EZ Decoders are small, waterproof and come with color-coded wiring and a convenient LED status light. They do not require special wire or connectors to function. Better yet, the system can coexist with conventional output modules, allowing hybrid functionality of both direct-wired valves and decoder operations in the same controller. This technology also permits easy conversion of a conventionally wired system to two-wire using the existing wiring bundle. It's that easy.
