Time Switches
Sprinkler/Irrigation Timer with 14-Day Skipper
These irrigation timers permit 1 to 60 “ON” operations every 24 hours. This series is designed for water
metering in increments of 12 minutes to 20 hours and 45 minutes for maximum conservation of precious water
resources. The 14-day skipper feature permits irrigation to be omitted on selected day(s) and also provides
for “every other” day operation. The “ON/OFF/AUTOMATIC” switch allows shutdown during rainy days or
extended watering during dry periods without disturbing the automatic cycle set on dial.
