SL800 Technical Information The Most Feature Rich, Economical Controller - EVER! FEATURES 4-zone base model, expandable to 8 zones using slide-in SLM2 2-zone hot-swappable modules (Indoor rated)  External transformer with plug-n-play barrel connector Skip circuit and slow blow fuse protection with green/red LED status indicator Large 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 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) 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 - 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.;
