Connecting Valves and AC Power

  1. Route valve wires between control valve location and controller.
  2. At valves, attach a common wire to either solenoid wire of all valves. This is most commonly a white colored wire. Attach a separate control wire to the remaining wire of each valve. All wire splice connections should be done using waterproof connectors.
  3. Open hinged faceplate on the controller to access the terminal strip area.
  4. Route valve wires through the conduit and attach conduit to the controller at the large conduit opening on the right side of the bottom of the cabinet. Refer to the conduit sizing chart on page 32 in the Frequently Asked Questions section if you are not sure what size conduit will work for your installation.
  5. Strip 1/2" (13 mm) of insulation from ends of all wires. Secure valve common wire to C (Common) terminal on the first module. Then attach all individual valve control wires to appropriate station terminals.

NOTE: It is usually best to connect all field wires prior to powering up the controller.

Indoor Cabinet

Route transformer cable through the left side of the controller and connect the wires to the screws marked AC. Before closing the compartment door make sure wires hang in the slotted areas so that the door can snap shut without damaging wires.

NOTE: It is recommended that a licensed electrician perform the following power installation.

Outdoor Cabinet

Route AC power cable and conduit through the 1/2" (13 mm) conduit opening on the left side of the bottom of the cabinet. Connect the wires to the transformer wires located inside the junction box. International units are supplied with a built in terminal strip. Always use a UL listed conduit 1/2" (13 mm) male adapter when installing the AC wiring. Insert the adapter (male threads first) into the 1/2" hole at the bottom of the controller until it enters the wiring enclosure. Attach the nut to the adapter inside the enclosure.

NOTE: Illustration shows international terminal strip. Domestic units are supplied with wires that must be connected with wire nuts or other locally approved connectors.
