Hunter ICC2 Modular 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.

A decoder system uses electronic modules (decoders) to control multiple irrigation valves over a two-wire path, enabling efficient and scalable irrigation management for large or complex sites.

Decoder systems are ideal for councils, sports fields, golf courses, commercial landscapes, and large residential projects needing flexible zone control and reduced wiring complexity.

Decoder systems reduce cable requirements, simplify installation and expansion, lower costs for large installations, and provide centralised, reliable valve control.

Typically no, a decoder controller is specifically manufactured for 2-wire decoder irrigation systems. So it’s a usually case of choosing one method or the other. However, hybrid systems do exist that incorporate both.

A two-wire cable is run from the controller, with decoders installed at each valve location. Each decoder is programmed with a unique address to operate its assigned valve.

Check for wire breaks, damaged insulation, or water ingress. Use a decoder system tester to identify faults, and ensure all decoders are securely connected and programmed.

All decoder systems come with manufacturer warranties and expert support from our team for system design, installation, programming, and troubleshooting.

Fully installed by a professional, a domestic irrigation system will come out to about $1000 per zone. And as a DIY project, it can look more like $300 per zone!

In rare applications, like on a wall under a well covered patio where the space is 100% dry all the time & not exposed to the sun, an indoor controller will continue to operate without issue. But if you’re not sure, we recommend installing an outdoor model. If something does go wrong with your controller due to water damage or the LCD screen failing from sun exposure, the warranty is voided so it’s not worth the risk.

Yes, irrigation controllers typically have a manual function, this will allow you to both operate all zones, or each one individually as you please.

Domestic irrigation controllers will always operate zones one at a time. Even if you try to operate 2 to come on at the same time, the controller will automatically delay the operation of the second zone until after the first zone has finished running.
