LEIT 1 with 3/4″ or 1″ Anti-Siphon Valve
DIG’s LEIT 1™ ASV single-station solar powered controller with a two-wire DC latching solenoid is available on a 3/4″ or 1” heavy duty anti-siphon valve for use in residential and commercial applications. Powered by a photovoltaic module with a patented microelectronic energy management system, the LEIT 1™ requires no batteries or direct sunlight to operate, and it is used above grade in any location where there is light. Distinguished among the LEIT-1™ features are 20 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.
