RPS469 is available in 4, 6 and 9 station configurations. Designed to cover a wide range of
applications from residential and commercial turf, to light agriculture, and professional nursery.
This controller has a possible 6 separate programs with up to 36 starts per day. The controller has
a 7 day watering schedule with individual day selection per program or a 365 calendar for odd/even
day watering or selectable interval watering schedules from every day to every 15th day. Individual
stations can be allocated to one or all programs and can have a run time of 1 minute to 12 hours 59
minutes or 25 hours if the water budget is set to 200%.
K-Rain has always been concerned with sustainable water usage. The controller has many water
saving features that can be used to maintain the highest standard of plant quality with the least
amount of water consumption. The integrated budget facility allows global changes of run times
without affecting programmed run times. This allows for decreasing total water consumption on days
of minimal evaporation.

PROGRAMMING INSTRUCTIONS
INTRODUCTION
This controller has been designed with 6 separate programs to allow different landscape areas to
have their own individual watering schedules. A program is a method of grouping stations (valves)
with similar watering requirements to water on the same days. These stations will water
in sequential order and on the days selected.
Group the stations (valves) which are watering similar landscape areas together.
Examples: Turf, flower beds, gardens. These different groups may require individual
watering schedules, or programs.
Plan your watering schedule completing the planner supplied at the back of this book.
Set the current time and correct day of the week. If odd or even day watering is going to be
used, make sure the current year, month and day of the month is correct.
HINT: To select a different program use the button marked
.
Each press will move to the next
program number. This is handy for quick reviewing of previously entered information without losing your
place in the programming cycle.
SET AUTOMATIC PROGRAM
Set the automatic program for each group of stations (valves) by completing the
following three steps:
1. Set start times
This sets the time when the watering schedule is to commence.
NOTE: For each start time, all the stations (valves) selected for the program will come
on in sequential order. If two start times are set, the stations (valves) will come on twice.
2. Set Watering Days
These are the selected days when the automatic system will be active.
3. Set Station Run Times
This sets the watering duration required for each station (valve).

STEP 2 – SET WATERING DAYS
This unit has interval watering from every day to every 15th day, individual day selection or a 365
day calendar with odd/even day selection in areas where water restrictions require this feature.
INDIVIDUAL DAY SELECTION

ODD/EVEN DAY SELECTION (OPTIONAL)
In some areas users are only allowed to water their landscapes on odd dates if their house number is
odd, or even dates when their house number is even.
This controller allows this to be done simply by setting the relevant selection of odd or even and
setting the current date into the controller. The controller will account for leap years.
If you require the odd/even day option, simply press the
button until
“Odd” is shown.
Press the
button and
“Even” will be shown.
This feature may be required in areas where water restrictions are enforced.

INTERVAL DAY SELECTION
Press the
button until the
“interval days” is flashing.
THE DISPLAY WILL SHOW:
“Interval 1” will be flashing. This means the controller will
water every day. The display will show how many days

the interval day, press the
or
button.
Select from 1 to 15 interval days.
NOTE: When changing the interval day, the next active day is always changed to 1. This means that
tomorrow is the first active day to run.
STEP 3 – STATION RUN TIMES
This is the length of time that each station (valve) is scheduled to water on a particular program.
Maximum watering time is 12 hours 59 minutes for each station.
A station can be assigned to any or all of the possible 6 programs, if required.
Turn the dial to the
“Set Station Run Times” position.
THE DISPLAY WILL SHOW:
NOTE: This means that station 1 of program
1 has no run time programmed in it. The controller
has permanent memory so when the device is first used
there will be no run times set. Unlike other controllers,
when there is a power failure, even if the battery is not
installed, the programmed values will be restored to the unit.
