1. INTRODUCTION
Thank you for purchasing DIG’s RBC 8000 Single Station Battery Operated Timer.
This manual describes how to get the RBC series timer up and running quickly.
After reading this manual and becoming familiar with the basic functionality of the
timer, use the manual as a reference for less common tasks in the future.
2. ABOUT THE RBC 8000 BATTERY OPERATED TIMER
The RBC 8000 watering timer employs the latest irrigation programming features
to allow for complete control of any irrigation system. The RBC 8000 is available
in a single station model which includes a 3/4 in. anti-siphon valve, with a rain
sensor connection, and is powered by two AA batteries that can last up to 3
years [using name brand alkaline batteries]. The timer is enclosed in a compact,
waterproof housing to protect it from the elements.

5. INSTALLING THE BATTERIES
1. Open the battery compartment cap by
turning it counter-clockwise.
2. Install two, fresh, brand name, AA
alkaline batteries (not included)
and note the proper direction of the
positive and negative orientation on the
underside of the timer.
3. Insert and screw the battery cap
clockwise. Make sure to securely
tighten the cover firmly by hand only.
The timer display appears with a day,
PM, and the hour digit flashing. The timer
is ready to be installed and programmed.

6. ANTI-SIPHON VALVE INSTALLATION
The RBC 8000 can be installed directly to PVC pipe with two PVC
male adapters (not included). Inlet 3⁄4 in. FNPT, outlet 3⁄4 in. FNPT.
Rated operating pressure: 10 to 125 PSI
Recommended operating pressure: 10 to 80 PSI
NOTE: The RBC 8000 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 adapters (FigureA1 and A2) or use 3/4 in. schedule 80
nipple. The arrow on valve body indicates direction of water flow.
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.
4. Turn the main water supply on and pressurize the system.
5. To test the RBC 8000, press the button. A click will be heard, indicating the valve is
open. A droplet icon 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. The unit is now ready to be programmed.

12. SETTING RAIN DELAY – OPTIONAL FEATURE
The Rain Delay setting is used to temporarily suspend all irrigation for a defined
number of days. For example, during rainy weather regularly scheduled programs
can be turned off from 1-99 days. At the end of the designated period, regularly
scheduled programming will resume automatically.

or until OFF appears.)
Note: OFF appears in between numeric value of 99 and 1.
Press the button to review the program or to exit.
13. MANUAL WATERING
The manual mode allows the user to test the system and water for a specified run
time set in watering duration. The timer will automatically stop watering at the end of
the defined irrigation period. The originally programmed irrigation schedule continues
to function at the times assigned. The sensor condition is disregarded in this mode.
To start a manual run,
1. Press the button, and the icon and icon appears. ON appears
momentarily and then the last watering duration is displayed with .
The timer will open the valve and in 5 seconds a count down of the remaining
irrigation duration appears, showing when the timer will close the valve.

3. After 5 seconds the display will revert to the current time screen.

16
To activate a manual watering without the use of the timer – turn the solenoid a
1/4 turn counterclockwise. To stop, tighten the solenoid clockwise by hand only –
do not over tighten (figure 8a). Manual watering can also be achieved by turing the
external bleed screen counterclockwise to start and clockwise to stop (figure 8b).

14. CONNECTING A RAIN SENSOR
Most “normally closed” rain sensors can be connected to the RBC 8000 timer.
The function of the sensor is to prevent automatic watering by
the set program due to excessive rainfall.
To connect the sensor to the timer, please follow these steps:
1. Cut the yellow wire loop that exits the timer in the middle of the loop.
2. Strip approximately 1/2 in. of insulation from the end of each wire.
3. Splice one yellow wire to each of the wires coming from the sensor.
Use waterproof wire connectors to secure the connections.
4. When the sensor is active and preventing automatic operation, the icon will
appear on the display.
The icon will only appear when sensor is active or if the wire has been cut.
Recommended rain sensors are the Rain Bird RSD and Hunter Mini-Clik

15. CHANGING THE BATTERIES
The RBC 8000 timer’s batteries can last up to 3 years when using name-brand
AA alkaline batteries. Actual battery life will depend on the sensitivity of the
installed batteries to temperature ranges experienced by the timer as well as the
number of valve operations programmed per day. To ensure proper operation, it
is recommended that the RBC 8000 timer be checked regularly and the batteries
replaced once the low battery indication starts flashing.
The RBC 8000 timer is designed to maintain the current time settings for up to 60
seconds with the batteries removed.
To change the batteries, see section 5.
Note: If the batteries are dead or drained, manual operation can also be
accomplished by turning the solenoid counterclockwise, or by turning the
external bleed screw counterclockwise. This will cause the valve to open.
Both must be turned clockwise to close the valve.:
