SL1600 Applications
Weathermatic has a winner in this controller. It has all of the features you expect in a nice residential/light commercial controller, plus a slew of advanced features.
The modular design provides expandability for every yard and evolving landscapes with the SL1600 4-zone base model. It is expandable to 16 zones using slide-in SLM4 modules. Push-in wiring makes installation quick and easy! SmartLine controllers are really two controllers in one; operate in Standard mode or switch to Auto Adjust mode by simply adding any SLW Series On-Site Weather Station for weather based watering schedules and rain/freeze sensing.
The built-in valve locator locates hidden valves by producing an audible chatter in the solenoid created by a unique electrical frequency (US Patent No. 7,406,363). The on-board multimeter displays the electrical current reading of each zone for quick troubleshooting and a proactive approach to maintenance. Control hydraulic pressure throughout the system using settings for station-to-station delays, master valve timing, and master valve On/Off by zone. Eliminate run off by setting the maximum allowable run time and minimum soak time by program. A monthly watering budget percentage can be set up by program to automatically adjust zone run times for seasonal changes. A feature to backtrack the program to a set of default values enables easy restoring of a standard program.
The ability to omit times, days, and dates allows you to automatically comply with local water restrictions; eliminate irrigated water lost to evaporation in the heat of the day; stop irrigation on lawn maintenance days; never water on the date of an annual event (e.g. July 4th). Includes a backlit LCD, real time clock, calendar and non-volatile program memory. (No flashlight required in dark basements and garages.) No battery required! On board memory chip retains time, date and program information even during a power outage. |
Features:
4-zone base model, expandable to 16 zones using slide-in 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
Two 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 percentage adjust by program, by month for simple year round water budgeting (monthly percentages overridden in Auto Adjust mode)
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
Review menu provides the ability to clear deficits for all zones
Rain delay of 1 - 7 days may be selected (to pause and automatically resume operation)
SLW weather station extended rain delay programmable from 0 to 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 you to easily store a default program and retrieve the saved program in the event you want to temporarily modify the program but return to the standard program later on.
Auto Adjust Features:
ZIP Code input (5 digit) or Latitude input (+/-60° 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°) 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
The Weathermatic SL1600 Controller is compatible with the
Weathermatic SLW10 On-Site Weather Monitor.
Manual Operation:
- Manual test runs each zone with zone run times from 10 sec. - 10 min.
- Manual zone operation of a single zone (1 min. to 9 hrs. 55 min.)
- Push button manual start of a program from control panel
