CONNECTING VALVES AND TRANSFORMER
Installation of the X-Core should only be done by trained personnel.
1. Route valve wires between the control valve location and controller.
2. At valves, attach a common wire to either solenoid wire on all
valves. This is most commonly a white colored wire. Attach a
separate control wire to the remaining wire of each valve. All wire
connections should be done using waterproof connectors.
3. Route the valve wires through the conduit. Attach the conduit
through the bottom right side of the controller.
4. Secure the white valve common wire to the C (Common) screw on
the terminal strip. Attach each of the individual valve control wires
to the appropriate station terminals and tighten their screws.
5. Indoor Models: route the transformer cable through the hole on
the left side of the controller and connect the wires to the two
screws marked 24VAC.
Outdoor Models: transformer wires are already connected to the
AC terminals so all that is required is to connect primary power to
the junction box (see below).
NOTE: X-Core outdoor models are water and
weather resistant. Connecting the outdoor X-Core
to primary AC power should only be done by a
licensed electrician following all local codes. Improper
installation could result in shock or fire hazard.
BAT
High Voltage Wiring (Outdoor Model only)
1. Route AC power cable and conduit through the ½" (13 mm)
conduit opening on the left side bottom of the cabinet.
2. Connect one wire to each of the two wires inside the junction
box. The ground wire should be connected to the green wire.
Wire nuts are provided to make these connections.
Note: For –E models only: Connect the wires to the AC
terminal block inside the junction box. AC supply wires must
be 14 AWG (1.85 mm) or larger with appropriate circuit
breaker for the wire size. A switch or circuit-breaker shall be
included in the building installation (in close proximity to the
controller, within easy reach of the operator) and marked as
the disconnecting device for the equipment.

CONNECTING A MASTER VALVE
NOTE: Complete this section only if you have a
master valve installed in your irrigation system. A
master valve is a “normally closed” valve installed
at the supply point of the main line that opens only
when the controller initiates a watering program.
1.
At the Master Valve, attach the common wire to either solenoid
wire of the valve. Attach a separate control wire to the remaining
solenoid wire.
2. The common wire should be attached to the Cterminal inside
the controller. The other wire coming from the master valve
should be attached to the Pterminal inside the controller.

a device that uses a signal from the controller to
actuate a separate electrical circuit to energize a
pump to provide water to your system.
The controller should be mounted at least a 15 ft (4.5 m) away from
both the pump start relay and pump to minimize any potential
electrical interference.
1. Route a pair of wires from the pump relay into the controller.
2. Connect a common wire to the C(Common) terminal inside the
controller and connect the remaining wire from the pump start
relay to the P(Pump) terminal.
Relay holding current draw must not exceed 0.3 A. Do not connect
the controller directly to the pump or damage to the controller will
result.
CONNECTING A PUMP START RELAY

11
CONNECTING A HUNTER “CLIK” WEATHER SENSOR
A Hunter weather sensor or other micro-switch type weather
sensors can be connected to the X-Core. The purpose of this sensor
is to stop automatic watering when weather conditions dictate.
1. Remove the metal jumper plate that is attached across the two
SEN terminals inside the controller.
2. Connect one wire to one SEN terminal and the other wire to the
other SEN terminal.
When the weather sensor has
deactivated automatic watering,
the OFF, and icon will appear
on the display.
Testing the Weather Sensor
The X-Core provides simplified testing of a rain sensor when the
sensor is wired into the sensor circuit. You can manually test proper
operation of the rain sensor by running a MANUAL CYCLE or by
activating the system using the One Touch MANUAL START (see
page 22). During the Manual cycle, pressing the test button on the
Mini-Clik®will interrupt watering.
Manually Bypassing the Weather Sensor
If the rain sensor is interrupting irrigation,
you can bypass it by using the bypass
switch on the front of the controller. Slide
the switch to the SENSOR BYPASS position
to disable the rain sensor from the system
to allow for controller operation. You can
also bypass the weather sensor for manual
operation by using the MANUAL – ONE STATION function.
The Bypass switch does not affect the Seasonal Adjust update
when using Solar Sync sensor.

CONNECTING A HUNTER SOLAR SYNC ET SENSOR
The X-Core is compatible with the Solar Sync and Wireless Solar
Sync systems. Solar Sync is a sensor system that will automatically
adjust the X-Core controller’s watering schedule (based on
changes in local climate condition) by using the Seasonal Adjust
function. The Solar Sync uses a solar and temperature sensor to
determine evapotranspiration (ET), or the rate at which plants and
turf use water, and also includes Hunter Rain Clik and Freeze Clik
technology that will shut down irrigation when it rains and/or during
freezing conditions.
NOTE: Solar Sync will apply a default seasonal adjust
value of 100% until the first full day (24 hour period)
of weather measurements have been received from
the sensor.
NOTE: Enabling the Sensor Bypass switch has no
effect on the seasonal adjust updates from the Solar
Sync sensor. It will, however, bypass the Rain Clik and
Freeze Clik functionality of the sensor.
Installing Solar Sync Sensor
Connect the Green and Black wire from the Solar Sync Sensor to
the “SEN” wiring terminals on the X-Core controller, similar to
picture on page 11. It does not matter which wire connects to which
terminal. Turn the dial to the “Solar Sync Settings” position. The
display will initially show dashed lines
and then will show the default Region
setting (3) on the left and the default
Water Adjustment setting (5) on the
right. Adjust the Region as needed
by using the and buttons (refer to page 13 for explanation
of Solar Sync Region setting). Use the button to advance to the
right to adjust the Water Adjust setting as needed (see page 14 for
explanation of Water Adjust setting).
Installing the Wireless Solar Sync
Connect the Green and Black wire from the Wireless Solar Sync
Receiver to the “SEN” wiring terminals on the X-Core controller. It
does not matter which wire connects to which terminal. Turn the dial
to the “Solar Sync Settings” position. The display will initially show
dashed lines and then will show the default Region setting (3) on
the left and the default Water Adjustment setting (5) on the right.
Adjust the region as needed by using the and buttons (refer
to page 13 for explanation of Solar
Sync Region setting). Use the button
to advance to the right to adjust the
Water Adjust setting as needed (see
page 14 for explanation of Water
Adjust setting).
Solar Sync Settings
Once the Solar Sync sensor is connected to the X-Core controller,
two numbers will appear in the display when the dial is turned to
the Solar Sync Settings position. The number on the left of the
screen is the Region setting, and the number on the right on the
screen is the Water Adjustment setting (as shown above).

Region

For accurate Solar Sync measurements, the controller needs to
be programmed for the average peak season ET for your region.
Use the table below to determine your region.
The table will assist you in identifying the type of region you live
in. There are four basic ET regions, each with descriptions of the
region, along with typical ET and temperature characteristics. It is
recommended that, if possible, the region be chosen based upon
average July ET or peak summer ET (inches/mm per day).
Use the following table for choosing your region (reference below).
You can use methods A, Bor Cto help you choose which region is
best for your area:
A: Based upon the ET of your region using the average July ET
or peak summer ET (inches/mm per day). This is the preferred
option when selecting your region.
B: Based upon the temperature for your region using the average
July or the driest month high temperature (not the highest
temperature for July).
C: Based upon the general description of your region.
• U.S. Northern States
• Coastal Regions
If the average July ET is
< 0.17" (4.3 mm) per day
If the average temperature for July is
65°– 75°
(18°C – 24°C)
If the average temperature for July is
75° – 85°
(24°C – 29°C)
• Mountains
• U.S. Northern Inland States
If the average July ET is 0.18" – 0.23"
(4.6 mm – 5.8 mm) per day
• U.S. Southern States
• Inland/High Desert
If the average July ET is 0.24" – 0.29"
(6.1 mm – 7.4 mm) per day
If the average temperature for July is
85° – 95°

CONNECTING A HUNTER SOLAR SYNC ET SENSOR
Water Adjustment

The Water Adjustment is a 1 to 10 scale that allows for easy
adjustment of the Seasonal Adjust value from the Solar Sync
ET Sensor. Upon installation of the Solar Sync ET Sensor, it is
recommended that the Water Adjustment setting stay at the default
value of 5. However, after installation, if you find that the seasonal
adjust value is lower or higher than expected, the Water Adjustment
value can be modified to modify the Seasonal Adjust output value.
See Calibration/Setup on page 15 for explanation of how to use
Water Adjustment scale to fine tune seasonal adjust output value.
NOTE: If an individual zone is “wetter” or “drier”
than the rest of the system, simply increase or
decrease the amount of run time on the controller.
Uninstalling a Solar Sync Sensor
If a Solar Sync sensor has been installed on the X-Core controller
then the seasonal adjust value used by the controller will be
calculated from the weather data supplied by the Solar Sync sensor.
If it is decided that the Solar Sync sensor will no longer be used
with the X-Core controller, it must be uninstalled. If the Solar
Sync sensor is not uninstalled, the controller will not allow the
seasonal adjust value to be manually changed. For example, if the
seasonal adjust value shown on the controller was 50% when the
Solar Sync sensor was removed, it will remain 50% until the Solar
Sync sensor is uninstalled.
To uninstall the Solar Sync sensor, simply disconnect the green and
black wires from the controller terminal and then turn the dial to the
“Solar Sync Settings” position. The display should show dashes,
indicating that the controller no longer recognizes the Solar Sync
sensor for calculation of seasonal adjustment. Now the seasonal
adjust value can be changed manually by turning the knob to the
“Seasonal Adjust” position and using the or button to adjust
the value.

15
CONNECTING A HUNTER SOLAR SYNC ET SENSOR
Calibration/Setup
After Solar Sync has been installed and programmed, it is recommended to allow the system to run for a few days at the initial setting.
Because of the variety in site conditions (including sensor location, amount of direct sunlight available to the sensor, reflective heat from
surrounding structures, etc), the initial setting may require adjustment in order to arrive at the desired performance. The calibration
of the Solar Sync to a particular site can easily be accomplished by adjusting the Region and/or Water Adjustment settings. The instructions
below outline this process:
1. Install Solar Sync sensor
2. Program Region and allow system to operate at initial setting for a minimum of 3 days (see page 13 for instructions on how to determine
proper Region setting).
3. Observe the Seasonal Adjust on the controller. If the Seasonal Adjust amount appears to be lower or higher than expected for that time
of year, the Solar Sync settings need to be adjusted.
a. Seasonal Adjust too low: Turn the dial to the Solar Sync settings position. Increase the value on the Water Adjustment scale (10 is max).
Once the setting is changed, the controller will immediately be updated with the new Seasonal Adjust %. Increase the Water Adjustment
setting until the desired Seasonal Adjust % is shown. If you max out the Water Adjustment scale at 10 and still require more Seasonal
Adjust, move down to the next lower Region (from Region 4 to 3, for example).
b. Seasonal Adjust too high: Turn the dial to the Solar Sync settings position. Decrease the value on the Water Adjustment scale (default
setting is 5). Once the setting is changed, the controller will immediately be updated with the new Seasonal Adjust %. Decrease the Water
Adjustment setting until the desired Seasonal Adjust % is shown. If you minimize the Water Adjustment scale down to 1 and still require
a reduction in Seasonal Adjust, move up the next Region (from Region 2 to 3, for example).
Station Run Times: It is important to understand that Solar Sync provides a global seasonal adjustment to the controller. This means that
all station run times will be modified by the seasonal adjust percentage shown. When programming the controller, the run times should be
entered that represent peak season watering schedules. If the Solar Sync is adjusting to the appropriate seasonal adjust value but the run
time for a particular station appears to be too long/short, adjust the station run time in the controller program.
