Section 1: Introduction

Thank you for selecting an Orbit® Signature Control timer,
the most advanced and versatile controller available. Orbit®
designers have combined the latest technological features with
an intuitive display to create a controller that ts every watering
need.

Please read this manual completely before you begin
programming and using the controller.

Important Features and Capabilities

Dual Programs

The timer offers two programs – Program A and Program B – for
watering exibility. Any of the watering stations can be assigned
to either program. For example, stations that water your garden
and ower beds could be assigned to Program A and watered
daily starting at 8 a.m., while stations that water your lawn could
be assigned to Program B and watered every third day starting at
5 a.m.

Six Cycle Start Times Per Program

The timer accommodates six different start times for each of the
two programs (A and B). Most timers only allow four different
cycle start times.

No-Watering Days and Times

It’s easy to prevent watering on one or more days of the week
or during specic periods of the day. This comes in handy if
watering restrictions are imposed in your area.

ENGLISH

Docking Port

This timer has been designed for convenience and “armchair”
programming. The timer’s docking port is mounted on a wall
and all wires are connected to it. The main timer unit can be
easily and quickly slid on and off the docking port, allowing
you to take the timer virtually anywhere to create or change
watering programs.

Remote Control Capabilities (Not included on all models)

This timer can be controlled by the included remote control
device via a radio frequency (RF) receiver and antennae, both
of which are built into the timer. The remote control device
allows you to turn stations on and off on the spot and to
perform programming tasks from anywhere within range. The
433 megahertz remote frequency is approved for use in the
United States, Canada, Europe and Australia, and permits an
effective line-of-sight range of 300 feet (reduced to 200 feet
with obstructions).

Programming Information Stored Safely
in Non-Volatile Memory

All programming information for Program A and Program
B is stored indenitely in the timer’s non-volatile memory
(EEPROM) and internal memory. This high-end feature means
your programming won’t be lost or erased if the power and
batteries go out.

Easy-to-Read Back-Lit LCD Display

The timer’s back-lit blue LCD display screen is easy to read
under any lighting conditions.

Choice of Five Languages

You can easily set the LCD display to read in any of ve
languages: English, Spanish, French, German or Italian.

Water Budgeting

This convenient feature provides a quick, easy way to increase
or decrease the watering durations of all stations in both
programs to match seasonal watering needs. You won’t have to
adjust each station’s watering time individually.

Rain Sensor (Optional)

An optional rain sensor can be purchased separately to prevent
programmed watering for a period of time after rain falls
(determined by the amount of rain and how quickly the
sensors dry out). If your unit is RF capable then you can use a
wireless sensor. Otherwise a hard-wired sensor can be used.

Commonly Used Controls

Digital Display with Text Messaging

A large LCD (Liquid Crystal Display) shows the time of day and
indicates many of the programming settings. Interactive text
messaging simplies programming and current sprinkler timer
status. (See Figure 1)

• Phillips screwdriver

• Wire strippers

Installing the Sprinkler Timer
in Five Easy Steps

1. Select a Location

Select a location with the following criteria:

• Near an electrical outlet. (Avoid using an outlet controlled
by a switch.)

• In a dry, indoor location, where operating temperatures
are not below 32° or above 122° Fahrenheit (below 0
degrees or above 50 degrees Celsius).

• Not in direct sunlight.

• Accessible to sprinkler wires from valves.

2. Mount the Docking Port

• Slide the timer off the docking port. (See Figure 3)

• Using the mounting template (included), mark the two

screw locations on the wall, then drill holes at the marks
for No. 8 screws. Use the expanding anchors in plaster or
masonry if necessary.

• Place the docking port against the wall, aligning the two
holes in the docking port with the two drilled holes.

• Secure the docking port to the wall by screwing a No. 8
screw (included) through each of the two holes.

• Do not slide the timer back onto the docking port yet.

3. Connect the Transformer

• Find the two sockets at the bottom of the docking port
labeled “24VAC.” (See Figure 4)

• Insuring the transformer is not plugged in; insert one of

the two power leads from the transformer into each
terminal socket using the phillips screwdriver to depress
the terminal button (this allows for wire insertion or
removal).

• Plug in the transformer.

WARNING: Do not link two or more sprinkler timers together with
one transformer.

4. Connect Valve Wires to Timer, Pump Start and Master
Valve Sockets

A. Wire the Electric Valves

NOTE: If the distance between the sprinkler timer and valves
is under 700’ (210 m), use Orbit® sprinkler wire or 20 gauge
(AWG) plastic jacketed thermostat wire to connect the sprinkler
timer to the valves. If the distance is over 700’ (210 m), use 16
gauge (AWG) wire.

• Taking the sprinkler wire, strip 1/2" (12 mm) of the
plastic insulation off the end of each individual wire.

• Connect one wire from each valve (it doesn’t matter
which wire) to a single “common” sprinkler wire. This
is usually white. (See Figure 5)

IMPORTANT: All wires should be joined together using wire
nuts, solder and/or vinyl tape. For additional protection to
waterproof connections, an Orbit® grease cap can be used.

• Next, connect the remaining wire from each valve to a
separate colored sprinkler wire.

Transformer

SENSOR COM PUMP

• To avoid electrical hazards, only one valve should be
connected to each station.

IMPORTANT: The wire can be buried in the ground. However,
for greater protection, wires can be pulled through PVC pipe
and buried underground. Be careful to avoid burying the wires
in locations where they could be damaged by future digging or
trenching.

B. Connect Valve Wires to the Sprinkler Timer

• Strip 1/4" (6 mm) of the plastic insulation off the end

of each wire.

• Determine which valve you want to connect to which

station. Insert each sprinkler wire, excluding the
“common” wire, into a separate station socket (num­ bered above each socket) by inserting the bare wire
fully into the socket under each number. (See Figure 5)

• Connect the common wire to one of the two sockets
(white in color) labeled “COM.”

NOTE: Insert only one wire into each “COM” socket. If more
than two common wires are required, splice several together so
only one wire runs into each of the two “COM” terminals. Protect
the splice connection with a wire nut.

C. Connect Pump Start and Master Valve

This timer allows a master valve or pump start relay to oper­ate whenever a station is on.

NOTE: If you are activating a pump from this timer, you must
purchase a Pump Start Relay.

From the pump start relay (or master valve); connect one
wire to the “PUMP” socket and the other wire to the “COM”
socket.

Once all connections to the docking port are made, you may
slide the timer back onto the docking port.

5. Mount the Sleeve for the Remote Control Device

• Using the mounting template (included) mark the two
screw locations on the wall, then drill holes at the marks
for No. 8 screws. Use the expanding anchors in plaster or
masonry if necessary. (The sleeve can be mounted any
where and does not need to be next to the timer.)

• Place the remote control device sleeve against the wall,
aligning the two holes in the sleeve with the two
drilled holes.

ENGLISH

• Secure the sleeve to the wall by screwing a No. 8 screw
(included) through each of the two holes.

• Slide the remote control device into the sleeve.

Section 7: Diagnostics Circuit Breaker

Smart-Scan® Diagnostic Fault Sensing

A diagnostic fault sensor will automatically scan for the
presence of a faulty solenoid or wiring short in a valve during
each watering sequence. If a faulty station is detected, the
sprinkler timer will move to the next working station. Smart­Scan® also detects faulty wiring for the Pump or Master Control.
Upon detection watering cycle is discontinued.

Fault Notification

• Faulty Station: “FAULT STN” and station number is
displayed. When multiple faulty stations are detected, only
the last faulty station will be displayed.

• Faulty wiring for pump/master control: “PUMP FAULT” is
displayed.

Correcting the Fault

1. First, repair the short in the wiring or replace the faulty
solenoid.

2. Test the station by operating a manual watering
sequence.

3. If the short is not detected after a few seconds, the fault
notication message will be terminated.

4. If the message continues, a short in the wiring still exists.

Internal Auto-Resetting Electronic Circuit Breaker

The sprinkler timer is equipped with an internal electronic
self-resetting circuit breaker.

Possible causes of a circuit breaker tripping:

1. If lightning strikes nearby.

2. When the power supply has an electric spike.

3. If a station has a wiring short.

Whenever one of these conditions occurs, the electronic circuit
breaker may trip, causing the station output from the sprinkler
timer to be halted momentarily. The batteries will continue
to activate the LCD. After a few moments, the sprinkler timer
will automatically retest the circuit to see if the condition has
stopped. If so, the circuit breaker will reset itself.

Section 8: Glossary of Terms

Determine a Watering Plan

Your timer has two programs: Program A and Program B. The
dual program capability allows you to assign certain water­ing stations to Program A and others to Program B. There are
various reasons why you would want to do so. For example,
you might want to assign the stations that water the garden and
ower beds to Program A and those that water the lawn areas
of your yard to Program B. That way, you can set Program A to
water the garden beds every day, and set Program B to water the
lawn every second or third day.

Your timer allows you to set up to six different watering cycle
start times for Program A or Program B. You cannot set a cycle
start time for each station. Stations can be assigned to either
Program A or Program B. Stations assigned to a program will turn
on sequentially according to the cycle start times assigned.

To help you visualize how best to program your timer, it might
be helpful to make a watering plan on paper. This will help you
establish the days, times and durations to water each station.
