Hunter ICM2200 22-Station Expansion Module with Enhanced Surge 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 can run any two of its four automatic programs simultaneously, providing flexible and efficient watering options. The ICC2 facepack and station output modules are also compatible with original ICC controllers, with upgrade kits available for retrofitting legacy ICC systems. 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.
