HOW THE BACKUP SYSTEM WORKS
The IBOC Plus utilizes non-volatile memory storage to prevent
watering program information from becoming lost in the event of a
power failure. Even the time and date will be retained for the first
10 minutes without power.
A fully charged 6-volt alkaline lantern battery will operate the
controller for more than a year. The SPC-2 (Solar Power Converter)
module will operate the IBOC Plus controller for up to six years,
assuming it receives sunlight for an average of two hours per day.
Once a power source is applied, the controller can be fully
programmed for operation.
Note: If you wish to program the controller prior to installation,
connect the battery at this time. Battery removal will be necessary
prior to installing the controller cabinet. The program memory will be
retained with the battery disconnected.
INSTALLING THE BATTERY
Note: A battery is not provided with the controller. A common 6-volt
alkaline lantern battery (type: NEDA 918A) with screw-type
terminals is required. Use an Energizer type #521, Duracell MN 918 or
equivalent.
Caution: Batteries contain hazardous material. Always handle
and discard batteries properly in accordance with the battery
manufacturer’s recommendations.
1. Remove the phillips screw from the
right edge of the control panel enabling
the panel to swing outward.
2. Install the battery insulator plate (A) and
retainer strap (B) as shown in Figure 3.
3. Install the battery and secure with the
retainer strap.
4. Using the wires provided, connect the
positive (+) battery terminal to the
terminal board terminal labeled “Battery Input.” Connect the
negative (–) battery terminal post to “Battery Gnd.”
Note: The battery condition is displayed as a percentage of capacity
remaining while the controller is idle. The battery should be replaced
when the capacity drops below 40%.

General Information
HOW THE ELECTRONIC CIRCUIT
BREAKER WORKS
The controller is equipped with an electronic circuit breaker. If the
controller detects a short or open circuit, the affected station (valve)
will be turned off automatically. The display will then show
information for the station or stations regarding the problem
condition. The controller continues to automatically water the other
stations. Each automatic start will attempt another cycle and retest
the short-circuited valve.
Listed below are the most common conditions which will activate the
electronic circuit breaker.
Condition: The word “Short” displays with one or more station
numbers.
Diagnosis: One or more stations are shorted.
Solution: Check the wiring of the displayed stations for the cause of
the shorted condition. Repair valve(s) and/or wiring as
needed.
Diagnosis: Overload condition caused by more than one valve
connected to the same station terminal.
Solution: Ensure only one valve is connected to each station
terminal.Three valves may be operated concurrently, but
they must be on separate stations operating on separate
programs.
Condition: The word “Open” displays with one or more station
numbers.
Diagnosis: An open circuit condition exists at one or more valve
solenoids.
Solution: Check wiring of the reported station(s) for loose or
broken connections.
Note: If a master valve is not installed, ensure that master valve
operation is disabled. See Master Valve Operation on page 12 for
details.
After correcting the problem, return the controller to normal
operation as follows:
1. Set the dial to the following
AUTO RUN
positions.
2. Press the
–/
OFF
button to clear the display and return the
controller to the normal operating mode.

HOW THE SENSOR FEATURE WO RKS
The IBOC Plus is equipped to operate with an optional rain sensing
device, commonly called a “Rain Switch,” to prevent automatic
watering during rain.
The rain switch is a simple device, typically installed on a roof
overhang or stationary structure exposed to rainfall and full sun, and
shielded from irrigation spray. The rain switch wiring is connected to
the sensor terminals provided on the controller terminal board.
Rain sensor operation is selectable by program, enabling sensor control
to be allocated to specific watering programs as needed.
When rain occurs, the switch senses the moisture and causes the
controller to terminate all output to the field. The electronic
programming portion of the controller is isolated from the rain sensor
switch, and continues to operate as programmed. When rain stops and
the rain switch returns to its normal state, field output is restored,
enabling watering to resume as scheduled.

GETTING STARTED
WHAT IS A WATERING PROGRAM?
In basic terms, a watering program is a small set of instructions which tells
the controller when to start a watering cycle, which stations will operate
during the cycle, which days the cycle will be active and how long each
station will operate during the cycle. The IBOC Plus has three independent
watering programs for your use. Separate programs are usually used to group
stations with similar watering requirements. For example, you might use one
program to water lawns in full sun every day. Another program could be
used to water lawns in partial shade only on Monday, Wednesday and
Friday. Trees and shrubs using drip irrigation could run on a separate
program once every two weeks. The garden area requirements might include
watering every other day. As you can see, the availability of three programs
allows you to have unique watering programs for your varied landscape
needs.
Programming the Controller
PROGRAMMING THE
CONTROLLER
WHAT IS A PROGRAM WATERING CYCLE?
When a watering start time is selected, that time becomes the beginning
of an automatic watering cycle. A watering cycle operates each station
assigned to the program, one by one, in numerical order.
In the following example, (also shown on the sample watering plan on
page 10) we have set up Program A to start at 2:00 a.m. and again at
3:00 a.m. on a 1-day interval (every day). Stations 1, 2, 4 and 5 are front
and back yard lawn areas which get full sun throughout the day. These
stations will run for 10 minutes each for a total of 20 minutes run time
per day. Stations 3, 6 and 7 are lawn areas which are shaded during the
afternoon hours. These areas require less water, so we have assigned them
to Program B and set them to run for 20 minutes on a 2-day interval
(every other day).
At 2:00 a.m., Program A watering cycle starts. Station 1 turns on, runs
for 10 minutes, and shuts off. Station 2 turns on, runs for 10 minutes, and
turns off. Stations 4 and 5 operate sequentially in the same manner, each
running for their set run time. When Station 5 shuts off, the watering
cycle is completed for the first start time. At 3:00 a.m., the watering
cycle starts again and repeats the same station-by-station watering
sequence.
Note that we have 40 minutes total watering time per cycle in
Program A. If we had set the next start time at 2:30 a.m., the start time
would have been delayed until 2:40 a.m., enabling the first cycle to finish
as programmed. This function is called “start time stacking”, and can
occur within each program.
Watering programs, however, operate independently, which means that
two or more programs can run simultaneously. In our example,
Program B will also start at 2:00 a.m. Therefore, Stations 1 and 3 will
turn on at the same time, and Station 2 will turn on while Station 3 is
running. This feature enables more watering to be completed within the
prime “watering window”, which is generally between Midnight and
6:00 a.m.
Note: When scheduling watering programs to run simultaneously, it is
important to ensure the water supply has sufficient pressure and volume
to maintain optimum sprinkler performance.

SELECTING THE DAYS TO WATER
Several watering day scheduling options are available. Each watering
program can utilize any ONE of the following schedules:
• Days of the week
Use this type of schedule to water on specific days of the week. The
days are displayed as three-letter abbreviations. For example, Sunday is
Sun, Monday is Mon, etc. Only the days you select to water will
remain on the display.
• Odd or Even Days
To select every o dd or even number calendar day, use this option.
Because the 31st and the 1st are both odd number days, the 31st is
automatically removed from the schedule. This watering day option
also enables selected days of the week to be removed from the
schedule.
• Skip Days
Selecting watering days by Skip Days enables a specific number of days
between watering to be selected. For example, selecting Skip 1-day
schedules watering for every day. Skip 2-days schedules watering for
every other day. Skip day scheduling is selectable from 1 to 62 days.
Another setting within the Skip Days schedule is the Day # or current
day of the schedule. The Day # can be set for any day within the Skip
Days schedule. When the Day # equals the Skip Days number, a
watering day occurs. The Day number automatically increases by one
every day. For example, to water today then every third day, a Skip 3
would be set with D
AY # 3. Or, to water every 5 days starting
tomorrow, a Skip 5 would be selected with D
AY # 4.

This section includes instructions for mounting the controller cabinet
and making the necessary wiring connections. To ensure safe
operation, it is important to follow the instructions carefully.
SELECTING AN INSTALLATION SITE
Selecting the proper installation site for the controller is essential to
safe and reliable operation. The IBOC Plus features a weather-resistant
cabinet enabling outdoor installation.
The controller should be installed on a vertical wall or other sturdy
structure with the display at approximately eye level. An optional
pedestal mount, model # P2B is available for stand-alone installation.
It is important to select a location that shades the controller during
the hottest hours of the day and provides as much protection from
rain, wind and snow as possible. Never install the controller where it
will be exposed to direct spray from the sprinklers.
Note: When mounting the IBOC Plus controller with a SPC-2 Solar
Power Convertor, it is important to select a location that provides
maximum protection from rain, snow and direct irrigation spray while
providing the SPC-2 exposure to sunlight for a minimum of two hours
per day.
Installation procedures
INSTALLATION PROCEDURES
17
MOUNTING THE CONTROLLER
1. Position the mounting template (provided) on the wall at
approximately eye level. Using a small punch or nail, mark the
locations of the top and bottom centerline mounting holes and
the additional lower holes if extra cabinet support is desired.
2. Drill pilot holes at least 1-1/4" (32mm) deep using a 3/32"
(2.5mm) drill for wall stud application, or 1/4" (6.5mm) drill for
masonry.
3. For the masonry wall installation only, insert the plastic screw
anchors (provided) into the pilot holes.
4. Place a small plastic washer and a rubber washer (provided) on each
screw. Install the #10 screws into the top and bottom locations
leaving the screw head about 1/2" (13mm) from the wall.
Note: If installing additional lower mounting screws, remove
plastic hole plugs at this time.
5. Unlock and open the cabinet cover. Remove the cover by sliding
it toward the top of the cabinet.
6. Remove the phillips screw from the right edge of the control panel
enabling the panel to swing outward.
7. To remove the control panel from the cabinet, first disconnect the
ribbon cable from the terminal board. With the panel in the fully
opened position, slide it toward the top of the cabinet.
8. Hang the cabinet on the screws using the keyhole slots. Ensure the
screws engage the slotted portion of the keyhole with the plastic
washer positioned between the screw head and the inner cabinet
wall. Tighten the screws securely. Install additional screws in the
lower left and/or right mounting holes as required.
9. Reinstall the control panel and cover.
CONVERTING THE SOLENOIDS
The IBOC Plus controller activates valves by means of an electric
pulse, which latches and releases the solenoid position rather than
providing continuous power to the solenoids. This requires a DC
latching solenoid for each irrigation control valve.
The DC latching solenoid is designed as a direct replacement for the
standard 24 V a.c. solenoid (which will not work with the IBOC Plus
controller). No additional adapting is required for solenoid installation.
Installation Procedures
18
Note: When connecting the DC latching solenoid to the controller,
unlike an AC solenoid which has no specific wiring polarity, the DC
latching solenoid has a power and a common wire. To enable valve
operation, the black wire must be
connected to the valve common and
the red wire to a valve output
terminal. Ensure the solenoid is
assembled with the red and black
wires oriented as shown in Figure 4.
CONNECTING THE
FIELD WIRING
Note: Refer to the recommended
wire size information on page 25.
1. To provide a field common wire, splice one wire to the black wire of
each valve solenoid and optional master valve.
2. Attach a separate control wire to each red valve solenoid wire. Label
the control wires with the intended station number for identification
at the controller.
Caution: All wiring splices must be waterproofed to prevent
short circuits and corrosion.
3. Route all field wires into the controller cabinet through the
2" (52mm) access opening. Remove approximately 1/2" (13mm)
insulation from the ends of each wire.
4. Attach the field common wire to one of the three valve common
terminals labeled “Valve Com.” See Figure 5.
5. Connect each valve control wire to a separate station number
terminal (1-12) and tighten securely. See Figure 5.
6. Connect the Master Valve wire to the terminal labeled MV/Pump.
CONNECTING A RAIN SWITCH SENSOR
The IBOC Plus is designed for use with a normally closed rain sensor
or “Rain Switch.”
Connect a rain switch sensor as follows:
1. Route the two wires from the sensor into the cabinet through the
field wire access opening.
2. Connect the wires to the terminals labeled “Rain Sensor.” See
Figure 5.

Installation Procedures
Note: Although the battery and the SPC-2 share the same input
terminals, only one power source can be connected to the IBOC
Plus at any given time. If using the SPC-2, connect the Orange
6-Volt (+) wire and Black negative (–) wire to the IBOC’s battery
input terminals.
3. By default, sensor operation is disabled for all automatic watering
programs. To enable operation of the sensor, refer to the “Rain
Sensor Operation” on page 7.
Note: Do not connect the rain switch directly to the valve
common wire. Refer to the installation instructions provided with
the rain sensor for additional information.
CONNECTING AN EARTH GROUND
A power surge is a sudden rise in voltage on the power main line. It is
then often followed by a drop in voltage as the power line equipment
tries to protect area users. A lightning strike on the power grid is the
most common cause of power surges and can be damaging to the
controller. Surge protection is built into the IBOC Plus terminal board
to help protect the controller from surge damage by shunting the
voltage to earth ground.

Therefore, an important step in the installation process is to properly
connect the controller to an earth ground source, especially if the
controller is located in a lightning-prone area.
Caution: The built-in surge protection components cannot
effectively protect the controller circuitry from power surge
unless properly connected to an earth ground source.
To connect an earth ground:
1. Route a #12 (2mm
2
) solid copper wire in the shortest and most
direct path from the “Earth Gnd” lug, located on the terminal
board, to an earth ground source such as metal water pipe or
copper-clad ground rod.
2. Clamp the end of the ground wire securely to the pipe or ground
rod. Make sure the wire contact area is free of dirt and corrosion.
This section includes instructions for the following controller
operations:
• Testing Station Operation
• Water Budget
• Off and Rain Delay Modes
• Manual Operations
TESTING STATION OPERATION
This feature enables you to quickly check system operation by
running each station for a selectable test duration from 1 to 10
minutes. Once started, each station will run in numerical order for
the selected test run time.
To perform the station test operation, use the following procedure:
1. Turn the function dial to the
STATION TEST
position. The display
will prompt you to set a watering run time.
2. Use the +/
ON
and/or –/
OFF
button(s) to set the station water
time from 1–10 minutes.
3. Press the
NEXT
button, “Station 1 –Off–” will be displayed.

4. Press the +/ONbutton to begin operation. Allow station 1 to
continue operating for the set run time or change the run time by
using the +/
ON
or –/
OFF
button(s). (Decreasing the run time to less
than one minute will turn off the station.) Each station will run
automatically in numerical sequence or may be manually advanced
to another station by pressing the
NEXT
button until that station is
displayed. Each time the station is advanced (either automatically or
manually) the previous operating station will turn off, enabling only
one station to run at a time.
Note: To stop the test operation at any time, simply turn the
function dial to the
OFF/RAIN DELAY
position and press the –/
OFF
button.
5. When finished, return the function dial to the
AUTO RUN
position.
WATER BUDGETING
The Water Budgeting feature enables you to easily increase or decrease
the station run time (by percentage) of all
stations assigned to a
selected program. This is handy for making temporary overall station
run time adjustments without changing the original run time settings.
Water Budgeting % values range from 10% to 200% in 10%
increments, with 100% being the normal setting.
For example, as the fall season approaches and the temperature
decreases, you may want to reduce the water time for the stations in
program A by 30%. Later you can return station times to their original
values by setting the Water Budgeting % value back to 100%.
Note: It is possible to inadvertently cause start time stacking when
increasing station run time. Careful use of Water Budgeting % will
help prevent this from occurring.
To change the Water Budgeting % values:
1. Turn the function dial to the
WATER BUDGETING (%)
position.
2. Select Program
A, BorC
with the
Program
button.
3. Use the +/
ON
and/or –/
OFF
button(s) to increase or decrease the
percentage value (10–200%).
4. Repeat steps 2 and 3 for other programs as required.
5. Turn the function dial to the
AUTO RUN
position.

Use these function modes to immediately stop all current watering
activity, suspend watering indefinitely or delay automatic watering
programs for a selected number of days (Rain Delay mode).
Turning Off Current Watering Activity
When the function dial is turned to the the
OFF / RAIN DELAY
position
while any station is active, the “Press –/Off to stop all watering”
prompt to be shown. Pressing the –/
OFF
button immediately shuts off
all active stations and suspends all watering activity until the
function dial is turned to another position.
Using the Rain Delay Mode
When the function dial is turned to the
OFF / RAIN DELAY
position while
the controller is inactive, the display prompt “Rain Off Press +/– for
OFF days” will be shown. A number from 1–30 days is entered and the
controller will delay all automatic watering programs until the delay
period lapses. Once the controller is placed in the Rain Delay mode, the
function dial can be turned to other positions for programming,
reviewing and manual operations. The display will show the number of
days remaining in the delay period. The number will automatically
decrease by one digit each day. Automatic operation will resume when
the display shows no delay days remaining.
To select the Rain Delay mo de:
1. Turn the function dial to the
OFF / RAIN DELAY
position.
2. Use the +/
