Hunter Pro-C Controller

Outdoor or Indoor Models Available

The Pro-C controller is offered in both outdoor (weather-resistant) and indoor models, both listed with UL and CE certifications.

Modular Design

A single controller can be customized to support 3 to 15 stations by adding plug-in modules (PCM-300 for 3 stations, PCM-900 for 9 stations). This eliminates the need for contractors to stock multiple controller sizes. The modular design also simplifies service, allowing for easy replacement of primary power and station modules without removing the controller from the wall.

Easy Inventory Management

Contractors can stock one base controller and a supply of modules to meet various project needs, reducing inventory complexity.

Modular Design Eliminates Service Hassles

Damage from electrical surges (like lightning) can be isolated to specific modules, making repairs straightforward. Damaged modules can be easily extracted and replaced.

Future Expansion

The modular design allows for easy addition of stations as landscape projects expand.

Large LCD Display

A large, easy-to-read LCD display simplifies programming, schedule review, and verification, even in low light conditions. The display shows status indicators like STATION, START TIME, INTERVAL, PUMP RUN TIME, SENSOR, DAYS LEFT, PROGRAM, MONTH, DAY, YEAR, and day indicators (MON-SUN, ODD/EVEN).

Non-volatile Memory

Programs are stored indefinitely without the need for a backup battery. This memory retains all programs even during power failures or when AC power is suspended.

No Battery Required

The controller accurately tracks time of day for up to four weeks without AC power, thanks to its low power consumption circuitry.

Self-Diagnostic Electronic Short Circuit Protection

The Pro-C automatically skips shorted stations, preventing system shutdowns. It identifies faulty stations by displaying an "ERR" message along with the station number, aiding in field wiring problem diagnosis.

Intuitive Dial Programming

Step-by-step programming is facilitated by a dial and simple plus/minus/next buttons, making adjustments easy and intuitive.

Connecting Valves and AC Power

Route valve wires from control valves to the controller. Connect a common wire to all valve solenoids and individual control wires to each valve. Ensure all splices use waterproof connectors. Route valve wires through the conduit and connect them to the appropriate station terminals on the controller. For AC power, route the cable through the designated conduit opening and connect wires to the transformer terminals inside the junction box (outdoor) or to the AC screws (indoor). It is recommended that a licensed electrician perform the power installation.

Wiring Diagrams: Visual guides illustrate the connection of valve wires, common wires, and AC power for both indoor and outdoor cabinet installations.

Connecting Station Modules

The Pro-C comes with a base module for up to 3 stations. Additional 3-station (PCM-300) or 9-station (PCM-900) modules can be added to reach 15 stations. Modules are recognized automatically by the controller's firmware (for models manufactured after Nov. 2003). An Easy-Lock™ feature secures modules firmly.

Connecting the Battery (Optional)

A 9-volt battery can be installed to allow programming without AC power. The battery is not required for program retention due to non-volatile memory.

Connecting a Master Valve

Connect the common wire to one solenoid wire of the master valve and a control wire to the other. Route these wires to the controller and connect them to the P/MV and C (Common) terminals.

Connecting a Pump Start Relay

Mount the controller at least 15 feet (4.5 m) away from the pump start relay and pump. Connect a wire pair from the pump relay to the controller, with the common wire to the C (Common) terminal and the pump relay wire to the P/MV screw slot. Note: Relay holding current must not exceed 0.28 amps.
