MOUNTING THE CONTROLLER TO WALL
NOTE: The indoor XC is not waterproof or weather resis-
tant, and must be installed indoors or in a protected area.
1. Secure one screw into the wall. Install screw anchors if attaching
to drywall or masonry wall.
2. Slide the keyhole on top of the controller over the screw.
3. Secure the controller in place by installing screws in the holes
below the terminal strip.
Do not plug transformer into power source until control-
ler is mounted and all valve wiring has been connected.
CONNECTING VALVES AND TRANSFORMER
Installation of the XC 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).
E – High Voltage Wiring (Outdoor Model only)
NOTE: XC outdoor models are water and weather resis-
tant. Connecting the outdoor XC 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.
1. Route AC power cable and conduit through the ½" (13mm) 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 junc-
tion box. AC supply wires must be 14 AWG (1.85mm) or larger
with appropriate circuit breaker for the wire size. A switch or cir-
cuit-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.
3. Replace the junction box cover.
ACTIVATING THE BATTERY
After installing your XC make sure to remove the bat-
tery contact insulator to allow the XC to keep time in
the event of a power outage.

REPLACING THE BATTERY
A high-energy lithium battery is included with your
XC controller. The battery allows the user to remotely
program the controller without connecting AC power.
It is also used to keep the current time and day during
power outage conditions. To replace the battery:
1. Remove the screw from the battery holder.
2. Slide the battery holder down to
access the battery.
3. Remove and replace the new battery
into the battery holder and reinstall the
battery holder.
NOTE: This positive (+) side of the battery should face
the inside of the battery holder.
Battery type: CR2032 3V
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.

CONNECTING A PUMP START RELAY
NOTE: Complete this section only if you have a pump
start relay installed. A pump start relay is 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 electri-
cal 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 Pterminal.
Relay holding current draw must not exceed .30 amps. Do not connect
the controller directly to the pump or damage to the controller will result.
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. Tighten each termi-
nal screw.

Mini-Clik®Rain Sensor
CONNECTING A WEATHER SENSOR
A Hunter weather sensor or other micro-switch type weather sensors
can be connected to the XC. 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 XC 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 ALL STATIONS cycle or by
activating the system using the One Touch MANUAL START (see page
10). 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.
POWER FAILURES
Due to the possibility of power failures, the controller has non-volatile
memory. Programmed information will never be lost due to a power
outage. The lithium battery will keep the correct time without AC
power. Normal watering will resume when AC power is restored.

PROGRAMMING THE CONTROLLER
The XC display shows the time and day when the controller is idle.
The display changes when the dial is rotated to indicate the specific
programming information to enter. When programming, the flash-
ing portion of the display can be changed by pressing the or
buttons. To change something that is not flashing, press the or
buttons until the desired field is flashing.
Three programs A, B, and C, each with the ability to have four daily
start times, permit plants with different watering requirements to be
separated on different day schedules.
NOTE: A basic programming rule is that whatever symbol
or character is flashing will be the item programmed. For
instance, if the hour is flashing when setting the time, the
hour can be changed or programmed. For illustration pur-
poses in this manual, flashing characters are in GRAY type.
Setting the Date and Time
1. Turn the dial to the CURRENT TIME/DAY position.
2. The current year will be flashing. Use the or
buttons to change the year. After setting
the year, press the button to proceed to
setting the month.
3. The month and day will be in the display.
The month will be flashing and the icon
will be displayed. Use the or buttons
to change the month. Press the button to
proceed to setting the day.
4. The day will be flashing and the icon
will be displayed. Use the or buttons
to change the day. Press the button to
proceed to setting the time.
5. The time will be displayed. Use the and
buttons to select AM, PM, or 24 hour.
Press the button to move to hours. Hours
will be flashing. Use the and buttons
to change the hour shown on the display.
Press the button to move to minute.
Minutes will be flashing. Use the and
buttons to change the minutes shown on the
display. The date, day, and time have now
been set.
Setting the Program Start Time(s)
1. Turn the dial to the START TIMES position.
2. The factory preset is set on program A. If
necessary, you can select program B, or C
by pressing the button.
3. Use the or button to change the
start time. (The start times advance in
15 minute increments).
4. Press the
button to add an additional start time, or button
for the next program.
NOTE: One start time will activate all stations sequential-
ly in that program. This eliminates the need to enter each
station’s start time. Multiple start times in a program
can be used for separate morning, afternoon, or evening
watering cycles. Start times may be entered in any order.
The XC will automatically sort them.
