Weathermatic SMARTLINE 16 Station Indoor/Outdoor Controller | SL1616

• 4-zone base model controller expandable to 16 zones.

Features & Benefits

• 4-zone base model, expandable to 16 zones using SLM4 4-zone hot-swappable modules (Indoor/Outdoor rated)
• Internal 120VAC/230VAC transformer with plug and play pre-installed 6' line cord (removable for conduit-wired installations)
• Large backlit LCD display
• 2 run modes: Standard mode runs user input zone run times; Auto Adjust mode requires SLW Series On-Site Weather Station to calculate weather based run times that override user input zone run times
• Rain/Freeze sensor bypass/active button located on face panel displays sensor status with tri-color LEDs (red indicates sensor is prohibiting irrigation; orange indicates an extended rain delay after weather station rain sensor permits irrigation; green indicates normal opera
• 4 programs: A, B, C; program D can operate concurrently
• 8 start times per program
• Nonvolatile memory and real time clock/calendar circuit to retain programs as well as correct date and time - with no battery required
• Zone run times settable from 1 min. to 9 hrs. 55 min. with operation countdown displayed in hours, minutes, and seconds (zone run times overridden by weather based calculated values in Auto Adjust mode)
• Watering day selections of custom days of the week, odd/even, or interval days
  Omit settings: omit time of day window, omit day(s) of the week, and omit up to 7 calendar dates
• Seasonal % adjust by program, by month for simple year-round water budgeting (monthly percentages overridden in Auto Adjust mode)

Product Details

• Input: 120VAC/60Hz @ 400mA for 3 valves
• Output: 28VAC, 1.0A maximum
• Fuse: 1.0A, slow blow

Auto Adjust Features

• ZIP Code input (5 digits) or Latitude input (+/-60 degrees from EQUATOR) establish the location of the 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

Advanced Functions

• Fault review displays all faults, including open and shorted zones
• Diagnostic test function using on-board multi-meter displays transformer voltage; milliamp measurement for each zone
• 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 (patent pending)
• Review menu displays accumulated ET deficits by zone (in inches) and the 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 the 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 the 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 the contractor to easily store a default program and retrieve the saved program in the event a customer improperly reprograms the SL800
