Features
This unit is available in a 4 or 6 station conguration. Designed
for residential applications, this controller has four separate start
times and each can be programmed individually to suit your
watering needs.
These different areas may require individual watering programs
and often use different types of sprinklers.
Examples: Turf areas generally use pop-up sprinklers and require
less frequent but heavier watering. However, ower 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 start/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 calendar with individual day selection,
even, odd + odd-31 and interval days from 1 to 15.
A key water saving feature is the installation of a rain sensor. This
controller has a rain sensor switch in the fascia so you can enable
or disable the rain sensor control function.

Introduction
The key elements when programming your controller are:
1. Grouping the stations. (valves)
Group together garden areas which have similiar watering
requirements. Examples are: Turf Areas, Flower Beds, Pergola/
Undercover Areas, or Vegetables. These different groups require
individual settings (programs).
2. Planning out your watering program.
Complete your individual watering planner, supplied at the back of
this book.
3. Setting the current time and correct day of the week.
4. Setting an automatic program.
Use the following 3 steps to set each group.
4.1 Set Start(s).
This sets the time of the day when the watering program will
commence.
4.2 Set Watering Days.
These are the nominated days when the automatic system will
be active.
4.3 Set Station Run Times.
This sets the watering duration required for each station (valve).
Programming Instructions
This controller has been designed with four separate starts
(programming schedules), to allow different garden areas to have their
own individual watering requirements.
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 stations
can have different durations.

Programming Instructions
A typical 6 station system is illustrated below. This guide will assist you
when completing your watering planner. In this example the lawn areas
are using pop-up sprinklers & require less frequent watering.
The vegetables are watered using drippers, with a longer run time &
the ower beds/pergola areas are watered with micro spray nozzles.
Each area is put into a separate program.

Installation Instructions
Pump Hook-Up Connections
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!
The diagram shows an 6 station controller with 4 active stations (valves):
Unused stations must be
linked back to the last
used station.
Use insulated cable.
