CONNECTING VALVES AND TRANSFORMERS
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 installa-
tion could result in shock or fire hazard.

Connect the two transformer
wires to the two AC Terminals
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 de-
vice for the equipment.
3. Replace the junction box cover.
