MOUNTING THE CONTROLLER TO WALL
Note: The indoor version of the X-Core is not water-
proof or weather-resistant, 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.
NOTE:Do not plug transformer into power source until
controller is mounted and all valve wiring has
been connected.
NOTE: For XC - x01 - A: If the supply cord is damaged, it
must be replaced by the manufacturer or service agent,
or a similarly qualied person in order to
avoid hazard.
C
A
B
NOTE: The door on outdoor units must remain closed
for maximum water resistance.

9
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 le side of the controller and connect the wires to the two
screws marked 24 VAC.
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 throughout document. 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 re hazard.
High Voltage Wiring (Outdoor Model only)
1. Route AC power cable and conduit through the ½" (13 mm)
conduit opening on the le 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 discon-
necting device for the equipment.
3. Replace the junction box cover.

ACTIVATING THE BATTERY
REPLACING THE BATTERY
A high-energy lithium battery is included with your X-Core
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

Aer installing your X-Core, make sure to remove the battery
contact insulator to allow the X-Core to keep time in the event of
a power outage.
CAUTION:
RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN
INCORRECT TYPE. DISPOSE OF USED BATTERIES AC-
CORDING TO THE INSTRUCTIONS.
