6.1 PROGRAMMING METHOD

Mode Button – used to select the appropriate programming screen

(e.g.) clock setting mode.

Data decrement (decrease) – lowers the value of the selected parameter

(e.g. deducts an hour).

Data increment (increase) – raises the value of the selected parameter

(e.g. adds on an hour).

Flash button – used to select the parameter to be changed

(e.g. hour, minute, etc.) To implement the change, the selected parameter

must be flashing.

If no changes are implemented, the timer display will always revert to the main

screen (clock).

NOTE: If the timer is not programmed the clock will flash continuously. After 10

minutes the timer will implement 5-minute irrigation duration on a 24-hour cycle

(default mode).

7. ADDITIONAL DISPLAYS

7.1 BLINKING LOW BATTERY WARNING

A flashing battery icon appears on the display when the batteries are weak. At this

point, the battery still contains a limited amount of energy for valve operation. The

battery should be replaced promptly.

If the battery is not replaced, the irrigation timer

will continue to open the valve 8 additional

times according to the program. It will then

suspend the program and “OFF” will appear on

the screen.

Program data will be retained for 30 seconds

during battery changing.

An irrigation timer without a battery will not

operate the valve.

7.2 MISSING DEFINITION IN IRRIGATION PROGRAM

will appear if irrigation days have not

been specified after programming (see Section 9).

In this case, the valve cannot be opened for

manual operation.

7.3 PROGRAMMING ERROR

In the cyclical program (see section 9) if the

irrigation duration programmed is equal to or

longer than the irrigation cycle, the word

will appear.

To cancel the error, press

or to increase

the irrigation cycle.

8. HELPFUL HINTS AND ADDITIONAL INFORMATION

1. A manual run can be started at any time when current time is displayed by

pressing the manual button once. The valve will operate one time for the length

of time programmed and then proceed back to the normal programming.

2. All DIG timers can be programmed in the comfort of your home or office and

installed at a later date. No water pressure is required.

3. Always make sure that the battery compartment is clean and dry. If water

should get on the battery, immediately remove and wipe clean.

4. We strongly recommend brand name alkaline batteries. Rechargeable batteries

are not recommended.

5 Under normal usage, batteries (alkaline) will last for a minimum of 1 year,

maximum of 2 years.

6. It is good operating practice to replace old batteries with new ones at the start

of the irrigation season.

9. MAINTENANCE AND SPECIFICATIONS

• Recommended operating water pressure range: 10-80 PSI

• Operating water pressure range: 10-125 PSI

• Flow rates: .5-28 GPM

If the timer is not going to be in use for an extended period of time, remove

batteries and replace cover securely. After an extended period without batteries the

timer will need to be reprogrammed. During battery replacement programming will

be retained for up to 30 seconds.

KEEP BATTERY COMPARTMENT SECURELY CLOSED AT ALL TIMES.

Remove timer and store indoors when temperature drops below 32° for a

prolonged period of time.

Be sure to shut off water supply before removal.

10. TROUBLESHOOTING AND REPAIRS

PROBLEM: Valve does not open during automatic operation or during “manual”

operation via irrigation timer.

CAUSE: Solenoid is too tight.

SOLUTION: Turn solenoid counter clockwise.

CAUSE: Main line is closed.

SOLUTION: Open manual main-line service valve.

PROBLEM: No display.

CAUSE: Weak batteries.

SOLUTION: Replace batteries.

PROBLEM: Valve does not close despite clicks heard during activation.

CAUSE: Outlet flow may be too low (minimum flow 30 GPH or .5 GPM).

SOLUTION: Increase flow rate by adding drip emitters, micro sprinklers

or sprinklers.

CAUSE: Valve is installed backwards.

SOLUTION: Reverse valve.

CAUSE: Solenoid port(s) are blocked.

SOLUTION: Shut off water supply. Unscrew solenoid and remove from

valve (take care to not lose plunger). Open water supply and flush out

valve solenoid ports. Re-install solenoid by turning clock-wise into

bonnet, (make sure plunger is in place). Open water supply and push

manual button twice to verify valve opens and closes.

PROBLEM: Water discharges from parts below bonnet.

CAUSE: Valve is installed too low.

SOLUTION: Raise valve so it is a minimum of 6” above highest

sprinkler head.
