Decoder Controllers

A decoder controller is an advanced irrigation controller that communicates with multiple valve decoders over a two-wire path, enabling efficient management of large, multi-zone irrigation systems.

Decoder controllers are ideal for councils, sports grounds, commercial landscapes, golf courses, and any large property where scalable, centralised irrigation management is needed.

Typically no. Stick with matching Brands & their compatible models. In the event where you’re forced to consider a mismatch, check compatibility between your equipment and decoder models & seek advice from our expert team.

Each decoder is assigned a unique address, which you input into the controller. This lets you control each valve individually from the central unit.

Use a decoder line tester, check for short circuits, ensure all addresses are unique, and verify that all connections are weatherproof and corrosion-free.

You would consider a decoder controller over a traditional multi-core system if you are managing a large or complex irrigation project—such as a sports field, commercial landscape, golf course, or council site—where efficiency, scalability, and simplified wiring are important.
