DIG LEIT Solar Powered controller LEIT1 ILV-150 with 1 1/2ʺ inline Valve

Ambient Light Powered Irrigation Controller

Powered solely by ambient light (solar), DIG has developed a fully self-sustainable irrigation controller that doesn’t use batteries or an AC power source. The LEIT-1 requires no direct sunlight and can obtain enough power from surrounding light to operate both day and night in any weather condition. In addition, the LEIT-1 employs SimpleSmart™ programming which automatically adjusts irrigation schedules monthly to help eliminate over and under watering, ensuring a healthy landscape while saving water

Saves Water

• SimpleSmart™ ET feature automatically adjusts irrigation schedules monthly

• Rain- and moisture-sensor compatible

• Daily and monthly programming restriction options to comply with city and municipal watering restrictions

Uses Clean, Sustainable Solar Power

• No batteries to change or replace

• No direct sunlight required

• No wires


• Easily retrofits to most manufacturers’ valves

• Three solenoid valve adapters included

Programming Features

• Five start times per day provide added flexibility for any type of watering application including sandy or clay soil

• Valve duration up to six hours in one-minute increments

• Custom programming schedules using weeks, odd days, even days or intervals of 1-30 days utilizing a yearly calendar with leap year

• Twenty historical ET programming presets with 10 climate zones, 10 for drip irrigation and 10 for spray systems

• Monthly seasonal adjustment that modifies the watering duration from 5% to 200% in 5% increments without modifying the controller’s program duration

• Irrigation suspension (rain delay) for up to 99 days; resumes irrigation automatically

• Rain Delay with up to 99 days with auto restart
