Thank you for selecting an Orbit® sprinkler Timer. Orbit® designers have
combined the simplicity of mechanical switches with the accuracy of digital
electronics to give you a Timer that is both easy to program and extremely
®
versatile. The Orbit Timer provides convenience and flexibility, letting you
run a fully automatic, semi-automatic, or a manual watering program for all
your watering needs.
Please read this manual completely before you begin to program and use the
controller. A few of the most notable design features include:
At-a-Glance Simplicity
By turning the rotary dial to one of nine settings you can review program-
ming or easily make changes.
Arm Chair Programmable
By inserting two AA alkaline batteries you can program the Timer prior to
installing it in its permanent location.
Fail-Safe Program / Non-Volatile Program Memory
If the Timer loses AC power, the existing program will not be lost. After the
AC power returns, the Timer will recall the last program into memory and
there will be no need to re-program. If both the AC power is lost and the
batteries are dead or missing, the user will only need to reset the time and
date; all other program settings are held in non-volatile memory, and there is
no need for re-entry.
Fuse
Red flashing LED indicates blown fuse. The 0.75 amp slow-blow fuse pro-
vides circuit protection. For replacement, use WaterMaster 0.75 amp fuse or
equivalent.
Lexan Language Covers
Available in English, French, Spanish, Italian, German.

Introduction

1. Digital Display
A large LCD (Liquid Crystal Display) shows the time of day and indicates
many of the programming settings. The display is completely interactive
with all other controls.
2. Programming Keys
The Timer has seven push button keys for setup and program entry.
Working in conjunction with the rotary selector, the keys are used to set the
time of day, watering time, watering days, start times, and other functions.
3. Selector Dial
This large dial makes it easy to see which function is currently selected
and/or in which mode the Timer is set to operate.
4. Reset Button
The reset button clears the time, date and user-defined programming but does not
remove the factory installed fail-safe program. To prevent an accidental reset, the
button is recessed into the panel and must be pressed with a small pointed object
such as a pen or pencil tip.
Notable Programming Features
Two Watering Programs—Summary
The Timer gives you the option of using one or both of the independent pro-
grams. Note that each station can independently be set to either A or B or
both A and B programs.
Program–A
This program lets you schedule selected stations to water on specific days of
the week or to water every 2nd day. Program A repeats itself continuously in
successive weeks.
Program–B
Provides two options: One for odd or even day watering or for intervals rang-
ing from everyday to every 28th day. This feature is designed to meet the
growing needs and restrictions imposed by local governments and to con-
serve water. The Timer automatically calculates odd and even days (by date)
for each month and makes adjustments for leap years to provide true odd
and even watering through the year 2095.
Start-Time Stacking
2nd
The Timer has the intelligence to "stack" start times that overlap.

INTERVAL
ODD
If you enter two or more start times that overlap (in the same or in different
EVEN
programs), the Timer will not activate two stations at the same time. Instead,

DURATION
The Timer will NOT stack to the next calendar day. This prevents the Timer
