Two-wire technology is often associated with gold courses or higher-end systems due to its perceived cost and complexity. However, with the High Station Count (HSC) controller and decoders, you get all the advantages of two-wire installations with smarter and faster technology. Now you can bring the power of two-wire control to more projects than ever before. Insert the High Station Count Single Station Field Decoder (HSC-FD1) in the Two-wire path wherever you need to add an irrigation valve. The HSC-FD1 can support any Husqvarna valve.  This is achieved by using AC power, the same AC power you are already experienced with, and is found in other traditional irrigation controllers. HSC-FD1 decoders are small waterproof decoders and best of all they do not require special wire or connectors to function! We do include DBR/Y connectors to provide additional peace of mind.
