The LEIT 1 single-station ambient light (solar) powered controller with two wires, DC latching solenoid is available with thee adapters to fits most valves. Powered by a photovoltaic module with a patented microelectronic energy management system, the LEIT 1 requires no batteries, AC power, or direct sunlight to operate, and can be installed above grade in any location where there is ambient light.

The controller employs the latest in water conservation features and can be pre-set to automatically adjust the watering durations according to regional seasonal changes.

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.
