Thank you for choosing the RainJet@ RJ6 Automatic Sprinkler Timer.The R J6 is
simple to operate and provides flexible programming capabilities to help meet
your specific watering needs.
With the RJ6, you can set an automatic watering schedule and still activate
a manual watering cycle without having to reprogram. You can also temporarily
suspend your program, on rainy days for instance, again without affecting your
original program.
Some of the other convenient features of the RJ6 include:
*One program, adaptable to individual watering requirements
*Three start times
-Six zone capacity
*Watering on specific days of the week or odd/even days
*Watering durations from I minute to 99 minutes
-Easy-to-use push-button programming with large, easy-to-read
LCD display
-Quick reference programming guide on the inside of the terminal
cover
*Programming capability before timer is mounted permanently,
using just a 9 volt battery
If you have any questions about the installation or operation of your
RJ6,
call our Technical Service Hotline at 800-231-517
Choose an eye-level spot in an indoor location, within six feet (I.8 m) of a
standard
I20 volt AC electrical outlet (or 240 volt outlet if timer is labeled as
such).The location should be completely protected from moisture, direct sun-
light and freezing temperatures.
*Do not use an outlet controlled by an on/off wall switch
*Do not use the same circuit as a garage door opener, washer,
dryer, air conditioner, refrigerator or other high-powered
equipment
*Do not place timer in a location where it can get wet
*Do not operate at temperatures exceeding 125°F (52°C)
CAUTION: This timer is designed for indoor installation only. Installing
this timer outdoors will void the warranty and may result in an electric
shock hazard.
Drive one of the two #8 Phillips screws provided into the stud or wall at eye
level, leaving 1/8”-1/4” (3.2-6.4 mm) of the screw head extended from the wall. If
mounting on drywall or masonry wall, plastic anchors may be required.
Hang the controller on the screw by placing the keyhole on the back of
the timer over the extended screw head. (Figure
I)
Lift the terminal cover and drive the second screw through the bottom
mounting hole into the wall.
CAUTION: Do not plug in the transformer until you have made
all
wiring connections.
Figure I
Connect a 9 volt alkaline battery (not included) to the battery terminal and
place in designated spot.
CAUTION:
Do not use a rechargeable battery. Do not allow the bat-
tery to come in contact with the screws in
the terminal strip.
The display will illuminate under normal conditions and 12:OO AM will
appear. If any unexpected display characters show, simply disconnect and
reconnect the
battery.You can now program your timer, even before you plug it
in. (You should not plug in the transformer until all valves have been connected.)
The battery operates as memory backup in the event of a power
outage, preserving your schedules for up to 24 hours. However, the timer will
not operate the valves while under battery
power. Watering will occur only after
power resumes.
Your timer also comes with a default mode. Should the battery fail
during a power outage, the timer will automatically revert to a preset factory
program, which will become active when the power comes back on, and will
water every day at 4:00 a.m. for IO minutes per valve, until a new schedule is
programmed.

We suggest you replace the battery once a year. When replacing the
battery, be sure not to unplug the transformer, or you will lose your
programmed schedules.
CAUTION: Do not plug in the transformer until all valves have been
connected.
Each valve has two wires. One wire is connected as the “common”
wire.The common wire for all of the valves should be spliced together to
become a single wire that will connect to the terminal screw labeled “C”. Back
the terminal screw out until the head is 1/8” (3.2 mm) above the surface.
Expose only 3/8” (I 0 mm) of bare copper from the end of the wire to reduce
short-circuiting of two adjacent wires, slip under screw head, and tighten.
The second wire is the “lead” wire. Connect the lead wire from each
valve to one of the terminal screws numbered l-6, depending on the number of
valves you’re using. Connect wire from valve I to terminal screw I, from valve 2
to terminal screw 2. and so on. (Figure 2)
CAUTION: Wire only one valve to each terminal screw. Wiring more
than one valve per terminal may result in damage to the timer. Do not
use valves that exceed maximum output holding current (0.25 amps}.
Also, fusing more than one timer, do not share common wires. Run a
separate common wire for each timer.
AC AC c 1 2 3 4 5 5
Lift the terminal cover and locate the two terminal screws labeled “AC”. Make
sure the transformer is not plugged in.
Insert power leads from the transformer under each of the two
terminal screws and tighten. (Figure 3)
Plug in transformer.
12:00 AM will be displayed.
CAUTION: Use with supplied transformer only. Do not plug in the
transformer until you have completed and checked all wiring connec-
tions. Do not link two or more timers together with a single transformer.
Always check local plumbing and electrical codes for requirements
when installing timer, transformer and sprinkling system. Use only with
appropriate transformer that matches your household voltage and plug type.

A program is simply your instructions to the timer, telling it which areas you
want watered on which days, at what time and for how long.
In general, when programming the timer, numbers or text will be
flashing on the display.The +/ON and -/OFF buttons will change the flashing
item. Holding down the +/ON or -/OFF buttons for longer than one second will
cause the timer to rapidly scroll through the digits.This allows for faster setting
of all items.Pushing the NEXT button will enter the flashing digit(s) and will
move you to the next program step.
If a programming button
(e.g.,TIME/DATE,WATER DAYS, etc.) is
pressed at any time during that programming sequence, the controller will take
you back to the beginning of that sequence.
I. PressTIME/DATE.The hour, minutes and AM or PM will flash.
2. Press +/ON or -/OFF to change to the current time. Press NEXT
to enter the time.
3. Year will be flashing. Press +/ON or -/OFF to change to the
current year. Press NEXT to enter the year.

4. Month will be flashing. Press +/ON or -/OFF to change to the
current month. Press NEXT to enter the month.
5. Date will be flashing. Press +/ON or -/OFF to change to the
current date. Press NEXT to enter the date.

to the current day of the week. Press NEXT to enter the day of the
week and move to the RUN mode.
The current time will now be displayed.
You have three choices in deciding on how often to water your lawn.
*Specific days of the week, e.g.,
MON.WED and FRI
*All ODD days
*All EVEN days
Only one of the three, either specific days of the week, odd days or
even days, will be valid at any one time. Selecting one option will disable the
other two.
1. Press WATER DAYS. SUN On or SUN OF (abbreviation for off) will
be displayed and either On or OF will flash. If SUN -- is displayed,
either the ODD or EVEN days schedule is programmed, and you will
not be able to program specific days of the week watering. If you
want to program days of the week watering, turn off ODD or EVEN
by following steps 2 through 8.
2. Press
+/ON or -/OFF to turn watering for that day on or off.
Press NEXT to enter the data and advance to the next day of the
week.
3. Repeat step 2 to turn on or off the remainder of the days of the
week for specific days of the week watering.
4. After SAT, ODD On or ODD OF will be displayed and either On
or OF will flash.
5. Press +/ON or -/OFF to turn ODD watering on or off. In ODD
days programming, the 3 I st of any month and the 29th of February in
a leap year are considered as OFF
6. Press NEXT to enter data and advance to the next step. EVN On
or EVN OF will be displayed and either On or OF will flash.
7. Press +/ON or -/OFF to turn EVEN watering on or off.
8. After pressing NEXT for the last time, the controller will move to
the RUN mode.
The current time will be displayed.
Your
RJ6 timer allows you to program up to three watering cycles per day.You
can activate all three, or you can leave one or two OFF Extra start times are
needed only if you wish to water more than once a day, e.g., for a new lawn or
in very hot weather.
I. Press START TIMES. Start time I (1))
will be displayed and the start
time currently set will be flashing. If there is no start time entered for
+/ON or -/OFF to set the first watering start time. Be sure
OFF position is between
I I:59 p.m. and
I2:OO a.m. Press NEXT to enter the start time and advance to
3. Repeat step 2 for programming start times 2 and 3.
4. After pressing NEXT for the last time, the controller will move to
the RUN mode.
The current time will be displayed
TIP:
The recommended time to water your landscape is in the early morning hours
(4 a.m.
- 7 a.m.), when evaporation and wind factors are minimal and when water
pressure may be better. Mid-morning through late afternoon hours usually have higher
evaporation rates, and late evening hours can create a fungus or mildew problem.
Your RJ6 timer allows you to set the watering duration of each zone for
a different length of time, from I minute to 99 minutes, in I minute increments. For
example, you might program Zone I (e.g., your front lawn) to water for IO minutes
and Zone 2 (e.g.. your flower bed) to water for 5 minutes at each start time.

I. Press RUN TIMES.Valve I (VI) will be displayed and iks run time in
minutes will flash. If there is no run time for valve I, OF will flash.
2. Press +/ON or -/OFF to adjust the length of time in minutes that
you want the valve to run. If you want to turn off the valve, set the
time for 00 minutes.The valve number and OF will be displayed.
Press NEXT to enter the data and advance to the next valve.
3. Repeat step 2 for valves 2 through 6
4. After pressing NEXT for the last time, the timer will move to the
RUN mode.
The current time will be displayed.
In the RUN mode, the timer will automatically water the programmed
schedules.
During a watering cycle, the valve number and run time in minutes
(e.g.,Vl: I5 min) will be displayed until the watering time has counted down to
00. After the last valve has completed its watering cycle, the current time will
once again be displayed.
During operation, you will notice a five-second delay between the
time one valve shuts and the next valve opens.This is to prevent water pressure
damage to your system.
You can turn off watering during rainy periods, or anytime watering is not
required, without losing your programmed watering schedules. If you press
-/OFF while watering is in progress, you will cancel the watering cycle in
operation
at that time only. Watering will resume at the next start time. If you
press -/OFF a second time, you will then place the timer in the RAIN OFF
mode and all programmed start times will be suspended.
To manually turn off watering when the timer is not running a
watering cycle:
I. Press -/OFF. OFF will be flashing.
2. Press +/ON to return to RUN mode and resume your normal
watering schedule.
You can manually water any zone at any time when extra watering is required,
e.g., during especially hot or dry weather.
Press MANUAL START. (VI : OF)will be displayed with the valve
run time (OF) flashing.
2. Press +/ON or -/OFF to set the number of minutes you want the
valve to water. If you don’t want a valve to water, set the run time to
00 minutes. Press NEXT to enter the data and advance to the next
valve.
3. Repeat step 2 to manually turn on valves 2 through 6 (valves will
be turned on in sequence).
4. After valves have completed their watering run time, the
controller will revert back to the RUN mode.
The current time will be displayed.
To stop MANUAL START during its cycle, press -/OFFWatering will
stop, and the timer will revert back to the RUN mode.
If there is a power outage and you have either no battery or a dead battery in
the timer, the timer will automatically revert to the default program when
power
resumes.With the default program, each zone will be watered for IO
I
minutes every day, starting at 400 a.m., until a new schedule is programmed.
The RJ6 timer is equipped with an electronic fuse which will identify a shorted
valve, turn off the valve control circuit on the shorted valve, and proceed with
the next valve.At the end of the watering cycle, the display will not revert to
showing the current time, but will display the word BAD, followed by the valve
number of the shorted valve.
Once the valve has been repaired (be sure to unplug the transformer
when repairing the valve), plug the transformer back in, press any key, and a nor-
mal display will reappear. If a scheduled watering time comes up before a bad
valve can be repaired, your regular automatic program will start, and the timer
will continue to bypass the shorted valve.
