adjustments (10% to 200%) to overall watering durations, effortlessly matching seasonal requirements like hotter summers or cooler springs.
For immediate or specific watering tasks, the Orbit 57900 provides robust Manual Watering options. Users can initiate watering for all stations consecutively or precisely select individual programs or stations, adjusting durations from 1 to 240 minutes without altering the programmed schedule. This is invaluable for spot watering or system testing. For comprehensive irrigation system management, the timer supports the integration of a pump start relay or master valve, activating them automatically with any running station. Dedicated terminals and a bypass switch are also included for easy rain sensor connection, further enhancing water conservation.
Installing the Orbit 57900 is designed to be straightforward. Key considerations include selecting a location near a power source, ensuring operating temperatures are within 32°F-158°F (0°C-70°C), and providing 9 inches of clearance for the swing door. Wiring involves connecting individual valve wires to corresponding station terminals and a common wire to the common terminal, with recommendations for wire gauge based on distance. The timer requires one CR2032 lithium battery, which should be replaced annually to retain programming memory during power outages. A built-in fail-safe program waters each station for 10 minutes daily if memory is lost.
