Hunter PCM1600 16 Station Expansion Module Plug in Add On for Pro C and HPC Hydrawise Sprinkler Irrigation Controllers

The Hunter PCM1600 16 Station Expansion Module is the professional’s choice for upgrading and expanding Pro C and HPC Hydrawise irrigation controllers. This plug in add on module boosts system capacity to 23 stations with conventional wiring or up to 32 stations using the Hybrid EZ Decoder System, making it ideal for large residential, commercial, and municipal irrigation projects. Engineered for quick, precise installation, the PCM1600 fits into the upper two expansion slots of the controller. For 16 or 23 station configurations, a PCM300 module must be installed in the first expansion slot (stations 5–7) before adding the PCM1600. Designed exclusively for Pro C and HPC controllers, this module ensures a perfect fit, dependable communication, and long service life even in demanding outdoor environments. Contractors have full flexibility with six independent irrigation programs and up to six start times each, or advanced station-based programming for precise zone control. A dedicated P/MV output supports pump start relay and master valve activation. When paired with Hydrawise-enabled controllers, Predictive Watering technology uses local weather data from The Weather Company and Hydrawise Virtual Weather Stations to automatically adjust run times, reducing water waste and optimizing plant health. All Hydrawise-enabled controllers are EPA WaterSense and Smart WaterMark approved, delivering proven water savings and compliance. The PCM1600 is also compatible with optional HC Flow Meters, allowing automatic leak detection and alerts to prevent costly damage. Built to Hunter’s professional-grade standards, it’s the trusted choice for contractors who demand reliability, scalability, and performance in irrigation control.
