The SVC is ideal for applications where electrical power is absent using only a 9-volt battery to operate. The SVC does not require running electrical wires underground since it mounts directly to a valve resisting moisture intrusion, mud and debris as deep as 12 feet. Programming an SVC is easy. Three ingredients are required for each station: a start time, a run time, and days to water. Each station allows you to program up to 9 start times, which means that you can possibly run up to 9 cycles in one day. You can schedule your irrigation on specific days of the week or choose interval watering.
