DIG ECO1™ASV solar powered irrigation controller mounted on a 3/4” anti-siphon valve can be used with drip irrigation or sprinkler systems. The anti-siphon valve features flow control with internal and external bleed and is used to protect the household water supply from contamination. The controller’s power is derived via a patented, time-tested internal photovoltaic module and microelectronic energy management system that is fueled by ambient light (solar). This provides power to the controller through the day anytime, anywhere and in any weather.
The controller uses features that include five start times per day, watering duration of up to 5 hours and 59 minutes, Manual Run, Monthly Budget, Rain Off with restart in up to 99 days, System Off and Irrigation Off for any month of the year. It also has additional features that include daily watering restrictions that can be used on any watering event that requires curbing by cites and municipalities. The ECO1™’s main features include 20 preset programs of historical Evapotranspiration (ET) for spray heads and drip irrigation with an editing feature that can be used as part of the controller programming. Combining one of the historical Evapotranspiration preset programs and a rain sensor can help seasonally adjust or prevent unnecessary watering and save water. After installation, no further visits to the controller are required.
|Single Station Ambient Powered Controller with 3/4 in. Anti-Siphon Valve
The ECO1™ ASV solar-powered irrigation controller with a 3/4″ inlet and female pipe thread outlet should be installed a minimum of 6″ above the highest sprinkler onto a 3/4″ PVC male pipe thread fitting or riser as part of your drip irrigation or sprinkler system valve manifold, or as a stand-alone unit. Make sure that the valve is installed with the flow direction arrow engraved on the side pointed away from the water source, and that the solenoid is on the outlet side of (downstream from) the valve.
The anti-siphon valve is frequently required on outdoor irrigation systems. It is a directional valve that allows water to flow in only one direction and prevents irrigation water from returning back or back siphoning to the drinking water supply line, preventing contamination of the water supply. It is open to the atmosphere when there is reduced or no pressure in the line. Install the controller with anti-siphon valve at least six inches above the highest sprinkler or elevated line within the station.
Recommendations: Wrap all fittings with TEFLON tape. Do not use pipe cement (solvent) or pipe dope on the valve as it will damage the valve thread and void the warranty. Do not over tighten.
Programming: This controller uses seven programming buttons to navigate through its high resolution LCD icon based display. The controller’s four buttons (left, right, up and down arrows) are used to select or modify a program parameter, the large button in the center is used to accept the parameter change and move or skip to the next step or icon, the right lower button is used for manual on/off, and the left lower button is used for program off or to stop irrigation when it is raining.
This controller requires light as the source of energy and will take about 45 minutes to charge.

If a rain sensor or other closed contact sensor is used, cut the yellow wires and add the sensor per the sensor instructions, making sure to use a waterproof wire connection.
