Our multi-wire controllers have a superb range of software features, enabling you to customise the controller match the exact needs of each installation.

Mi Models & Sizes

The Heron Mi range of controllers is available from 4 to 144 valves
• Base models are available in 4, 8, 12 & 16 valve options with fixed outputs
• The Mi144 irrigation controller operates 16 valves as standard, however it can be upgraded to operate a maximum of 144 valves using additional output cards. The additional output cards are available in 8 and 16 valve
models. The additional output cards are installed in expansion boxes.

Choose How You Want to Work

Heron’s Mi range of irrigation controllers can be operated in the following ways:-
• As a standalone controller
• From a PC using Heron’s Ground Control Software
• From a mobile device or PC using the WEB based APP

Easy to use

Heron’s multi-wire controllers are menu driven, making them intuitive and easy to use. Because every site is different, Heron multi-wire irrigation controllers can be configured to match the needs of each installation.
You can specify the number of programs, the type and number of automatic starts needed. Software features can be enabled or disabled as required.
Simply select the features you want to use from the list of options. The features will then appear in the controller’s main menu for you to use.

Complete Control

Your Irrigation sequence can be fully customised. Valves can be run in any order.
Valves within a sequence can be set to run in parallel.
To simplify the creation of irrigation sequences, valves can be individually named.

Our multi-wire irrigation controllers will integrate with the range of Heron sensors. Irrigation can be controlled by light, rain, temperature, humidity, soil moisture or wind direction.

Heron Controllers can also be connected to Heron fertiliser and acid dosing systems. Up to four dosing systems can be connected to one irrigation controller.
