• 4 programs: A, B, C; program D can operate concurrently
• 8 start times per program
• Nonvolatile memory and real time clock/calendar to retain programs and current date and time - no battery required
• Zone run times from 1 min. to 9 hrs. 55 min. with operation countdown displayed in hours, minutes, and seconds
• Watering day selections of custom days of the week, odd/even, or interval days (1 - 30 days)
• Omit settings: omit time of day window, omit day(s) of week, and omit up to 7 calendar dates
• Monthly % adjust by program, for simple year round water budgeting

• Fault review displays all faults, including open and shorted zones
• On-board multi-meter displays transformer voltage; milliamp measurement for each zone
• Built-in valve locator chatters the solenoids (U.S. Patent No. 7,406,363)
• Review menu displays ET deficits by zone , and corresponding zone run times
• Review menu displays maximum run time and minimum soak times
• Review menu displays temperature readings (daily high/low) for previous 5 days
• Review menu accumulates total run times by zone
• Programmable rain delay of 1 - 7 days
• SLW Weather Station extended rain delay programmable from 0 - 99 hours
• Run/Soak cycles allow setting of maximum run time and minimum soak time by program for use in Standard mode only
• Programmable zone-to-zone delay 1 min. - 3 hrs.
• Programmable master valve timing sequence with ??On Delay" (1 sec. - 1 min.; 2 sec. default) and ??Off Delay" (1 sec. - 3 min.; 5 sec. default) to allow for line fill and slow-closing valves

• Clear program function to selectively delete an individual program
• Clear all function to delete all programs
• Backtrack stored program feature allows contractor to easily store a default program and retrieve the saved program in the event a customer improperly reprograms the SL4800

• ZIP Code input (5 digit) or Latitude input (ñ60ø from EQUATOR) establish location of site for solar radiation calculation
• Sprinkler type input allows selection for zone sprinkler type (SPRAY, ROTOR, DRIP, BUBBLER) with preset precipitation rate or specific input of the zone precipitation rate (.2 - 3.0" per hour)
• Plant type input allows selection for zone plant type (COOL TURF, WARM TURF, SHRUBS, ANNUALS, TREES, NATIVE) with preset crop factors or specific input of the zone crop factor (10 - 300%)
• Soil type input allows selection for the soil type (CLAY, SAND, LOAM) and slope (0 - 25ø) for the purpose of automatically calculating a run/soak period to virtually eliminate run off
• More/Less is settable by zone (-50% to +25%) for the purpose of fine tuning Auto Adjust run times to accommodate factors like shade, wind, and sprinkler inefficiencies

• Manual test runs each zone with zone run times from 10 sec. up to 10 min.
