Two wire is a technology that runs a single cable containing two wires from valve to valve without a home run for each valve. Valves are activated when the controller sends a signal along the pair of wires; each valve has a sensor that recognizes a unique signal sent by the controller. If you’ve ever installed a large system with home runs for each valve this system seems like magic; it’s offered by Hunter, Toro, etc.
