If you are looking for an affordable yet full-featured way to automatically water your plants, lawns, and gardens, the Hunter Pro-C Irrigation Timer is an industry-leading choice. Engineered for both residential and light commercial applications, this modular AC controller starts with 4 base stations but can be seamlessly expanded up to 16 stations as your landscape grows. By pairing the Hunter Pro-C with an irrigation filter to protect your system and 24V AC irrigation valves, you can achieve professional-grade automation with exceptional reliability.
Available in both an indoor plug-in model and an outdoor hardwired model, the Pro-C is incredibly easy to wire and use. It features a large, highly visible LCD display and intuitive dial programming. You can set up to three independent programs, customize delays between stations for slow-closing valves, and easily implement rain delays during wet weather. With compatibility for optional remote controls and weather stations, plus a non-volatile memory that requires absolutely no backup battery, the Hunter Pro-C delivers long-lasting convenience and precise water management.

Get your modular AC controller running smoothly.
Step 1: Mount & Connect Power
For the indoor model (PC-300i), mount to an interior wall and plug into a standard 110V outlet. For the outdoor model (PC-300), mount the weather-resistant cabinet externally and hardwire the transformer directly to your AC electrical supply (professional installation recommended).
Step 2: Install Expansion Modules (Optional)
If you are running more than 4 zones, slide your compatible Hunter PCM expansion modules into the open slots to expand your capacity up to 16 stations.
Step 3: Wire the Valves
Run multi-strand wire from your 24V AC valve manifolds to the controller. Connect the common wire to the 'COM' terminal and individual valve wires to the numbered station terminals.
Step 4: Program via Dial
Use the intuitive dial and large LCD interface to set the current time, date, watering days, and run times for your independent programs.
Do I need to install a backup battery in the Hunter Pro-C?
No, the Hunter Pro-C features advanced non-volatile memory that securely stores all of your programming and time/date settings. A backup battery is not necessary, completely eliminating routine battery maintenance.
Even during prolonged power outages, your schedules will remain safe and ready to resume once power is restored.
What is the difference between the indoor and outdoor models?
The Indoor model (PC-300i) features a standard 110V plug and is meant for dry, interior locations like a garage. The Outdoor model (PC-300) features a weatherproof locking cabinet and an internal transformer that must be hardwired directly into your electrical system.
Both models share the exact same programming interface and 4-to-16 station expandability.
What valves work with the Hunter Pro-C controller?
This AC controller must be paired with standard 24V AC irrigation valves. It will not operate DC latching solenoids commonly used with battery-operated timers.
Ensure all valves in your system manifold are strictly AC-compatible before wiring them into the station terminals.
How should I prepare my Hunter Pro-C for spring watering?
Prepare the Hunter Pro-C for spring by checking your AC valve wiring connections, manually testing each zone to ensure valves open properly, and setting a conservative early-season schedule.
If you experience heavy spring showers, you can easily activate the programmable rain delay feature to pause watering for a set number of days without altering your permanent schedule.
