DIG EVO100 is a hose end tap timer with a 3/4 in female thread inlet and male thread outlet. Power is derived via a patented, time tested internal photovoltaic module and microelectronic energy management system that is fueled by the surrounding ambient light. After being charged, this efficient energy system provides enough power for the timer to function at any time, night or day and in any weather with no direct sunlight required. This energy system also makes the timer environmentally friendly, functioning only on clean renewable solar power without the need for a backup battery or AC power. The EVO100 features a large, easy-to-read LCD screen and simple icon-based programming with weekly or cyclical programs, four start times per day, durations of up to six hours, program delay of up to 99 days, system off, manual operation and a sensor wire connection to accept a rain sensor.
