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 operation)
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
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)
Specifications
Input: 120VAC/60Hz @ 400mA for 3 valves
Output: 28VAC, 1.0A maximum
Fuse: 1.0A, slow blow
Dimensions: 9-1/8" W x 10-1/2" H x 4" D (23,2 cm x 25,7 cm x 10,2 cm)
Auto Adjust Features
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
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 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
