1. ABOUT THE CONTROLLER
Thank you for purchasing DIG’s ECO 1™ Single Station Battery Operated Controller.
This manual describes how to get the ECO 1 controller up and running quickly.
After reading this manual and becoming familiar with the basic functionality of the
controller, use the manual as a reference for less common tasks in the future.
1. ABOUT THE CONTROLLER
The is a one-station, ambient light (solar) powered smart controller that uses a
patented energy management system to power the controller day and night. The
controller requires no batteries, AC power or direct sunlight and can be installed
above grade anywhere in the landscape.
Employing the latest in water conservation features, the ECO 1 can be pre-set
to automatically adjust the watering durations according to regional seasonal
changes.

4. ANTI-SIPHON VALVE INSTALLATION
The ECO1 ASV.075 can be installed directly to PVC pipe. (Inlet 3/4 in. FNPT, outlet
3/4 in. FNPT.)
Operating pressure: 10 to 125 PSI
Recommended operating pressure: 10 to 80 PSI
NOTE: Wrap all fittings with Teflon tape.
Do not use pipe cement on the valve as this will damage the valve and void
the warranty.
Make sure when wrapping fittings with Teflon tape that no excess gets into the
internal assembly. Tighten the fittings with a wrench, but do not over tighten.
NOTE: The ECO1 ASV.075 must be installed at least 6 in. higher than the highest
sprinkler head on the system or back-drainage may occur. Additional control
valves must not be installed downstream of the anti-siphon valve. The valve must
not be operated continuously for more than 12 hours in any 24-hour period.
Consult local codes for specific details.
1. Flush main line until water runs clear before installation.
2. Shut off main water supply.
3. Install the anti-siphon valve directly to PVC pipe using 3/4 in. PVC male adapter
or use Schedule 80 nipple. The arrow on valve body indicates direction of water
flow (see Figure 6).

4.1 CHANGING ACTUATOR ADAPTERS
The ECO 1™ with actuator is factory set to fit a 3/4 in. brass manual anti-siphon
valve. To install the controller with actuator on a 1 in. manual anti-siphon valve
the 3/4 in. seat washer and adapter must be removed and replaced with the 1 in.
adapter and seat washer, which are included in this box.
1. Turn the actuator so that the seat washer and the 3/4 in. threaded adapter face up.
2. Using pliers, or a 5/18 in. wrench,
remove the seat washer screw by
turning counter clockwise
and pull off the 3/4 in. seat
washer assembly
(see Figure A).
3. Push the 3/4 in. threaded adapter
down towards the actuator to
ease the tension on the retainer
clip (see Figure B).
4. Next, place your thumb on one
side of the retainer clip and with
a pair of pliers grip the other
side of the retainer clip and pull
outwards, away from your thumb,
and upwards, removing it from
the base of the 3/4 in. threaded
adapter then, remove the adapter (see Figure C).
4. Turn the main water supply on and pressurize the system.
5. To test the ECO 1™, press the button. A click will be heard, indicating the
valve is open. An icon of a droplet on the upper left of the screen and the
run time remaining will appear on the display in 5 seconds. Check that the
system is operating correctly and press the button again to turn it off. A
second click will be heard indicating that the valve closed. The droplet icon
and the manual icon will disappear from the display and OFF will appear
momentarily; then the display will revert to the time of day.
6. Program the ECO 1™ controller (see section 5).

4.2 MANUAL VALVE ACTUATOR INSTALLATION
Operating pressure: 10 to 125 PSI
Recommended operating pressure: 10 to 80 PSI
1. Shut off main water supply.
2. Remove the manual stem from the existing valve and temporarily remove the
anti-siphon cap (Figure A).
3. Replace any existing worn washers with the new ones provided (Figure B).
4. Install the actuator into the manual anti-siphon valve body by turning actuator
clockwise. Tighten firmly, but do not over tighten (Figure C).
5. Install the 1 in. threaded adapter by
pushing it onto the actuator stem
and making sure the notch on the
adapter lines up with the notch on
the stem of the actuator
(see Figure D).
6. Spread the retainer clip with your
thumbs and push the retainer into
the adapter until it clicks
(see Figure E).
7. Install the 1 in. seat washer
assembly as shown. Insert the seat
washer screw into the bottom of the
actuator stem and tighten turning
clockwise (see Figure F).
NOTE: Do not over-tighten.

5. PROGRAMMING
In order to program the ECO 1™, you must first let the unit sit out in the light to
charge. In bright light conditions (full sun) this will take under 30 minutes.
In shaded conditions this could take up to 2 hours.
This section explains the programming features, and the steps necessary to assign
irrigation schedules. To program the controller use the to select the desired
programming mode, the to make the entry flash and the buttons to
change the value.
NOTE: Only a flashing value can be changed.
NOTE: If the last data entered stops blinking, press again to resume
programming and repeat the steps.
6. SETTING TIME AND DATE
The controller can display the time in either a 12 or 24 hour format.
To change the time format, from the home screen:
1. Press and hold the button for three seconds until the display switches
format (AM/PM disappears).
SETTING THE CURRENT TIME AND DATE
To enable the controller to operate properly, the current time and date must
be set.
1. Press the button, until the icon appears along with the time and the day
of the week.
5. Turn actuator flow control knob clockwise until it stops to shut off flow
(Figure D).
6. Turn on main water supply.
7. Activate the solenoid through the controller, a click will be heard indicating the
valve is open. (The manual symbol will appear on the display.)
8. Turn the actuator flow control knob counter clockwise to allow flow and check
the system to make sure that the sprinklers or the drip system is working
properly (Figure E).
9. De-activate the solenoid through the controller, a faint click will be heard and
the valve should close. (The manual symbols will disappear and water flow will
stop). If flow continues, turn flow knob clockwise, one full turn at the time until
flow is completely shut off.
10. Repeat steps 7 and 9 and make sure that flow is turned on and off.
Note: Turn flow control knob clockwise to decrease flow, counter-clockwise to
increase flow. For low-flow drip systems below 60 gallons per hour, flow control
knob should be turned no more than 1 to 3 turns up
(counter-clockwise) from the fully closed position.
11. The unit is now ready to be programmed.

9. SETTING WATERING RUN TIMES
Note: If you have already set a SimpleSmart™ ET preset (example: SP02) and then
change the run time, your SimpleSmart™ program will be turned OFF. You must
reactivate the SimpleSmart™ programming each time you adjust your run time
(see section 10).
This setting determines the length of time the ECO 1™ smart controller will allow
the valve to remain open (duration is from 1 minute up to 6 hours). For example,
setting watering run time to 10 minutes on certain days of the week will program
the controller to turn the water on for 10 minutes on each of the days chosen and
at every start time selected.
To set the watering run time :
1. Press the button until the icon appears and OFF or the last run time
setting appears.
2. Press the button, and OFF (or the last run time programmed) appears with
hours blinking.
3. To set a desired watering run time in hours, press or and select the
number of hours.

programmed) appear blinking.
7. To set the desired second start time hour (note AM and PM designations), press
or .
8. Press again and the minutes begin blinking, press or to select the
watering start time in minutes. Repeat the steps to set the third and if needed
the fourth and fifth start times. During programming, the screen also shows
which days the controller will operate.
Press the button to proceed to the next step RUN TIME or to review
the program.
