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).

turn the dial to the “System Test or Run Single Station” position.
THE DISPLAY WILL SHOW:
The default run time for a single station is 10 minutes.
Advance to the selected station by pressing as many
times as required, and adjust the run time with or .
The controller will start running the selected station and the run time will decrement in the display.
If there is an active pump set for this station, the pump icon will flash once the button has been
pressed, indicating that the pump/master is running. As soon as the single station run time has
elapsed, the unit will revert back to automatic mode. This means that if you forget to turn the dial
back to the “Run” position, the controller will still run its automatic starts, as scheduled. To turn the
station off, change the position of the main dial, to “OFF”.
HINT: If you wish to alter the default value from 10 mins to some other value and set this as the new default
time. Turn the dial to “Run Single Station” press the button. Then alter the run time using the
or buttons. Once the new default time is set press the
button again, and the new default will
now always appear when you select a “manual single station”.
RUN A SYSTEM TEST
To manually run a system test turn the dial to the “System Test or Run Single Station” position, press
and together.
THE DISPLAY WILL SHOW:
The default run time for a single station is 2 minutes.
If you wish to alter the run time for this start only,
use the or buttons. Once the correct run time has been entered, turn the station
on and make it run by pressing the button.

12
MANUAL OPERATIONS
The controller will start running all stations with the selected run time. The time will decrement in
the display and will sequentially move through all stations, running them for the same set period of
time. This option is designed so that it is possible to test all sprinklers and valves that make up the
irrigation design.
To skip to the next station press the button. To go back a station press the button. To stop
the system test, change the position of the main dial, to “OFF”.
HINT: If you wish to alter the default value from 2 mins to some other value and set this as the new
default time, press the and together followed by button. Then alter the run time using
the or buttons. Once the new default time is set press the button again, and the new
default will now always appear when you select a “manual system test”.
RUN A PROGRAM
To manually run a complete program or to stack multiple programs to run, rotate the dial
to “Run Program”. The word “OFF” will be flashing.
THE DISPLAY WILL SHOW:
To enable program 1 to start press the button.
The icon “OFF” will change to “ON”.
This program has now been enabled so that it can be
run. To make program 1 run, press the
button.
NOTE: So long as there are run times in program 1 then program 1 will start and water the stations
associated with it.

13
There may be times when it is desirable to run more than one program manually. The controller
allows this to occur using its unique feature of enabling a program, before running it. For example
if you wish to run Program 1 and also Program 2, the controller will manage stacking of the programs
so they do not overlap.
Enable program 1 by pressing the button. To select the next program press
the button, the program number will increment to program 2.
Enable program 2 to run by pressing the button.
NOTE: To disable a program number, press the button.
Once both programs have been enabled, they can be run by pressing the button. The controller
will now run all programs that have been enabled starting with the highest numbered program.
So in this case, program 2 would run and when it has completed its cycle, program 1 would start
and run its cycle.
This method can be used to enable any, or all of the available programs on the controller.
NOTE: When running programs in manual mode the “Budget %” will alter the running times of each
individual station.
MANUAL OPERATIONS

14
MANUAL OPERATIONS
STOP WATERING
To stop an automatic or manual watering schedule, turn the dial to the “OFF” position.
NOTE: For automatic watering remember to turn the dial back to the “Auto Run” position, as “OFF” will
stop any future watering cycles from occurring.
STACKING START TIMES
Should you accidentally set the same watering start time on more than one program, the controller
will “stack” them in sequential order. All programmed start times will be watered from the highest
number first.
AUTOMATIC BACKUP
This product has permanent memory. This allows the controller to hold all stored values even in the
absence of power sources, which means that programmed information will never be lost. Using a
9 volt battery will keep the real time clock running during power outages. However, if the battery is
not used the real time clock is backed up every 10 minutes to the non volatile memory. This means
that when the power returns the clock will be restored to its last known value.
It is recommended that the battery is replaced every 12 months.
A low battery icon will light when the battery has a week left to run. When this occurs, replace the
battery as soon as possible so that the clock is maintained correctly during power failures.

OTHER FEATURES
RAIN SENSOR
When installing a rain sensor, first remove the the factory
fitted link between the “C” and “R” terminals shown here
by the wire.
Replace with the two wires from the rain sensor into these
terminals, polarity NOT required. Move the rain sensor
switch on the fascia to “ON”.
Turn the dial to “Set Auxiliaries” to enable individual
stations to be set rain sensor “ON” or “OFF”.
THE DISPLAY WILL SHOW:
Rain sensor installation

16
OTHER FEATURES
RAIN SENSOR (CONT.)
If a station is turned “ON” this means that the sensor will control it, should it rain. The default mode
is for all stations to be rain sensor “ON”. Should you have a station (valve) that always needs to be
watered, e.g. an enclosed green house or plants that are under cover, then the rain sensor can be
turned “OFF” for these particular stations. To select a station to turn “OFF”. Press the button,
the word “ON” will now be flashing, use the button to change to “OFF”.
TIP: To turn the station back “ON” press the button. To advance to the next station use
the button and the station number will increase. Do this operation for all stations (valves)
on the controller that need to be altered.
HINT: To disable the rain sensor and allow all stations to water regardless of the setting, move the slide
switch marked Rain/Sensor to the “OFF” position. The reactivate it slide the switch to the “ON” position.
RAIN DELAY
Different rain sensors react in different ways. The most common complaint about rain sensors,
is that they dry out too quickly, and allow the system to come on within hours of a rain storm. To
counter this problem the controller has a “Rain Delay” setting that allows a specific delay time to
elapse after the rain switch has dried out before the controller will water again. Turn the dial to the
“Set Auxiliaries” position. Then press the button. The rain delay value will now be flashing.
THE DISPLAY WILL SHOW:
Press the button to alter the rain delay time in
increments of 12 hours at a time.
A maximum delay of 240 hours or 10 days can be set.
STOP ALL WATERING
To stop all watering cycles during winter, turn the dial to the “OFF” position.
The display will show “ALL OFF”:

17
This means that all automatic schedules will not come on,
but the programmed information is still retained in the memory
and the clock still keeps track of time even though it is no
longer being displayed.
To reactivate watering, turn the dial to the “Auto Run” position.
WATER BUDGETING & SEASONAL ADJUSTMENT
The automatic station run times can be adjusted by percentage as the seasons change. This will save
valuable water as the run times can be adjusted quickly in spring, summer, and autumn to reduce or
increase water usage.
Ensure the dial is in the “Auto Run” position.
Press the button.
THE DISPLAY WILL SHOW:
This means that the run times are set to 100%, i.e. if station 1 is set to 10 minutes then it will run
for 10 minutes. For example, should the value change to 50% then instead of running for 10 minutes
station 1 would now run for 50% of 10 minutes, i.e. 5 minutes.
Conversely should the budget value be altered to show 200% then instead of running 10 minutes
on station 1, it would run for 20 minutes. The budget calculation is applied to all stations and all run
times that are active.
To increase the budget percentage press the , to decrease the budget percentage press the
. The percentage value will increment or decrement in multiples of 10%. The maximum value
is 200% and the minimum value is 10%.
To return to the clock display press the button.
Should the budget value no longer be 100% then it will be shown
in the clock display, e.g. if we set the budget to 200%.
