This Retro Panel Module Kit is compatible with Hunter's HCC. The HCC combines robust features of the popular ICC2 controller with automatic, weather-based daily adjustments of Hydrawise programming to create a smart and economical solution for commercial landscape management. HCC can control up to 54 stations* and effectively operate any two stations simultaneously. The controller’s convenient modular design allows for rapid expandability with the same 4-, 8-, and 22-station output modules as the ICC2. Engineered with a prewired SmartPort®, HCC is also compatible with Hunter’s ROAM and ROAM XL remotes, allowing for fast and reliable manual operation in the field from long-range distances without the need for a smartphone.
