Weathermatic SMARTLINE 4 Station Indoor Controller | SL800

WEATHERMATIC SL800 4 ZONE BASE CONTROLLER:

4-Zone base model controller / timer with external transformer.

• 4-zone base model, expandable to 8 zones using SLM2 2-zone hot-swappable modules (Indoor rated)
• External transformer with plug and play barrel connector
• Large LCD display
• 2 run modes: Standard mode runs user input zone run times; Auto Adjustmode requires SLW Series On-Site Weather Station to calculate weather based run times
• Rain/Freeze sensor bypass/active button displays sensor status with tricolor LEDs (red indicates sensor is prohibiting irrigation; orange indicates an extended rain delay; green indicates normal operation)
• 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
• Seasonal % adjust by program, by month for simple year round water budgeting (monthly percentages overidden in Auto Adjust mode)

• Input: 120VAC/60Hz @ 250mA for 3 valves
• Output: 28VAC, 720mA maximum
• Fuse: 1.0A, slow blow
• Dimensions: 7" W x 7-3/4" H x 1-3/4" D (17,8 cm x 19,7 cm x 4,4 cm)

• ZIP Code input (5 digit) or Latitude input (+/-60 degrees 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 - 25 degrees) 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

• Diagnostic test function using on-board multi-meter displays transformer voltage; milliamp measurement for each zone
• Fault review displays all faults, including open and shorted zones
• Built-in valve locator function for locating hidden valves by simply listening for the audible chatter of the solenoid created by a unique electrical frequency (U.S. Patent No. 7,406,363)
• Review menu displays accumulated ET deficits by zone (in inches) and corresponding zone run times for the next available watering day
• Review menu displays maximum run time and minimum soak time used during Auto Adjust mode
• Review menu displays temperature readings (daily high/low) for previous 5 days
• Review menu accumulates total run times by zone from the last reset date
• Rain delay of 1 - 7 days may be selected (to pause and automatically resume operation)
• 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
• Zone-to-zone delay programmable for 1 min. - 3 hrs. to accommodate slow closing valves and recharging of water supply
• Master valve timing sequence with zone-valve programmable by "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
• Master valve/pump start operation assignable On/Off by zone
• 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 SL800
