INTRODUCTION
Thank you for purchasing one of DIG’s 7X0A Series, Two, Four or Six Stations Battery
Operated Controllers. This manual describes how to get the controller up and running
quickly. Please read this manual and become familiar with the basic functionality of
the controller, then save and use the manual as a reference for less common tasks
in the future.
1. ABOUT THE CONTROLLER
The 720A, 740A and 760A battery operated controllers employ the latest
irrigation programming features to allow for complete control of any irrigation
system. The controllers operate two, four or six stations and include a master
valve and rain sensor. The controllers are powered by two AA alkaline batteries
that can last up to one year using name brand alkaline batteries, depending
on the number of programs and valves in use. The 720A, 740A and the 760A
controllers are enclosed in a rugged, compact, waterproof housing (IP68) to
protect them from the elements and to ensure a long, trouble-free life.
Features:
• Operates up to six stations, master valve, and a sensor
• Four independent programs with five start times per each valve
• Watering frequencies including weekly, odd, even, and cyclical
• SimpleSmart™historical ET feature for spray heads and drip irrigation
automatically adjusts irrigation schedules monthly
• Can operate any number of valves at the same time
• Upon insertion of the batteries, the controller follows a start-up sequence to
test that each solenoid is closed
• Irrigation suspension (rain mode) with automatic restart of up to 99 days
• Monthly water budget up to 200% in 5% increments
• Daily and monthly programming restriction options to comply with city and
municipal watering restrictions
• After 15 minutes the controller screen turns off automatically to conserve energy
• Manual operation by valve or by program
• Program On/Off button allows the user to turn off the controller and reactivate
it as desired
• Utilizes RoHS compliant components

4. CONTROLLER WIRE CONNECTION
The 720A, 740A and the 760A controllers have a set of red wires numbered for each valve
as well as one black wire for master valve, two white wires for common, and one looped
yellow wire “S” for a rain sensor connection.
4.1 CONNECTING THE WIRES:
1. Connect each numbered red wire to a corresponding red DC solenoid wire (DIG model
#S305DC DC latching solenoid recommended).
2. Connect each white solenoid wire to
one of the two common white wires
from the controller using waterproof
splice connectors (Figure C).
NOTE: If a master valve is installed and
set to active, it will operate and open
with the first valve and will close with
the last valve.
WARNING: Do not strip the master
valve or sensor wires unless using a
master valve or rain sensor.
3. After installation, test each valve via the
solenoid by turning the solenoid one or two turns counterclockwise to open and clockwise
to close. If a valve remains open via a manual operation, you may need to examine the
solenoid and the adapter used to see that they are installed correctly. Make sure the
adapter and the solenoid are firmly secured but not over tightened.
WARNING: If using valves with built-in internal manual bleed levers: make sure
the lever is in the auto (closed) position. Do not move the manual lever after
installing the adapter and solenoid.

5. BATTERY INSTALLATION
1. Turn the battery compartment cap
counterclockwise to open.
2. Install two, fresh, brand name, AA alkaline
batteries (not included) and note the proper
positive and negative orientation on the
underside of the controller body (Figure D) .
3. Insert and screw the battery cap clockwise
to close. Make sure to secure the cap tightly
by hand only. The controller display will appear with day, PM, and the hour digit
flashing. The controller is now ready to be programmed.
NOTE: Upon insertion of the batteries, the 720A, 740A, and 760A controllers will
follow a start-up sequence in which they send an off pulse to each of the attached
solenoids to verify that each of them is closed. This is delineated by all of the
valves appearing on the display, flashing. As a pulse is sent, each valve will stop
flashing, and, if they are not programmed, disappear from the display. After the
start-up sequence has finished, the time will appear on the display and program-
ming can proceed.
6. INSTALLATION RECOMMENDATIONS
6.1 S305 DC SOLENOID ONLY INSTALLATION:
1. Shut off the main water supply.
2. Remove the existing AC solenoids from each valve (if applicable).
NOTE: If adapting to an IRRITROL valve, remove the AC solenoid but leave the
existing solenoid adapter installed.
3. Select the appropriate solenoid adapter associated with the valve used (Figure E).
