  • 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 overridden in Auto Adjust mode)

Specifications
