Section 1: Introduction

Thank you for selecting an Orbit® sprinkler timer. Orbit® designers
have combined the simplicity and 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, a semi-automatic, or a manual watering pro­gram for all your watering needs.

Please read the manual completely before you install or use this
sprinkler timer.

To assist you, we have included some notable features to
this manual.

1. Glossary of the most common terms (see page 17)

2. Blue Text relates to the buttons used for programming

3. Blue Underlined Text relates to stop positions for both
rotary dial and slide switches.

Programming Features

Dual Programs

This Timer has two programs (“Program A” and “Program B”)
that allow you to set up separate watering schedules for your Lawn,
Gardens or Shrubs.

Fail-Safe Program

If the timer loses AC power, the existing program, date and time will
not be lost. After the AC power returns, the timer will recall the last
program into memory. If both the AC power is lost and the battery
is dead or missing, the user will have to reprogram the timer.

Water Budgeting

This feature is ideal when adjusting to seasonal watering demands.
Instead of reprogramming your timer, the “Water Budget Mode” will
enable easy adjustments to watering duration by ten percent incre­ments from 10%-200%. For example, a budget percentage set at
70% will alter a 10-minute preset watering duration to 7 minutes.

Start-Time Stacking

When a start time is set before the previous program has completed,
that start time will be “stacked” or delayed, and will start upon
completion of the previous program.

Section 2: Getting Started

Programming the timer can be accomplished in just a few basic
steps. Before you begin programming, it is important to install the
battery, set the time of day and date, and establish a watering plan.

To activate battery, pull the narrow black plastic strip out, this
is protruding out the top panel.

Replacing the Battery

The timer requires one CR2032 Lithium battery to keep the program
in memory in case of AC power loss. In a typical installation, the
battery should provide sufficient power for approximately one year
of protection. Therefore, we recommend changing the battery every
year.

• Remove the battery cover by sliding it upward.

• Insert one CR2032 battery into the battery compartment.

• Return the battery cover to its closed position.

A weak or missing battery can cause the time, date, and program
to be erased after a power failure. If this happens, you will need to
install a fully charged battery and reprogram the timer.

Note: A battery alone will not operate the valves in your sprinkling
system. The sprinkler timer has a build-in transformer that must be con­nected to an AC line voltage source.

Resetting the Sprinkler Timer

If this is the first time the sprinkler timer has been programmed, you
should press the small recessed button labeled RESET. Do not press

Note: If a watering schedule is not entered into the timer, the factory
installed fail-safe program will turn on each station every day for 10 min­utes. To avoid accidental station activation, either turn the rotary switch
to off or enter a watering schedule.

Determine a Watering Plan

To help you visualize how best to program the sprinkler timer, it
might be helpful to make a watering plan on paper. This will help
you establish which days and times you want to water. [See Figure 2]

1. For each station (or valve) write down the watering location,
the type of sprinkler head and the plants to be watered.

2. Using this list, determine the recommended watering dura-
tion (for each type of sprinkler head and the vegetation
to be watered) and frequency for each station.

Important: Identify any imposed watering restrictions through
your local water district.

3. Determine, based on step 2, the ideal watering option for each
station.

• Program A allows you to select specific days of the week to
water (e.g. Monday, Wednesday and and Saturday) as well
as every second day (every other day).

• Program B allows you to specify 2 options:

- Interval Watering - Interval watering is used to water at

an interval from 1 to 28 days. An interval of 1 will water
every day; an interval of 2 will water every other day, etc.

- Odd or Even Days - The sprinkler timer can be selected

to only water on Odd days or Even days. The odd/even
schedule is based on the date.

appears under “M” and the cursor will advance to Tuesday
(“T”), press ENTER to activate watering on Tuesday or NEXT
to skip to the next day. [See Figure 5] Repeat these steps for all
days of the week.

• To delete a previously entered day, press CLEAR.

• If you want to water every second day, press the NEXT key to

advance the cursor to “2nd”, then press ENTER. If you choose
to water every 2nd day, you cannot set specific days of the
week for watering.

Please proceed to the “Automatic Operation” section if a Program
B is not required.

Program B - Interval Watering & Odd and
Even Days

STEP 1. SET THE “START TIME(s)”

Note: The cycle start time is the time the program begins watering the
first station. Cycle start times do not correspond to specific stations.

• Turn the dial to the CYCLE START TIMES position in

“Program B”. The display will show a “B” and a blinking
cursor should be next to “Cycle Start Time 1” (on the left side
of the LCD). If not, push the NEXT key until the curser is
next to “Cycle Start Time 1”.

• Set the time you want to begin watering for start time 1 using

the or keys, then press the ENTER key. The curser

2. Mounting the Sprinkler Timer

• Use the mounting template (included) to mark the screw
locations on the wall.

• Insert a No. 8 screw (included) in the upper mark, leaving
the screw head about 1/8” (3mm) out from the wall. (Use the

expanding anchors in plaster or masonry if necessary.)

• Slip the keyhole slot in the back of the sprinkler timer over the

extended screw. [See Figure 12b]

• Screw a No. 8 screw through the hole located behind the wire

shroud cover.

3. Install the Batteries

One Lithium battery (CR2032) is required to retain the program in
memory during power loss. Annual replacement is recommended.

• See page 3 for battery replacement

Note: The battery alone will not operate the valves in your sprinkling
system. The sprinkler timer has a build-in transformer that must be con­nected to an AC line voltage source.

4. Wiring 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 (usually white)

[See Figure 13]

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.

• To avoid electrical hazards, only one valve should be connected

to each station.

Important: The wire can be buried in the ground; however, for more
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 digging or trenching in the future.

ENGLISH

INSTALLATION USING PERMANENT WIRING

Important: The sprinkler timer has a built-in transformer that must

be connected to an AC line voltage source. Check the back of the
sprinkler timer box for power requirements. Local building and elec­trical codes usually require that an approved electrical conduit and
electrical fittings be used to connect exterior wall-mounted equipment
to AC power. Please check local codes. Any permanent connection
should be made by a licensed electrical contractor in accordance with
the requirements of the National Electrical Code and other state and
local codes.

Caution: Do not connect the sprinkler timer to one phase of a three phase
power system used by a pump or other electrical equipment.

Important: This sprinkler timer has a ¾” knock-out. Use a ¾” (13mm)
waterproof connector to connect the sprinkler timer to a standard electri­cal junction box. Both connector and junction box must be UL Listed or
equivalent or comply with IEC or EN standards or equivalent.

• Turn off the AC power at the AC circuit breaker and apply
an appropriate safety lockout. Verify that the power has been
turned off to the installation site using an AC voltmeter set for
the correct measurement range.

• Use power feed wire of 14 gauge (AWG) minimum with a

temperature rating of 155 degrees Fahrenheit (68 degrees
Celsius) or higher.

• Install the conduit and associated fittings. Connect the AC
electrical power wiring to the source by following all the right
codes and local standards.

• Connect the junction box and 3/4” Connector to the Timer
(Junction box and Connector not included). [See Figure 15]

• Connect the source power conduit to the entrance of the junc­tion box, following all the appropriate codes.

• Take the cord (running from the timer to the junction box)
from the junction box and cut it to length. Remove the outer
insulation (from cord) to expose the three wires.

• Connect the source wires to the wires extending from the
sprinkler timer.

• Take care to follow the correct color code. For USA: connect

the Green for Ground, Black for Live, and White for Neutral.
Often the source ground may be bare copper conductor rather
than green wire. For Europe: Live is Brown and Neutral is
Blue, there is no ground connection required. Be sure that all
wires are connected to the proper source wire.

• Make sure all connections are made with code-approved insu­lated connectors.

• Be sure to place a weatherproof gasket and lid on the junction
box.

• Turn AC power on at the AC circuit breaker.

Appendix A: Connecting to a Rain Sensor,

Pump Start or Master Valve

Rain Sensor and the Rain Sensor Bypass
Switch (sensor sold separately)

A rain sensor or other type of micro-switch weather sensor may be
connected to the sprinkler timer. The purpose of the sensor is to
stop watering when precipitation is sufficient.

CONNECTING A RAIN SENSOR

• Connect the rain sensor wires to the wiring terminal ports

(beige in color) labeled “Sensor” [See Figure A1]

Note: Refer to your rain sensor manual for specific wiring instruc-
tions.

• Place the sensor on/off switch to the “on” position to begin

operation.

RAIN SENSOR BYPASS

This sprinkler timer is equipped with a sensor override “on/off”
switch. This switch is for use during maintenance and repairs, so the
sprinkler timer can be operated even if the rain sensor is in active
mode.

IMPORTANT: If the rain sensor switch is in the “on” position and no sen-
sor is connected, the sprinkler timer will not operate. To resume sprinkler
timer operation place the switch in the off position

PUMP START & MASTER VALVE

This sprinkler 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” terminal and the other wire to the “Common” terminal. [See
Figure A2]
