The Hunter PCM1600 is a genuine 16-station plug-in expansion module designed for use with Hunter Pro-C and HPC controllers. It provides a reliable, modular path to expand station capacity while preserving the Pro‑C’s proven programming and sensor features. Compatibility: Works with Hunter Pro‑C and HPC (Hydrawise) modular controllers to increase station capacity where needed. Capacity: Adds 16 conventional station outputs—expand your system from the base module up to the supported maximum. Modular plug-in design: Snap-in installation into the controller’s expansion bays for fast upgrades without complex rewiring. Auto-recognition: Controller will normally detect the added stations automatically; in rare cases a reset or power cycle may be required to complete recognition. Electrical specs: Designed for the Pro‑C/HPC system architecture (transformer output 24 VAC, 1 A; station output 0.56 A; P/MV output 0.28 A). Standards & approvals: Built to Hunter’s installation guidelines and listed with common agency approvals; suitable for residential and light-commercial use. Warranty: Backed by Hunter’s limited warranty (typically two years) for replacement or repair per manufacturer policy. Installation note: when expanding to 16 stations with a PCM‑1600, follow Hunter’s module placement instructions (install a PCM‑300 in the first expansion slot, then install the PCM‑1600 in the upper expansion slots) and secure the power lock before energizing. The PCM1600 is ideal for landscapers and homeowners who need a straightforward, durable expansion option that integrates with existing Pro‑C/HPC setups.
