FEATURES
This unit is available in 4 & 6 station configurations Designed for
residential applications, this controller has four separate programs
with a maximum of sixteen start times a day. This ensures efficient
watering of different garden or turf areas.
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, flower beds use 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 three types of watering day options. Either, interval
watering from everyday to every 15th day, individual day selection per
program, or a 365 day calendar for ODD/EVEN day watering.
An innovative feature of this controller is the water saver feature which
allows quick adjustment of the station watering times by percentage
as the seasons change Another water saving feature is the installation
of a rain sensor. This controller has a rain sensor switch in the fascia
so your can enable or disable the rain sensor control function.

INTRODUCTION
This controller has been designed with four separate program starts,
to allow different garden areas to have their own individual watering
requirements.
A start 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 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.
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 start.
Use the following 3 steps to program 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).
