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.

Programming Instructions

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).

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.

General tips for easy programming

Tips to help eliminate programming confusion.

l Complete the spare watering planner.
l When setting, one push of the button will increment

one unit.

l Holding one button down will fast scroll through units.
l During programming, flashing units are able to be set,

Programming Example

A typical example of a 8 station system is included on the
following page as a guide to assist you when planning
your watering schedule.

In this example, the lawn areas are using pop-ups and
require less frequent watering.

The vegetables are being watered using drippers, and
the flower beds and pergola areas are being watered
with micro sprays.
