Features
This unit is available in four, six and eight station
configurations.
Designed for residential and light commercial
applications, this controller has two separate schedules
with up to eight start times a day to ensure efficient
watering of different garden or turf areas.
These different areas may require individual watering
schedules and often use different types of sprinklers.
Examples: Turf areas generally use pop-up sprinklers
and require less frequent but heavier watering. However,
flower beds use micro sprays and require more frequent
watering. The valves (stations) which water similar
garden areas are often grouped together and put into the
same program as they need to be watered on the same
days.
These stations (valves) will water in sequential order
from the lowest number at the start time (or times)
nominated and on the days selected. Maximum watering
duration for a station (valve) is 12 hours and 59 minutes.
This 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 everyday to every 15th day.
A key feature of this controller is the water saver feature
which allows quick adjustment of the station watering
times by percentages as the seasons change.

Introduction
This controller has been designed with two separate
programs to allow the different garden areas to have their
own individual watering schedules.
A program is basically a method of grouping stations
(valves) with similar watering requirements to water on
the same days. These stations will water in sequential
order from the lowest number at the start time (or times)
nominated and on the days selected.
The important elements of programming your
controller are:
l Group the stations (valves) which are watering similar
garden areas together.
Examples: Turf, flower beds, pergola areas, vegetables.
These different groups may require individual watering
schedules.
l Plan your watering schedule and write the information
on the planner supplied at the back of this book.
l Set the current time and correct day of the week.
l Set the automatic program for each group by
completing the following 3 steps.
1 Set Starts.
This sets the time when the watering schedule is to
commence.
2 Set Watering Days.
These are the nominated days when the
automatic system will be active.
3 Set Station Run Times.
This sets the watering duration required for each
station (valve).

Programming Instructions
Other Functions
This controller can also manually run a selected program
once, or an individual station can be set to run once from
1 minute up to 12 hours and 59 minutes. During winter
the automatic schedules can be suspended to prevent
watering while it is raining. A test facility for checking the
valves and sprinklers is also provided.

Do not attempt to drive a pump starter directly from the
controller. Pump start is provided by connecting one side
of the coil of a suitable relay to the Master Valve/Pump
Start output of the controller and the other side to the
controller common.
For systems supplied with water from a Pump, unused
stations must be connected back to the last used station
to eliminate the possibilty of the pump running against a
closed head. Failure to do so could lead to pump
damage.
