X-Core - Connecting Valves and Transformer

Installation of the X-Core should only be done by trained personnel.


Route valve wires between the control valve location and controller.


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.


Route the valve wires through the conduit. Attach the conduit through the bottom right side of the controller.


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.


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 (pictured)

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.

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.
