Actuator with
Watering Timer

1. INTRODUCTION
Thank you for purchasing DIG’s RBC MVA 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 MVA BATTERY OPERATED TIMER
The RBC MVA Timer employs the latest irrigation programming features to allow for
complete control of any irrigation system. The RBC MVA is a single station battery
operated timer with a factory pre-assembled actuator to convert a 3/4 in. Champion
or Orbit manual brass anti-siphon valve. It is also includes a 1 in. adapter and seat
washer to fit 1 in. Champion or Orbit manual brass valves, 3⁄4 in. and 1 in. Rain Bird
manual plastic valves, or 3⁄4 in. and 1 in. Orbit plastic valves. The timer has 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.

6.1 CHANGING ACTUATOR ADAPTERS
The RBC MVA timer 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 1in. 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 5/16 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).

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.

6.2 MANUAL VALVE ACTUATOR INSTALLATION
Rated operating pressure: 20 to 125 PSI
Recommended operating pressure: 20 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). Re-install anti-siphon
cap.
v
5. Turn actuator flow control knob clockwise until it stops (Figure D).
6. Turn on main water supply.
7. Activate the solenoid through the timer manual button, 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 timer’s manual button, a faint click will be heard
and the valve will close. (The manual symbol will disappear and water flow will stop).
If flow continues, turn flow knob clockwise, one full turn at the time until flow is
stopped, and the valve is shut off.
10. Repeat steps 7 and 9 and make sure that flow is turned on and off.
Note: Turn the 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.

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.
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
turning the external bleed screw 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 6000 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.

16. MAINTENANCE, TROUBLESHOOTING AND REPAIRS
To restore the timer to the default settings
1. Press the button until the START EVERY is displayed and the icon
appears on the bottom left of the screen.
2. Press and hold down the for three seconds.
3. The screen returns to the home screen (clock) and all the default settings are

PROBLEM: Timer fails to open automatically or manually
CAUSE: No water pressure
SOLUTION: Open main water supply valve
CAUSE: Flow control knob is turned down
SOLUTION: Turn flow control knob clockwise to open
PROBLEM: Valve/actuator functions via the manual mode only but
not automatically
CAUSE: Timer is set to OFF mode
SOLUTION: Verify that the timer does not show OFF in current time mode
CAUSE: AM/PM not set correctly in current time mode
SOLUTION: Check current time, change AM/PM if necessary
CAUSE: AM/PM not set correctly in start time mode
SOLUTION: Check start time(s), change AM/PM if necessary
CAUSE: Rain delay is preventing watering
SOLUTION: Set rain delay to off
CAUSE: Yellow sensor wires have been cut
SOLUTION: Re-connect sensor wires together with waterproof connector
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 MVA 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 MVA timer be checked regularly and the batteries
replaced once the low battery indication starts flashing.
The RBC MVA 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.:

SOLUTION: Increase system flow rate by adding or changing drippers
PROBLEM: Rain sensor does not prevent watering
CAUSE: Rain sensor is normally open, malfunctioning, or not wired correctly
SOLUTION: Verify that sensor icon appears on display when pin is pushed
down & check all wire splices
PROBLEM: Timer waters more than once per day
CAUSE: More than one start time has been programmed
SOLUTION: Change start time 2,3, and 4 to OFF
