DIG LEIT-1 ASV-075 Solar Powered Irrigation Controller With ¾ Anti-siphon Valve DRIP IRRIGATION

DIG’s LEIT 1™ ASV single-station ambient light (solar) powered controller with a two wire DC latching solenoid is available mounted on a ¾” or 1” heavy duty anti-siphon valve for residential and commercial applications. 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. Distinguished among the LEIT-1™’s features are twenty preset monthly historical Evapotranspiration (ET) programs for spray heads and drip irrigation, with an editing feature that can be used as part of the controller programming.
