Ground Wire
The I-Core features a ground lug, which is isolated from the primary AC power, and is used to ground incoming surges from the
communications and output valve wires.
Do NOT connect the primary AC 120/230V electrical ground wire to the
earth ground lug.
1. Use #10 (6 mm) or #8 (10 mm) bare wire to connect the controller
to the ground rod. Route the earth ground wire into the wiring
compartment through the 1 ½" conduit opening at the bottom of the
cabinet. Do not route the ground wire through the same conduit as
the incoming primary AC power.
2. Loosen the ground lug screw; insert the ground wire into the ground
lug and tighten the screw to secure the ground wire. Do not over
tighten.
Acceptable grounding consists of an 8' (2.5 m) copper-clad rod or stake, or
a 4" x 96" (100 mm x 240 cm) copper plate, or both, placed in the earth at
least 8' (2.5m) away from the controller, and with the ground wire at right
angles to the communications and valve wires, if possible. Ideal grounding
resistance would be 10 Ohms or less as measured with a “megger”
or similar device. Please consult the ASIC reference for more detailed
information on proper grounding techniques.

CONNECTING THE POWER AND STATION MODULES
The I-Core controller is supplied with one factory installed power module
and one station module for six stations. Additional station modules may be
added in six station increments to expand the controller’s station capability.
The plastic cabinet I-Core can be expanded to a size of 30 stations, and the
metal cabinet and plastic pedestal I-Core can expand to 42 stations.
STATION MODULE
Station Module Installation
1. Open the inner facepack door and locate the Slide Lock. Move the
Slide Lock bar to the POWER OFF position.
2. The module needs to be inserted into the rst open module slot
position from the left or next available position in the back of the
controller. Do not skip slots by leaving them empty.
3. Insert the module with the gold tab on the top of the module facing
up. Slide the module straight in until it clicks into place.
4. Slide the Slide Lock into the POWER ON position.
5. The controller will automatically identify any new modules that have
been added. You can turn the dial to SET STATION RUN TIMES to
conrm the correct number of stations have been acknowledged.

CONNECTING VALVE WIRES
Connecting Station Valve Wires
Each station module that has been inserted has a grouping of six station
screw terminals corresponding to that particular expansion slot. Once a
station module is installed in a module slot, the station screw terminals
assigned to that module, which are located directly below the station
module, become active.
Each station output is rated for 0.56A max, or enough to operate two
Hunter AC solenoids simultaneously.
1. Route valve wires between control valve location and the controller.
2. At the valves, attach a common wire to either solenoid wire of all the
valves. This is most commonly a white colored wire. Attach a separate
control wire to the remaining wire of each valve. All valve wire splice
connections should be done using waterproof connectors.
3. Open the faceplate at the controller to expose the numbered station
terminals.
4. Route valve wires through the conduit and attach the conduit to the
controller at the 1 ½" (37.5 mm) opening at the bottom of the cabinet.
5. Strip ½" (13 mm) of insulation from the ends of all the wires. Secure
the valve common wire to one of three C (Common) terminals located
of the Power and Accessory terminals. All three common terminals are
active, so the valve common wire may be connected to either one.
Attach all the individual valve control wires to the appropriate station
terminals.

Connecting a Master Valve or Pump Start Relay
Complete this section only if you have a Master Valve or Pump Start Relay
installed. The I-Core controller works with a normally closed master valve
that is typically installed at the supply point of the main line that opens only
when the automatic system is activated. A pump start relay is an electrical
device that uses the irrigation controller to activate a pump to provide
water to your system.
The Master Valve or Pump Start Relay connection is located on the
bottom row of the Power and Accessory Terminals, and is labeled P/MV.
This terminal will supply 24 VAC, 0.32A max, for a single Master Valve
solenoid. For a Pump Start Relay, the relay holding current draw must
not exceed 0.28 amps. If using a Pump Start Relay, it is recommended
that the controller be mounted at least 15' (4.5 m) away from both the
pump start relay and the pump. When a pump is to be operated by
the controller, a pump start relay must be used. Do not connect the
controller directly to the pump — damage to controller will result.
1. Route valve wires between Master Valve or Pump Start Relay location
and the controller.
2. At the Master Valve, attach a common wire to either solenoid wire of
the valve. Attach a separate control wire to the remaining solenoid
wire. At the Pump Start Relay, attach either wire to one of the yellow
wires coming from the Pump Start Relay. Attach the remaining wire to
the other yellow wire at the Relay. All wire splice connections should
be done using waterproof connectors.
3. Open the inner facepack door at the controller.
4. Route the valve wires into the controller via the eld
wire conduit.
5. Connect either wire from the Master Valve or Pump start Relay to the
P/MV terminal located on the bottom row of the Power and Accessory
terminals. Connect the remaining wire to the C (Common) terminal
that is located directly to the left of the P/MV terminal.
The Master Valve or Pump Start Relay can be activated according to a
particular station. The conguration of assigning the Master Valve or Pump
Start Relay according to a particular station will be covered in the Set Pump
Operation (pg. 18).

CONNECTING A WEATHER SENSOR (OPTIONAL AND NOT INCLUDED)
The I-Core controller has the ability of connecting two Hunter Sensors
(three with I-Core Metal) including:
• Mini-Clik®
• Rain Clik™
(including Wireless Rain Clik, Wireless Rain Freeze-Clik)
• Freeze-Clik®
• Wind-Clik®
• Mini-Weather Station (MWS)
• Solar Sync and Wireless Solar Sync ET Sensor
With the I-Core controller, Clik sensors can be programmed to shut down
individual stations, not necessarily the entire controller. Each sensor can be
given its own response instructions according to each station. Hunter Clik
sensors are usually normally closed, and open on alarm. This signals the
controller to suspend watering when precipitation, freeze or wind events
occur. The sensor connects directly to the sensor terminals, which also
allows you to override the sensor by using the Rain Sensor bypass switch
on the face of the controller.
1. To connect Clik sensors, locate the 2 pairs of sensor terminals in the
Power and Accessory Terminal section, labeled S1, S1 and S2, S2 (S3
available on I-Core Metal).
2. Route the wires from the Clik sensor through any of the available
knockouts into the controller cabinet.
3. The sensor connections are made in dedicated pairs. Remove the
sensor jumper wire from one pair of S1 or S2 terminals. Attach one
sensor wire to each of the two S1
or S2 terminals.
4. To connect the Wireless Rain Clik or Wireless Rain Freeze Clik, the
blue and white wires will be connected to the corresponding sensor
terminal as stated above: One into the rst S1 terminal and the other
into the second S1 terminal. Connect one of the yellow wires to the
AC1 terminal and the other yellow wire to the AC2 terminal.
Bypassing the Sensor(s)
If the rain sensor is ACTIVE and automatic or manual operation is required,
simply move the Bypass switch to Bypass.
If the rain sensor switch is left in the ACTIVE position but no sensor is
connected and the jumper wire has been removed, the display on the
I-Core will indicate that the sensor is ACTIVE. This will also be indicated
in the System Status dashboard to the left of the display. The sensor light
will be illuminated RED for ACTIVE, thus having an open circuit. As long as
the sensor is in the ACTIVE mode, any station that has been programmed
to the ACTIVE sensor will not be allowed to water, and will be put into
Suspend mode. If you do not have a sensor and want to eliminate this
possible problem, simply keep the rain sensor switch in the bypass mode,
or install the jumper wire between the sensor terminals if it has been
removed.
Programming of the sensors will be discussed in the Set Sensor Operation
section of Programming and Operation (pg. 18).
Sensor Bypass Switch
This switch will either enable or disable a Rain or Freeze sensor that has
been connected to the controller. When the switch is in the Active position,
the controller will adhere to the state of the sensor and shut down irrigation
if the sensor is in an open state. If the sensor is in a closed state, the
controller will operate as normal. If the sensor is in an open state, but you
would like your automatic irrigation to operate as normal, simply move the
switch to the Bypass position. The sensor will now be overridden and the
controller will operate as programmed.
Once the Sensor Bypass Switch is in the Active position the System Status
Dashboard will acknowledge the switch is in the Active position, and the
Sensor Status light will light up. If the sensor is in an open state, the System
Status Sensor light will be Red. If the sensor is in a closed state, the System
Status Sensor light will be Green.
If you do not have a sensor installed, the position of the Rain Sensor switch
can be in either the Active or the Bypass mode. This is true as long as
the jumper wire connecting the two sensor terminals remain in place. If a
jumper wire has been removed, it will be necessary to keep the Rain Sensor
switch in the Bypass mode, otherwise no automatic irrigation will occur.

except in step 1, you will be connecting the green and black wires from
the Wireless Solar Sync Receiver to the S1 terminal positions. The Wireless
Solar Sync Receiver then communicates with the Wireless Sensor.
The Solar Sync can be programmed to adjust station run times by program.
To set the I-Core to Solar Sync Adjust mode:
1. Turn the dial to Set Seasonal Adjustment. Use the PRG Button to
select the desired program.
2. Press the +/–button to select By Solar Sync Seasonal Adjust mode.
Repeat for other programs if needed (See Sensor Conguration on
page 22).
Once a Solar Sync is connected and programmed the station run times
will be adjusted according to the ndings of the Solar Sync. The Solar
Sync will automatically adjust station run times and can be programmed
independently for each of the four I-Core programs. The Rain Clik and
Freeze-Clik sensor incorporated in the Solar Sync can be programmed by
station which is discussed in the Set Sensor Operation section.
CONNECTING A HUNTER SOLAR SYNC
The Solar Sync is a “smart“ control system that, when connected to the
I-Core, will automatically adjust your controller’s station run times based
upon changes in local climate conditions. The Solar Sync incorporates a
solar and temperature sensor to determine evapotranspiration, also known
as ET. It also utilizes a Rain Clik and Freeze-Clik to shut down your irrigation
when conditions arise.
The I-Core now has the Solar Sync software built into the controller. New
I-Core controllers with built in Solar Sync are easily identied by the new
SOLAR SYNC SETTINGS dial position on the facepack. Because the new
I-Core has built in Solar Sync software, the Solar Sync Sensor is the only
item to be connected to the controller. The Solar Sync module will not be
used and is not compatible with I-Core controllers that have Solar Sync
software built in.
1. To connect the Solar Sync Sensor route the black and green sensor
wires into the controller and connect them to the two S1 terminal
positions. It does not matter which wire goes to which S1 terminal, but
the S1 terminal must be used when connecting a Solar Sync sensor.
2. Mount the Solar Sync sensor in a location that receives as much
sunlight as possible for best results. (see Solar Sync owner’s manual for
more details on sensor location)
3. The Solar Sync Sensor must now be assigned to the SEN1 location
in the controller. Turn the dial to the ADVANCED FEATURES position.
4. Use the ▼button to scroll to Sensor Conguration and press the +
button.
5. In the SEN1 position use the +button to scroll through the options
until Solar Sync is shown. The I-Core now recognizes that a Solar Sync
sensor has been connected.

CONNECTING A FLOW SENSOR (OPTIONAL)
The I-Core is designed to operate primarily with the Hunter HFS Flow
Sensors. However, some non-Hunter ow sensors can be used.
1. To connect a Hunter HFS Flow Sensor, route the pair of 18 AWG
(1 mm) wires from the sensor into the cabinet (max distance of
1,000 ft.).
2. Locate a pair of S1 or S2 (S3 available on I-Core Metal) sensor red and
black terminals on the Power and Accessories Terminals. Remove the
jumper wire from one pair or S1 or S2 terminals. You may use either
pair of S1 or S2 sensor terminals for a ow sensor. Connect the red
wire from the HFS to the red terminal, and the black wire from the HFS
to the black terminal.
3. I-Core allows you to connect two ow sensors at one time. In that
case, one of the ow sensors would connect to the red S1 terminal
and the black S1 terminal, while the second ow sensor would
connect to the red S2 terminal and the black S2 terminal.
NOTE: I-Core has only one Pump/Master Valve output.
If 2 ow sensors are used on 2 different points of
connection, only one of them will have a master valve
available for alarm shutdowns unless the single PMV is
congured to operate 2 master valves simultaneously.
Flow setup, learning, and conguration will be described later in the manual
under Advanced Features (pg. 22). A complete step by step Flow Monitoring
procedure is also available in the Hidden Features section (pg. 29).
NOTE: If a ow sensor is going to be connected to the
controller and ow will be monitored, there is critical
information that needs to be read in the Controller
Diagnostics and Troubleshooting section under System
Status Dashboard Flow. It is very important to
understand how the controller will monitor ow under
certain circumstances and what diagnostic testing will
be performed in alarm situations.

CONNECTING A REMOTE CONTROL (OPTIONAL)
The I-Core controller has factory installed SmartPort®. This provides a
remote ready connection for Hunter ICR, ROAM, and SRR remotes.
To connect a remote, remove the weather resistant rubber cover on the
SmartPort, align the remote receiver’s pins with the connector, and push
rmly until the receiver is fully seated. Refer to the remote control owner's
manual for further information on how to operate your Hunter remote.
The I-Core can overlap remote commands allowing up to ve valves to
run simultaneously. Therefore, if a station is being operated and a remote
command is sent to activate another station, that station will not turn off
the existing station, but run both stations simultaneously.
If ve valves are running and a new remote command is received to start
another event, the command will be ignored. No new remote commands
will be accepted until one of the ve events completes watering. I-Core
can run automatic programs and manual stations simultaneously. Each
command will be displayed on the screen, indicating the event is watering,
in the order the event took place.
Remote commands will also be allowed if the controller is in the OFF
position. With the dial in the OFF position, the controller will respond to
single station or program manual commands. In the OFF position, the
display will not indicate that a station is watering; you will only see the
System Status Dashboard Light turn green next to Station, indicating that
there is a station running. When the controller receives a Manual Program
remote command, the controller will only activate the stations within the
Program. If a station within the Program is programmed to a sensor that is
Active, that particular station will not operate and will be put into suspend
mode. The controller will count down that station’s programmed run time
without actually running the station.
If there are stations within the program that follow this station numerically
and are NOT programmed to the sensor, these stations will run and the
controller will observe the remote command and follow through the rest of
the program. The programming of stations to a sensor will be discussed in
the Set Sensor Operation section of the manual (pg. 18).

QUICK START
The I-Core controller offers maximum scheduling exibility including
four programs, each with up to eight daily start times, permitting plants
with different watering requirements to be separated on different day
schedules. Multiple start times permit morning, afternoon, and evening
watering, perfect for the establishment of new lawns and thirsty annual
owers. A built in 365-day calendar clock accommodates odd/even
watering restrictions without requiring monthly reprogramming. You may
simply designate days of the week you want to water for ease or use the
convenient interval day watering. All of this and more will be explained in
detail throughout the programming and operation section. You will begin
to notice just how easy the I-Core programming can be and the capabilities
of advanced features the I-Core offers to set this controller apart from its
competition.
The following are basic programming instructions to initially program
your I-Core controller. If more complex programming is required, please
reference the I-Core Programming following this page.
1. Set Current Date/Time: Use the ◄ and ►buttons to navigate, and
the + / – buttons to change the ashing selection to the correct Date
and Time.
2. Set Program Start Times: Each automatic program has 8 start
times available. Use the ◄and ►buttons to navigate through the
different start times, and the + / – buttons to change the time. The
time changes in 15 minute increments, and by holding down the
+ / – buttons the time will scroll faster. Use the PRG button to select
individual programs.
NOTE: The number shown on the screen does not
indicate a station number, but indicates an individual
start time for that particular Program.
3. Set Station Run Times: This dial position allows you to assign a
station’s run time with a particular program. If you need to change
the program, you are assigning a station run time, simply press the
PRG button. Use ◄ and ►buttons to navigate through the station
numbers, and the + / – buttons to change the length of run time in
hours: minutes.
4. Set Days to Water: Use the PRG button to select the Program. Use
the ▲or ▼buttons to move the ►cursor next to a day, and then use
the + / – buttons to indicate a water day or a non water day. When
using Days of the Week scheduling, a will indicate a water day, and
a _will indicate a No-Water Day. The ◄ and ►arrow buttons will
change the schedule type, including Days of the Week, Odd/Even
Days, and Interval Watering.
NOTE: For Days of the Week scheduling, a check mark
indicates a water day, and no check mark indicates a
non water day. When programming Odd/Even and
Interval watering schedules, the X that appears next to
the day will indicate a non water day for that schedule,
and all other days with no X will be available water days
depending on the schedule programmed.
5. Set Pump Operation (optional): The Pump/Master Valve output may
be set by station. If a Pump/Master Valve is in use you need to make
sure the stations are set to On. If no Pump/Master Valve is in use, this
is not required. The ◄ and ►buttons scroll through the stations and
the + / – buttons set the stations to On or Off.
6. Return the Dial to the Run Position: This is all that is required for
the most basic operations. The I-Core will water automatically in any
dial position except OFF, with the previous steps discussed being
programmed.
7. Test Program: The test program will start every station in the
controller sequentially, in numerical order, for the specied time. Turn
the dial to the RUN position. Hold down the PRG button for three
seconds. The screen will change automatically and display station
number 1 and a ashing run time of 0:00. Enter the desired run time in
hours: minutes by using the + / – buttons. Within ve seconds the test
program will begin. Test program will operate stations in sequential
order.
8. Manual Start: With the dial in the RUN position, there is a shortcut
to manually start a program. Press and hold the ►button. The screen
will change and indicate station 1 and the programmed run time
for Program A. If you would like to change the Program you want
to manually run, release the ►button and press the PRG button to
change the Program selection. The manual program will start in a few
seconds.
POWER FAILURES
Due to the possibility of power failures, the I-Core has nonvolatile memory
to preserve programming data indenitely. The 9-volt battery is required
for programming of the controller in the absense of AC power. Both the
9-volt battery and lithium battery (if a 9-volt battery is not installed), will
maintain the current time and day during power outages. If the power goes
out, the display will acknowledge there is No A/C Power. No stations will
water if the display reads No A/C Power, until AC power is restored to the
controller.
14

Setting Current Date and Time
The SET CURRENT DATE AND TIME dial position allows you to set the
current date and time in your I-Core controller.
1. Turn the dial to the SET CURRENT DATE/TIME position.
2. The year will be ashing in the display. Use the + / – button to change
the year. Press the ►button to proceed.
3. The month will be ashing. Use the + / – button to change the month.
Press the ► button to proceed.
4. The day will be ashing. Use the + / – button to change the day. Press
the ► button to proceed and set the time.
5. Use the + / – button to select AM, PM, or 24 HR. Press the ► button.
6. Use the + / – button to set the hour. Press the ► to set the minutes.
Use the + / – button to change the minutes until they are correct. The
correct date and time have now been set. Always return the dial to the
RUN position when you are nished programming the controller.
Setting Program Start Times
The SET PROGRAM START TIMES mode allows you to program start times
for each of the four programs (A, B, C, or D) independently. Up to eight
start times per day can be set for each program.
NOTE: Two programs are allowed to run at the same
time if there Start Times coincide or overlap. This is an
important element to consider when programming the
Start Times if the hydraulics of your system do not allow
for more than one station to run at the same time.
1. Turn the dial to the SET PROGRAM START TIMES position.
2. Program A and start time 1 will be displayed. If necessary, you can
select Program B, C, or D by pressing the PRG button.
3. The program start time will be ashing. Use the + / – button to
change the start time. The time will change in 15 minute increments.
Press the ►button to select an additional start time if you would
like more than one watering cycle per day to occur for that program.
Programs A, B, C have eight start times per day, while program D has
16 start times. Press the PRG button to change between programs A,
B, C, and D to assign a start time to the particular program.
4. To eliminate a program start time turn the dial to the SET PROGRAM
START TIMES position, use the PRG button to select the program and
the ►button to select the start time you would like to eliminate. Press
the + / – button until you reach 12:00 AM. Press the –button once more
and the display will show dashed lines --:--, indicating no start time.
If a program start time is skipped (for example, a start time is set for 1 and
3), the start time will be accepted, but when returning to this dial position,
the start times will be moved to sequential order (the Start Time 3 will be
moved to 2).
If an earlier start time is set for a higher-numbered start (for example,
start time 1 is set to 4:00 AM, and start time 2 is set to 3:00 AM), when
returning to this dial position the start times will have been reorganized in
chronological order. The lowest numbered start time will always have the
earliest time of day (in the example, the start time 1 will be at 3:00 AM and
start time 2 at 4:00 AM).
NOTE: One start time will activate all stations
sequentially that are assigned to a program. Multiple
start times are typically used when separate morning,
afternoon, or evening watering cycles are required. You
cannot enter a start time for each station. If you only
want to water your stations once a day within a particular
program, you would only program start time 1. The rest
of the start times 2 through 8 would be left blank --:--.
The I-Core controller has the ability to operate ve Hunter valves at one
time, and, therefore, allows for more than one program to run at the same
time. Only two programs can be allowed to run concurrently. If you set two
programs to have the same start time, or their start times overlap, both
programs will run concurrently. This is a great feature if you have a short
water window and the available water to feed multiple stations; however, it
could become an issue if the ow of your irrigation system cannot support
operating multiple stations at the same time.
If you do not have the available water to operate multiple stations at one
time, you will need to consider and calculate when each program will nish,
or review the Total Watering Time for each program within the ADVANCED
FEATURES dial position. Each Program’s Start Time must be programmed
to start after the previous Program nishes in order to eliminate the
possibility of multiple Programs watering at once.
Setting Station Run Times
(Length of Watering for Each Station)
The SET STATION RUN TIMES mode allows you to enter a length of run
time for each station assigned to a particular program. Each station that
has a run time associated with a program will be activated and operate one
after another sequentially with each start time for that program.
1. Turn the dial to the SET STATION RUN TIMES position.
2. The display will show the station number and program. Use the PRG
button to select a program.
3. Use the + / – button to change the station run time on the display.
4. Use the ►button to advance to the next station for which you would
like to enter a run time.
5. When nished entering run times, rotate the dial to the RUN position.
By pressing the PRG button, you can move between programs while
staying on the same station. However, it is recommended that one program
is completed before going on to the next program.
CONTROLLER PROGRAMMING

NOTE: When entering run times the Seasonal Adjusted
run time will be displayed in the lower right corner of
the display. The default Seasonal Adjustment setting is
100%. If the ACTUAL value is different from the
PROGRAMMED value, the Seasonal Adjustment has
been changed from the default of 100% to a new value.
The ACTUAL run time is the duration the station will water based upon the
seasonal adjustment value. Detailed information on Seasonal Adjustment
can be found in the Set Seasonal Adjustment section (pg. 17).
Setting Days to Water
SET DAYS TO WATER mode allows you to select days you would like to
water for each program independently.
1. Turn the dial to SET DAYS TO WATER position.
2. Program A water days will be displayed. Use the PRG button to select
your desired program (A, B, C, or D).
3. Use the ◄ and ►button to change from 1) Specic Days of the Week;
2) Odd Day Watering; 3) Even Day Watering; or 4) Interval Day
Watering. Each program can only be assigned one type of water day
option at a time.
Selecting Specic Days of the Week to Water
1. Turn the dial to SET DAYS TO WATER position.
2. Use the PRG button to select your desired program (A, B, C, or D).
3. Use the ◄ and ►button to select Days of The Week watering mode.
Water Days will be displayed at the bottom of the screen. With the
cursor on Monday, press the +button to activate the day or the –
button to cancel watering for that day. A indicates a water day, and
a _indicates a non-water day. After pressing the + / – button on a
specic day the cursor will automatically move to the next day. Press
the ▲or ▼buttons to move quickly to a specic day without making
a water or non water selection.
This is program specic so you will need to repeat these steps for each
required program.
Selecting Odd or Even Days to Water
This feature uses numbered days of the month for watering instead of
specic days of the week. (For example, Odd Days 1st, 3rd, 5th, etc. and
Even Days 2nd, 4th, 6th, etc.)
1. Turn the dial to SET DAYS TO WATER position.
2. Use the PRG button to select your desired program (A, B, C, or D).
3. Press the ◄ and ►button until Odd Days watering or Even Days
watering is shown on the display.
4. In either the Odd or Even Days mode, there will be a **NO WATER
DAYS** description ashing on the display. Within the Odd or Even
mode you can select days that watering will NOT take place. This is a
feature that is frequently used to omit watering on a specic day, for
example, a mowing day. Press the ▲or ▼buttons to move through
the days of the week and press the +button for the days that you DO
NOT want to water. By pressing the +button on a specic day, an X
will appear indicting that the day is a Non-Water Day.
5. To change a Non-Water Day, use the ▲or ▼buttons to go to that
day and press the –button. The Xwill disappear, and the day will be
available for Odd or Even watering again.
NOTE: The 31st of any month and February 29th are
always “OFF” days when Odd watering is selected.
Selecting Interval Watering
This feature is convenient if you want to have a more consistent watering
schedule without having to worry about the day of the week or the date.
The interval number you select is the actual interval of days on which
watering will occur. For example, if you have an interval of 3 days watering
every third day. The days remaining (Remaining) indicates how many days
until the next watering occurs. For example, if you select interval 3 with 1
days remaining, watering will begin tomorrow at the scheduled time. At
midnight the days remaining will change from 1 to 0, indicating that the
controller will water that day.
1. Turn the dial to the SET DAYS TO WATER position.
2. Use the PRG button to select your desired program
(A, B, C, or D).
3. Press the ◄ and ►button until Interval Days is displayed. The
Interval will be ashing. Use the + / – button to select the interval of
days on which watering will occur.
4. Press the ▼button once to program days remaining, if required. One
day remaining means it will begin watering the next day.
CONTROLLER PROGRAMMING (CONTINUED)
16

5. In the Interval Watering mode, there will be a No Water Days
description on the display. Within the Interval Watering mode you
can select days that watering will not take place. This is a feature that
is frequently used to omit watering on a specic day, for example, a
mowing day. Press the ▼button until the cursor points to Monday.
Once the cursor points to Monday the No Water Days description will
start ashing. Press the ▲or ▼buttons to move through the days of
the week and press the +button for the days that you DO NOT want
to water. By pressing the +button on a specic day, an Xwill appear
indicting that the day is a Non-Water day.
6. To change a No Water Day, use the ▲or ▼buttons to go to that
day and press the –button. The Xwill disappear, and the day will be
available for Interval watering again.
7. After programming water days, rotate the dial back to the RUN
position.
Set Seasonal Adjustment
Seasonal Adjustment is used to make run time changes without having to
reprogram all of the individual station run times. This feature is perfect for
making small changes that are necessary as weather conditions change due
to seasonality. For example, during hotter times of the year, your landscape
may require a bit more water. Seasonal adjust can be increased so that
stations will run longer than the programmed time. Conversely, as fall
approaches, the seasonal adjust can be reduced to allow for shorter station
watering durations.
There are three separate seasonal adjust modes that can be used
independently for each Program. Again, the selections are by program,
and the steps need to be taken for each program:
Global Seasonal Adjust (PRG Global) – This selection is a program global
seasonal adjustment, which increases or decreases station run times by
a xed %. All stations that have a run time within the Program will be
adjusted according to the Global Seasonal Adjust value.
1. Turn the dial to SET SEASONAL ADJUSTMENT. Use the PRG button
to select the desired program.
2. Press the + / – button to select the PRG Global seasonal adjust mode.
3. While in the PRG Global mode, press the ▼button and the
percentage will start ashing.
4. Press the + / – button to increase or decrease the global seasonal
adjust value between 0 and 300%, which will affect all the stations
within the program you have selected.
Monthly Seasonal Adjust (By Month) – All of the seasonal adjustment
values for the full year can be programmed into the controller at one time.
Each month, the controller will switch to the new seasonal adjust value.
1. Turn the dial to SET SEASONAL ADJUSTMENT. Use the PRG button
to select the desired program.
2. Press the + / – button to select By Month seasonal adjust mode.
3. While in the By Month mode, press the ▼button and the seasonal
adjust valve forJanuary will start ashing, and the ►cursor will
indicate January.
4. Press the + / – button to increase or decrease the seasonal adjust
value between 0 and 300% for the month selected, which will affect all
the stations for the Program you have selected.
5. By pressing the ▲or ▼buttons, you may scroll through the months to
select the specic month you want to adjust.
Solar Sync Adjust (By Solar Sync) – This mode allows seasonal adjustment
to occur on a daily basis when a Hunter Solar Sync is connected to the
controller. This provides for the maximum amount of water saving while
promoting healthy plant material. Solar Sync will change the seasonal
adjust % daily based upon weather conditions.
1. Turn the dial to SET SEASONAL ADJUSTMENT. Use the PRG button
to select the desired program.
2. Press the + / – button to select By Solar Sync seasonal adjust mode.
CONTROLLER PROGRAMMING (CONTINUED)
17

The Solar Sync will take over and the percentage will change according to
the ndings of the Solar Sync sensor. If you set seasonal adjust mode to
Solar Sync and you DO NOT have a Solar Sync connected, the controller
will automatically keep the seasonal adjust percentage at 100%.
There are also further steps in programming of the I-Core to assign the
Solar Sync, Rain, and Freeze sensor to shut down specic stations. This will
be detailed in this manual under Advanced Features, Sensor Conguration,
and Set Sensor Operation.
Set Pump Operation
The default is for all stations is Pump/Master Valve circuit ON. The Pump/
Master Valve circuit can be set ON or OFF by station, regardless of which
program the station is assigned. This feature may be utilized on systems
where it is desirable for a booster pump to operate with certain zones.
It could also be used for systems that have two points of connection and
some valves need a master valve/pump start to turn on and other valves
operate on a different water source that do not need the master valve/
pump start.
To Set Pump Operation:
1. Turn the dial to SET PUMP OPERATION position.
2. Press the ◄ and ►buttons to select a particular station.
3. Use the + / – button to turn the Pump/Master Valve circuit ON or OFF
for a specic station.
4. When nished, turn the dial back to the RUN position.
Cycle and Soak
The Cycle and Soak feature allows you to split a station’s run time into more
usable, shorter watering durations. This feature is useful when applying
water to slopes and tight soils because it automatically applies water more
slowly, helping to prevent run off from occurring. You should enter the
Cycle time as a fraction of the station’s watering time, and the Soak time as
the minimum number of minutes required before watering can occur again
for the next Cycle. The total number of cycles is determined by taking the
total programmed station run time and dividing it by the Cycle time.
Example: Station 1 requires 20 minutes of watering, but after 5 minutes,
runoff occurs. However, after 10 minutes all the water is absorbed.
The solution would be to program 20 minutes for the station run time,
5 minutes for the Cycle time, and 10 minutes for the Soak time.
1. Turn the dial to CYCLE AND SOAK position
2. Use the ◄ and ►buttons to select the station that you would like to
program Cycle and Soak.
3. Cycle will ash OFF. Use the + /– button to set the Cycle time. You
may select a maximum Cycle time of up to 60 minutes.
4. Press the ▼button to set the Soak time. Use the + /– button to set
the Soak time. You may select a maximum Soak time of up to 120
minutes.
5. Rotate the dial to the RUN position when nished programming all
Cycle and Soak times for yourdesired stations.
It may be benecial to understand how the cycle and soak application
process works. For example, Station 1 has been programmed to have a
5 minute cycle time and a 10 minute soak time. Station 1 may not exactly
come back on for its second cycle immediately after 10 minutes of soaking.
If there are other stations within the program that have run time after
Station 1, the program in numerical order will continue to run each station
that has a run time in the Program before it goes back to Station 1 for
another cycle. The Program will water each station for its programmed run
time or rst cycle time, before it looks back at station 1 to complete its
cycle and soak. If no other stations in the Program have a cycle and soak
programmed, then Station 1 will continue with its second cycle after all
stations have completed and then go into cycle and soak one after another
until the total run time has completed.
Set Sensor Operation
The SET SENSOR OPERATION dial position is specically used to set
a response for a sensor to a station. The I-Core controller is capable of
monitoring two individual Clik-type sensors, including the Solar Sync rain/
freeze sensor. You may have a combination of two Clik sensors, one Clik
sensor and one ow sensor, one Clik sensor and a Solar Sync rain/freeze
sensor, or two ow sensors. The I-Core Metal version controller has an
additional sensor terminal, allowing up to 3 sensors to be installed and
programmed. Additional programming assignment of the sensor(s) to
stations MUST be done in order for the sensors to shutdown irrigation.
The programming of the two available sensor inputs is described in the
Advanced Features section under Sensor Conguration (see pg. 22) and
must be completed prior to setting sensor operation.
NOTE: If using a Solar Sync it will show as a Clik sensor.
There is not a special distinction or selection for the
Solar Sync, and will be described as a Clik sensor for the
remainder of this section.
If two Clik sensors are installed, the display in the SET SENSOR
OPERATION dial position will allow you to program a response for each
sensor according to a particular station. A Sensor Response will either
show a  , indicating that the sensor will shut down irrigation, or _,
indicating that the station will ignore the state of the sensor and continue in
its normal operation.
NOTE: If using a Solar Sync, the Solar Sync sensor
terminal will automatically be used for both Rain and
Freeze inputs as well as weather adjustment
information. The display will show which sensor has
caused a shutdown.
