Connecting Valves and Transformer

Connecting Valves and Transformer - Route control wires between control valve location and controller. Typically it is recommended that an 18 AWG multi-wire sprinkler connection cable be used. This type of connection is insulated for burial and is color-coded to help keep track of your connections. At the valves, attach the common wire to either solenoid wire of the valve. This is most commonly the white colored wire. Attach a separate control wire to the remaining solenoid wire and make a note of the color corresponding to each valve and the watering station it controls. Secure the wires with a waterproof wire connector to protect the connection. Open hinged wiring compartment door to access the terminal strip area shown in the diagram. Route the valve wires through the large opening on the base of the cabinet or through inch conduit if installed. Strip inch of insulation from ends of all wires. Secure the white valve common wire to the screw on the terminal marked C. With the valve common wire connected, connect the color-coded wires from the valves to their appropriate station numbers and tighten the screws. Route transformer cable through the small hole in the bottom of the cabinet and connect the wires to the two screws marked AC. Do not plug transformer into power source until the controller is mounted and all valves have been connected.
