Hunter LANKIT Ethernet Communication Module and Flow Monitoring for ICC2 Controllers ICC2 is a value-packed, light-to-mid size commercial irrigation controller that delivers more than you expect, just like its famous predecessor. It is designed to control larger projects (up to 54 stations) and offers the water savings you expect from a Hunter controller. ICC2 controllers are compatible with Centralus Irrigation Management Software, with three connectivity methods for a variety of applications (Wi-Fi, Ethernet, and 4G LTE Cellular). When adding Centralus to standalone ICC2 systems, users can also enable critical flow monitoring capabilities using HFS or HC Flow Meter sensors.
