The LEIT 1™ single-station ambient light (solar) powered controller with actuator is use to retrofit ¾ inch or 1 inch manual anti siphon valve. 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.
