The Sterling 24 Station Controller features six independent programs that can run concurrently. There are up to 9 daily cycle starts per program. A loop watering option is also available in all six programs for unlimited cycles. There is no limit on the number of programs to which a station can be assigned. Station timing is adjustable from 1 minute to 24 hours in 1 minute increments. Seconds and minutes time base is optional in all six programs. An illuminated LED lets you know if a program is in the seconds and minute mode. A programmable pause of 1 second to 59 seconds between stations allows full valve closure before advancing to the next station.
