DIG’s LEIT 1 is a single-station solar powered controller mounted on an anti-siphon valve, inline valve or actuator to convert a brass or plastic manual anti-siphon valve. 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, it employs Simple Smart™ programming which automatically adjusts monthly irrigation schedules to help eliminate over and under watering, ensuring a healthy landscape while saving water.
