DIG LEIT-1 ILV-150 Irrigation Controller

Yes. It uses a photovoltaic module to harvest ambient light, which powers the unit. As long as the installation site receives enough light—between 3,000 and 100,000 LUX—it will operate continuously without needing battery replacements or electrical wiring.

Because it relies on ambient light, it is not suitable for dark, enclosed spaces like deep valve boxes. It must be installed in a location that receives consistent, sufficient light to maintain its power supply.

The controller features non-volatile memory, meaning your programmed settings are saved permanently. If light levels drop below the operating threshold, the unit will pause, but it will resume your exact schedule as soon as sufficient light returns.

The LEIT-1 is designed to work with 7-12 VDC two-way latching solenoids. It supports a wide range of globe valve sizes from 3/4 inch up to 2 inches, making it compatible with most standard residential irrigation systems.

The controller uses historical evapotranspiration (ET) data to automatically adjust your watering duration based on the season. This helps ensure your landscape receives the appropriate amount of water without you needing to manually reprogram the timer every few weeks.

Yes, it carries an IP68 rating, which means it is fully protected against dust and can withstand prolonged immersion in water. This makes it highly durable for outdoor environments where it might be exposed to heavy rain or wet conditions.
