Need more zones for your Hunter Pro-C sprinkler system? This PCM1600 expansion module adds 16 extra stations to your existing PC-400 or HPC-400 controller. Since the base timer has 4 zones, adding this module (and possibly a PCM300) can bring you up to 23 zones total. It's a genuine Hunter OEM part, so it plugs right in and works seamlessly. The new black version is compatible with older gray modules. Perfect if you've expanded your landscape or added drip irrigation lines. Installation is straightforward – just power down the controller, plug it into the expansion port, and configure your zones. Keep your lawn and garden watered efficiently with more control.
