Introduction

Programming
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.
The Timer has two programs you can setup to control a variety of watering schedules. Depending on your needs, you can use either or both programs.
The Orbit Timer has the ability to override the automatic program without disturbing the preset program.

Semi-Automatic & Manual Operation
Enter Watering Schedule in Any Order
Using the Semi-Automatic Mode
(All stations cycle once both A & B programs) Turn the rotary dial to AUTO, then press the MANUAL key. The display will show AB, MANUAL, and ALL will be blinking [See Figure 9]. This indicates all stations will semi-automatically water for their assigned durations in sequence. To activate the assigned water durations in the A and B programs for each station, press ENTER.
FIGURE 9: Semi-Automatic Watering for Stations Assigned to A and B
Please read this manual completely before you begin to program and use the controller. A few of the most notable design features include:
You have the option of entering your watering schedule in whatever order you like. This feature makes it very easy to review and change your watering schedule. Your settings can be changed at any time while youre setting up the initial schedule or even after years of operation.

At-a-Glance Simplicity

By turning the rotary dial to one of nine settings you can review programming or easily make changes.
Start Times for Program A or B
Note: A start time is the time of day that the program begins watering the first station, and all other stations in the program will then follow in sequence. There are not separate start times for each station. Start times do not correspond to specific stations, but to programs (A or B). If you enter more than one start time, all stations in the specified program will water again (in sequence). The way you set the cycle start time is the same for both programs. Turn the rotary dial to the CYCLE START TIMES position in the program that you want to set. The display will show an A or B depending on which program you have selected. The display will show : and a blinking cursor in CYCLE START 1 location [See Figure 4]. Set the time you want to begin watering for start time 1 using the + or keys, then press the ENTER key. The display will advance to START 2. For additional start times, simply repeat this procedure by using the + and keys to enter the time and then press ENTER. Remember, Each start time will activate all stations that are set to water in the specified program. There are not separate start times for each station. Start times do not correspond to specific stations. Up to four start times can be entered per program (A or B).

Arm Chair Programmable

By inserting two AA alkaline batteries you can program the Timer prior to installing it in its permanent location.
The 0.75 amp slow-blow fuse provides circuit protection. For replacement, use WaterMaster 0.75 amp fuse or equivalent.

Programs

Lexan Language Covers
Available in English, French, Spanish, Italian, German.

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.
Note: Water durations assigned to station 1 in program A will water first, then move to station 1 in program B before advancing to the second station and will continue alternating. Only those stations assigned a watering duration will water when using the manual or semi-automatic mode [See Figure 10].
FIGURE 10: Semi-Automatic Watering Entered for A and B Programs, All Stations

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.
FIGURE 1: Location of Controls on the Timer

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.
FIGURE 4: LCD Display with Start Time

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.
Water Duration for Program A or B
Note: Both programs require watering durations to be programmed. Turn the rotary dial to ZONE DURATION position in either the A or B program. The display will show which program you have selected with an "A" or "B" and the - - cursor blinking at station "1" [See Figure 5].
(All stations cycle once, A program only) To activate stations assigned watering duration for the A program only, press the MANUAL key, followed by the NEXT key. This will activate stations with assigned watering durations in the A program only. To initiate this semi-automatic watering, press ENTER [See Figure 11]. (All stations cycle once, B program only)

Notable Programming Features
Two Watering ProgramsSummary
The Timer gives you the option of using one or both of the independent programs. Note that each station can independently be set to either A or B or both A and B programs.
To activate stations assigned watering durations for the B program only, press the MANUAL key, followed by pressing the NEXT key two distinct times. This will activate only those stations with assigned watering durations in the B program only. To initiate this semi-automatic watering, press ENTER.
FIGURE 11: Manual Watering in Either the A or B Program Only

ProgramA

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.
FIGURE 5: Station Duration for Program A

ProgramB

Provides two options: One for odd or even day watering or for intervals ranging from everyday to every 28th day. This feature is designed to meet the growing needs and restrictions imposed by local governments and to conserve 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 2100.

Start-Time Stacking

The Timer has the intelligence to stack start times that overlap. If you enter two or more start times that overlap (in the same or in different programs), the Timer will not activate two stations at the same time. Instead, the Timer activates the first station and then activates the next station(s) in sequence after the first station finishes its preset watering duration. The Timer will NOT stack to the next calendar day. This prevents the Timer from violating an odd or even day watering schedule.
You can set the watering duration from 1 to 99 minutes. Press and hold the + key to advance the number of minutes, or use the - key to go in reverse, then press ENTER. When the minutes are set, A or B will appear over station 1 and the cursor will advance to station 2 and begin blinking. Simply repeat these steps to set watering durations for all zones on this program To skip a station, press the NEXT key. To erase previously programmed watering durations, press the CLEAR key.
Assigning Watering Days for Program A
Turn the rotary dial to DAY OF WEEK in program A. The display will show an A and the cursor will blink under the days of week Monday, Tuesday, Wednesday, etc. [See Figure 6].

Using Manual Operation

Turn the rotary dial to AUTO.
The manual operation mode allows you to set durations in any of the stations from 1 to 99 minutes. Press the MANUAL key. Then press NEXT three times. The display will show a blinking cursor on station 1 along with - - MINS [See Figure 12].

FIGURE 12: LCD Display with Manual Operation
Manual and Semi-Automatic Modes
The Timer gives you a number of manual and semi-automatic modes for flexibility in watering. You can override the Timers automatic programming in a variety of ways.
FIGURE 6: LCD Display with Watering Days
To set the number of minutes for watering duration, press and Press ENTER to activate watering on Monday. An arrow appears under M and the cursor will advance to Tuesday (T), press ENTER to activate watering on this day. Repeat these steps for all days of the week. To skip a day, press NEXT. 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. Note: If you choose to water every 2nd day, you cannot set specific days of the week for watering

Getting Started

Programming the Timer can be accomplished in just a few basic steps. Before you begin programming, it is important to install the batteries, set the time of day and date, and establish a watering plan.
hold the + key to advance to desired number of watering minutes. Use the - key to go in reverse. Press ENTER to begin watering. To skip a station, press NEXT until the cursor is blinking over the station number you wish to program. Example: To set station 3 for five minutes, press the MANUAL key; then press the NEXT key five times to select the manual operation mode and advance to watering for station 3; using the + or - key, set the manual watering duration to five minutes; then press ENTER [See Figure 13].

Install the Batteries

The Timer requires two AA batteries to maintain the time, date, and programs in case of AC power loss. In a typical installation, fully charged batteries should provide sufficient power for approximately three years of operation. Remove the terminal cover. Insert two AA batteries into the battery compartment. Return the terminal cover to its closed position.
Assigning Watering Intervals for Program B
Program B is used to water at specific intervals between days (1 to 28), or on odd or even calender dates. The Timer has a leap-year compensator and will ensure conformance to the odd and even schedule through the year 2100.
Turn the rotary dial to WATERING INTERVAL. The cursor will blink to the left of the word INTERVAL [See Figure 7].
FIGURE 13: Manual Watering Station 3 for Five Minutes

Page 2

Each valve has two wires. One wire is to be connected as the common. The common wires for all the valves can be connected together to one common wire going to the timer. The other valve wire is to be connected to the specific station wire that will control that valve [See Figure 17]. All wires should be joined together using wire nuts, solder, and/or vinyl tape. For additional protection to waterproof connections, a WaterMaster grease cap can be used. To avoid electrical hazards, only one valve should be connected to each station. The rated output is 24 volts AC at less than 0.240 Amps. Do not use solenoids that exceed these values.

PLAN HEAD PLACEMENT Head to Head Coverage
Proper sprinkler placement allows even watering and reduces dry patches. Proper placement requires: Head to head coverage: Each sprinkler should spray to the head beside and across it. Equal spacing between heads: Permits uniform water distribution.

Placement Example: Good

Good Overlap Head to head coverage

Placement Example: Bad

There is not enough overlap. The center is not getting water. Not enough overlap No coverage in center

Sidewalk

Evenly space strip heads on narrow sections.

Narrow Strips

On narrow strips of grass use strip pattern spray heads and space them evenly apart. These heads may be used for narrow strips up to 4 feet wide.

Place Heads in Corners

Begin by placing a sprinkler in each corner on your drawing. Use a compass to draw the spray pattern.
Note: Use chart 2 on page 20 to obtain spray distance.

Page 8

Add Heads and Adjust Spacing
Add sprinklers along the sides or center to increase coverage.
CREATING WATERING ZONES OR STATIONS
A watering zone or station consists of a group of sprinklers attached to one valve. The number of heads per zone will be determined in this section.

Purpose of Zones

Zones are designed to: Maintain adequate water flow for optimal spray coverage (Avoid dry patches) Separate areas based on watering requirements - Shade vs. Full Sun Areas - Lawn vs. Shrubs
Important: Do not mix sprinkler types in the same zone (e.g. Gear Drive, Impacts, Pop-Ups and Bubblers) Do not exceed the maximum sprinkler heads recommended per zone Use the recommended pipe size in this guide. Smaller diameter pipe will decrease the water flow.
Group Heads of Same Type in the Same Area
Starting with large area heads, use the following example as a guide. Identify all large area heads on your drawing.
Divide Large Area Heads into Zones STEP 1: Maximum Heads Per Zone
Use the following information (collected earlier) to determine zone capacity: Main Line Size Water Pressure (PSI) Large area head selected Use Orbits Quick Reference (Chart 1, Page 20) to determine the maximum heads per zone for your sprinkler system.

Large area heads circled

60 PSI
Example We have determined that our home has a Main Line size of 3/4 with a Static Water Pressure of 60 psi. Based on this information, and using the Quick Reference, we see that we cannot use more than three Voyager II sprinklers in the same zone.
STEP 2: Identifying Sprinklers in a Zone
Begin grouping large area heads, ensure you do not exceed your Maximum Heads per zone number.
Example Since we determined (in our example above) that 3 Voyager II heads is the maximum zone capacity, we grouped all large area heads into 2 zones.
Step 3: Medium and Small Area Head Zones
Repeat steps 1 & 2 to determine and identify zones for Medium Areas Heads. Repeat again for Small Area Heads.

Step 4: Number Each Zone

Assign a number to each zone.

PLAN VALVE PLACEMENT
You'll need to select a location for your main shut-off valve and the best location for the sprinkler valve manifold.

Main Shut-Off Valve

The Main Sprinkler Shut-Off valve is the valve that shuts off water to the entire sprinkler system. Connection to the main water supply is downstream of your water meter. Mark the location on your plan.

FRONT VALVE MANIFOLD

MAIN LINE TO REAR MANIFOLD MAIN LINE
MAIN SPRINKLER SHUT-OFF VALVE

TO HOUSE WATER METER

Valve Manifold Location
One valve will be used for each zone. Valves that are grouped together are called a manifold. Its common to install one manifold in the front yard and one in back.
Mark the Location on Your Plan
Tip: The valve manifold(s) should be installed in an accessible location, away from heavy foot traffic, where it is easy to operate and service. It's also a good idea to locate the manifold on elevated ground, to avoid water accumulating around the valves.

Plan Backflow Prevention

A backflow prevention device is used to stop foreign material from siphoning back into the main water supply. The local code information you gathered from your water district should include the type of device to install and where and how it should be installed. Plan a location for your backflow prevention device and draw it on your layout.

Three common types

Double Check

Pressure Vacuum Breaker

Automatic Anti-Siphon Valve
Note: For certain Canadian areas Dual Check Valves are used

Page 11

DIAGRAM PIPE LAYOUT
You need to plan and draw the layout for your main sprinkler line and lines for each zone.
Draw the Main Sprinkler Line Route Use a direct route to draw the main sprinkler line from the main shut-off valve to the front and back yard manifolds.
Important: Your main sprinkler line should be 1 size larger than the water main supply line.

Main Sprinkler Line

Header and Lateral Lines Guidelines
Header lines Attaches to a valve and supplies water to the lateral lines Do not use pipe smaller than 1" Do not attach sprinklers to this line Lateral lines Pipe that branches off from the header line and supply water to the sprinkler heads Do not use pipe smaller than 3/4"

Good Layout Example

This is a good layout because the water is evenly distributed between the lateral lines and individual sprinklers.

Lateral Header

Bad Layout Example
This is a bad layout because there is no header line. The sprinkler heads, located at the end of the line, will have less water pressure than the heads located closer to the valve.

Page 12

Header Line
Draw a header line from the manifold to each zone. Header lines will be intersected with lateral lines. Sprinkler heads should not be installed on this line.

Use 1" Pipe

Lateral Lines
Draw lateral lines that connect the header line to sprinkler heads. These lines should be branching, not circular.

Use 3/4" pipe

PLAN TIMER LOCATION
Select a location near a power source and where it's easy to access. You'll need to be able to run sprinkler wire to each valve. If you select a location outside, the timer should be made for outdoor mounting or protected with a weather resistant box.

INSTALLATION

This section will show you how to install your sprinkler system.
Marking Head and Pipe Location
Begin by marking the entire layout Use Orbit sprinkler flags to mark each head. Use ground paint to mark where sprinkler pipes will run.

SYSTEM LAYOUT

Painted Lines
Important: Refer to your local code information for any regulations about connecting to the water main. Before digging, contact utility companies and have them mark utility lines. Obtain permits (if required). Always use gloves and safety goggles when installing.

CONNECT TO WATER MAIN

Water Meter and Main Shut-Off

Dig Access Hole

1. Dig to expose the water service line (downstream from the meter). 2. Shut off the main water supply (located next to the meter).
Connect Here for Main Sprinkler Line Water Service Line for House
3. Open a faucet to relieve pressure in the pipes.

Page 14

Connect to Main Line Install a Slip Compression Tee
ShutOff Valve Water Meter
Clean off the water service pipe (downstream from meter). Cut out a section of pipe half the length of the tee.

Slip Joint Tee To House

Water Service Line
Install nuts and washers on each side of the pipe. Insert the slip joint tee and tighten the nuts with a wrench.
Main Sprinkler Line System ShutOff Valve ShutOff Valve Water Meter Pipe Nipple
Shut-Off Valve Non-Freezing Area
Install a Gate or Ball valve after the tee and cover it with an Orbit valve box to protect it and for easy access to the valve. Use fittings to install a Gate or Ball valve on the tee. Turn on water to flush line of debris. Cover with an Orbit valve box.
Slip Joint Tee Water Service Line

Important: Frost Areas or Basement Located Water Meters
Do not use the example above if you are connecting to a water supply line that is located in an area with freezing temperatures or a line that has a water meter located in the basement. For help in making the proper connections go to www.orbitonline.com for detailed recommendations or contact your home improvement center.

BACKFLOW PREVENTION

Install a back-flow prevention device (if required). Use local code information to determine: What type of device is required How it needs to be installed Who is authorized to install it

Page 15

DIG TRENCHES
Using the painted lines as your guide (see System Layout, Page 13) dig trenches to the depth required by local codes.
Important: Refer to your local codes to determine how deep your header and lateral lines need to be. Always contact your local utility companies before digging.
Methods for Digging Trenches
By Hand Ideal for soft soils and very small jobs With Trenching Machine Available at equipment rental dealers
Under Driveways and Sidewalks
Use an Orbit Walkway Tunnel Kit (part # 53333, 91129) to tunnel under obstacles. Dig a trench on both sides. Attach a garden hose to the tunneling pipe.
Expansion Joint Birds eye view Sidewalk
Turn on the garden hose faucet. Work the pipe back and forth, allowing the water spray to form a tunnel.

WORKING WITH PIPE

Working with PVC Pipe
Using an Orbit cutting tool, cut pipe to length and clean the end. Apply PVC primer and PVC cement, using instructions provided. Insert pipe into fitting.
Decide whether you'll use PVC or Polyethylene pipe for your system. Both types are easy to use, but they are assembled differently. Read about each type below to make your selection.
Working with Polyethylene Pipe
Using an Orbit cutting tool, cut poly-pipe to length. Slide a stainless steel clamp over the end of the pipe. Insert a barbed fitting into the pipe. Tighten the clamp over the pipe and fitting.
Warning: Poly pipe should not be used for the main line to the manifold.

Page 16

INSTALL MAIN LINE
Use PVC schedule 40 (or other pressure-rated pipe) to connect the main shut-off valve to the valve manifold(s).
Important: Use pipe one size larger than your supply line. Using pipe smaller than the main supply line will reduce your water flow and will lead to gaps in spray coverage. (For example, use 1" pipe if your supply line is 3/4")

INSTALL MANIFOLD

The easiest way to install a manifold is with an Orbit Pre-Assembled Manifold. Purchase a manifold with one valve for each sprinkler zone. Installs in minutes Works with both Poly-Pipe and PVC Systems Cost effective Expandable for future sprinkler additions
Note: Anti-siphon pre-assembled manifolds are available for areas requiring use of an anti-siphon valve
Pre-Assembled Manifold Connecting the Manifold to the Main Line
1" Male Threaded Fitting
Before connecting the manifold, open the main shut-off valve to flush dirt from the main sprinkler line. Connect the Pre-Assembled Manifold to the main sprinkler line using a 1" threaded fitting.

Page 17

CONNECT ZONES

Install Header Lines

Connect 1" pipe to each valve and run it to the assigned zone.

PVC or Poly Tee

PVC or Poly Cross
Use fittings (elbow, cross or tee) for each lateral line.

Install Lateral Lines

Fittings with Threaded Outlet
Connect 3/4" lateral lines to the header line. Run lateral line to each sprinkler location. Install Tees or Elbow at each sprinkler location.

Lateral Line

Freezing Areas Install Line Drains

1" Male Threa

Replace with Manual Drain Valve

Lateral and Header Lines

Canister Heads: Install an automatic drain valve in the bottom inlet of all canisters. End of Sprinkler Line: Install an automatic drain valve after the last head on the end of each sloped line. Low Spots: Install a tee and automatic drain valve for low spots on sprinkler head lines.

Main Line

Manifold: Remove the end cap and install a ball or gate manual drain valve.

Flush Sprinkler Lines Prior to Installing Heads
Ensure PVC glue has dried adequately. Turn on the main line sprinkler valve. Manually turn on one valve at a time (see valve instruction booklet). Run each valve for a few minutes.
Installing Heads and Testing
Attach sprinkler heads to each riser and adjust the height to proper level. Place enough soil in the trench to stabilize heads but don't fill the trench. Manually turn on one valve at a time. Check for leaks.
Important: Adjust heads for proper spray pattern and check for adequate head to head coverage.

CONNECTING SPRINKLER WIRE

Wiring the Valves

Using wire nuts and grease caps, connect the wires as shown: Connect one wire from each valve to the white (common) sprinkler wire. Connect the 2nd wire from each valve to a separate color wire.
Sprinkler wire consists of one white (common) and 4 or 6 colored strands. The sprinkler wire needs to have at least one more wire strand than the number of valves being installed.
Sprinkler Wire Wire 1 Wire 2 Common Wire Common Wire White
Tip: Orbits Pre-Assembled Manifold with Snap-Wire Connection makes wiring valves easy. Just plug in the valve jack into the water-tight Snap-Wire housing and insert sprinkler wire into the other side. No confusing wiring or messy grease caps (see page 22 for more info).
Run Sprinkler Wires to Timer
Most often you can use an existing sprinkler pipe trench to run your sprinkler wire. In areas of frequent digging, a conduit pipe is used to protect the wire.
Wiring Your Sprinkler Timer

Pump Com1 Com2 24VAC

Unplug your timer from the power source (if hard wired turn off appropriate breaker switch or remove fuse). Connect each colored sprinkler wire to a separate numbered terminal (on the timer). Connect the white (common) wire to the common terminal on the timer. Restore power to your timer. To test proper wiring, manually run each station from the timer.
