ECO1™ ASV Single Station Ambient Light Powered Controller with 3/4" Anti-Siphon Valve

The ECO1™ASV ambient light (solar) powered, smart irrigation controller mounted on a ¾” anti-siphon valve and can be used with drip irrigation or sprinkler systems. The anti-siphon valve features flow control with internal and external bleed and is utilized 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 ECO1™ASV ambient light (solar) powered, smart irrigation controller on anti-siphon valve uses features that include five start times per day, durations 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. The controller also has additional features that include daily watering restriction that can be used on any watering event that requires curbing by cites and municipalities.

how to use


ECO1™ ASV Single Station Ambient Light Powered Controller with 3/4" Anti-Siphon Valve

###About
The ECO1™ ASV Single Station ambient light (solar) powered, smart irrigation controller with 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.

Power

This controller requires light as the source of energy and will take about 45 minutes to charge.
Review the instruction manual included with the unit for details.

Installation into a PVC pipe or to pipe thread

  1. If installation is into a PVC pipe, first shut off the main water supply.
  2. We recommend installing a 3/4" ball valve or gate valve before the battery operated controller. This ball valve can be very useful as an emergency backup to turn the system off. This type of arrangement is used by professional installers.
  3. Turn the water supply on to flush the line and then shut the water supply off using the new ball or gate valve.
  4. Install the controller with the anti-siphon valve a minimum of 6" above ground, wrapping TEFLON tape on all the male thread fittings used.
  5. Turn the water supply on again to pressurize the system. The controller will open momentarily and then will shut off.
  6. Test the controller using the manual on/off button located on the upper right side. Press the button and the controller will turn on. Check that the system is working and that there are no leaks. Press the button again and the controller will turn off.
  7. Program the controller.
  8. If the controller is installed with a drip irrigation system, make sure to add a 15, 25 or 30 PSI pressure regulator to lower the pressure to the drip system, then install a 150 or higher mesh screen filter to protect the drip system, following with a swivel adapter to the drip tubing.

Review the instruction manual included with the unit for details

Adding a rain sensor or any other closed contact sensor

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.
