Hunter Pro-C/PCC Irrigation Controller

Introduction

Hunter Industries proudly presents the Pro-C irrigation controller family, designed for residential and light commercial use. The Pro-C offers simple, rotary-dial programming and a range of special features, developed with user needs in mind. This manual provides comprehensive guidance for installation, setup, and operation.

Parts of the Pro-C Controller (Indoor Model)

The Pro-C controller features a liquid crystal display (LCD) and a rotary dial for easy programming. Key components include:

• LCD Display: Shows program selection, zone number, current time, date, and various status indicators (e.g., watering in progress, sensor status).
• Zone Number Indicator: Displays the currently selected zone.
• Display Area: Shows all programmed features.
• Year, Month, Day Indicators: For date settings.
• Watering Indicator: Symbol indicating that watering is in progress.
• Day of the Week Indicators: Shows which days are programmed for watering (Mon-Sun), including options for odd/even day watering and interval watering.
• Odd/Even Day Indicator: Shows if odd or even day watering is selected.
• Interval Watering Indicator: Shows if interval watering is selected.
• Seasonal Adjust Scale: Indicates the percentage adjustment for watering duration (5% to 300%).
• Start Time Indicator: Helps identify the selected start time when the dial is in the Start Time position.

Control Buttons:

• + / - Buttons: Increase or decrease displayed values.
• ▶️ (Enter/Next) Button: Moves to the next value or setting.
• PRG Button: Cycles through programs A, B, and C, or initiates a test program.
• MANUAL START / PRESS & HOLD Button: Initiates manual watering for a zone or the entire program.
• Rain Sensor Switch: Allows bypassing or enabling the connected rain sensor.

Rotary Dial Positions:

• OFF: Turns off automatic operation.
• AUTO: Normal automatic and manual operation mode.
• SET TIME & DATE: For setting the current time and date.
• START TIMES: To set up to four start times per program.
• WATERING DAYS: To select watering days (specific days, interval, odd/even).
• WATER BUDGET (Seasonal Adjust): To adjust watering duration by percentage.
• RUN TIMES: To set the duration for each zone's watering.
• PUMP/MASTER VALVE: To connect and control a pump or master valve.
• RAIN DELAY: To set a delay for rain sensor activation.

Parts of the Pro-C Controller (Connection Box)

The connection box houses the wiring terminals and modules:

• 9V Battery Compartment: For programming without main power (battery not included).
• Reset Button: Resets the controller to factory defaults.
• Power Module: Connects the power supply, rain sensors, and accessory units.
• Power Supply: Transformer for indoor models (plug-in) or connection for outdoor models.
• Expansion Module Slots: For adding more zones (PCM-300, PCM-900 modules).
• Base Module: Contains connections for the first three zones, pump/master valve, and common wire.
• Module Retaining Lock (Easy-Lock™): Secures expansion modules.
• Common Wire Terminal: For connecting the common wire from valves.
• Zone Wire Terminals: For connecting individual zone wires (numbered 1-12 or 1-15 depending on modules).
• P/MV Terminal: For pump or master valve connection.
• SEN Terminals: For connecting rain sensors.
• REM Terminal: For connecting remote control devices.
• 24VAC Terminals: For power supply connection.
• Ground Screw: For grounding the unit.

Installation and Wiring

Connecting Valves and Transformer:

Use multi-strand, direct-burial irrigation wire with at least 0.8-1 mm diameter. Connect the common wire of all solenoids to the common wire terminal (typically green/yellow). Connect the other wire of each solenoid to a dedicated zone terminal (1, 2, 3, etc.). Use waterproof connectors for all wire splices.

Transformer Connection:

• Indoor Model: Connect the transformer's wires to the AC terminals on the controller. The transformer typically plugs into a wall outlet.
• Outdoor Model: The transformer is housed within the controller. Connect the 230V AC mains supply to the designated terminals, ensuring proper strain relief and moisture protection (e.g., using a cable gland).

Master Valve/Pump Relay Connection:

Connect the master valve or pump relay solenoid wires to the 'P/MV' terminal and the 'Common' terminal. Ensure the relay or valve does not exceed the controller's current rating (0.28 Amps for the solenoid).

Rain Sensor Connection:

Connect the rain sensor wires to the 'SEN' terminals. The controller can bypass the rain sensor using the 'RAIN SENSOR' switch on the dial. If no sensor is connected and the switch is enabled, watering will be blocked.

Remote Control Connection (ROAM/ICR):

Requires a SmartPort® accessory. Connect the SmartPort® to the controller's REM terminal and the appropriate wires (red, white, blue) to AC1, AC2, and REM terminals respectively. Follow the SmartPort® manual for detailed instructions.

Controller Setup and Operation

The Pro-C controller allows for flexible programming using three independent programs (A, B, C), each with up to four start times per day.

Basic Setup Principles:

• Start Times: Set when watering should begin. One start time can run multiple zones sequentially.
• Run Times: Set how long each zone waters (1 minute to 6 hours).
• Watering Days: Select specific days, interval watering (e.g., every 3 days), or odd/even day watering.

Programming Steps:

1. Set Time and Date: Turn the dial to 'SET TIME & DATE'. Use the +/- and Enter buttons to set the year, month, day, hour, and minute. Select AM/PM or 24-hour format.
2. Set Start Times: Turn the dial to 'START TIMES'. Select program A, B, or C using the PRG button. Set the desired start time(s) using +/- and Enter. Multiple start times per program allow for different watering schedules within the same program (e.g., morning and evening).
3. Set Run Times: Turn the dial to 'RUN TIMES'. Select the program (A, B, C) and zone. Use +/- buttons to set the watering duration for each zone. 'OFF' can be used to skip a zone for that program.
4. Set Watering Days: Turn the dial to 'WATERING DAYS'. Select program A, B, or C. Choose between:
• Specific Days: Use +/- buttons to select days of the week (Mon-Sun).
• Interval Watering: Set the number of days between watering cycles.
• Odd/Even Days: Select watering on odd or even-numbered days of the month.
5. Seasonal Adjust (Water Budget): Turn the dial to 'WATER BUDGET'. Use +/- buttons to adjust the watering duration for all zones simultaneously by a percentage (5% to 300%). This is useful for adapting to seasonal weather changes without reprogramming individual run times.
6. Pump/Master Valve: Turn the dial to 'PUMP/MASTER VALVE'. Enable or disable the pump/master valve for each zone individually.
7. Rain Sensor Bypass: The 'RAIN SENSOR' switch on the dial allows bypassing the rain sensor if needed.
8. Manual Operation: Use the 'MANUAL START' button to run a specific zone or the entire program manually.
9. Test Program: Access via the PRG button while turning the dial to 'START TIMES'. Allows testing of zones and their run times.
10. Resetting the Controller: Hold PRG, press and release the reset button on the back of the unit, wait for '12:00 AM' on the display, then release PRG. This erases all programming.

Advanced Features

• Multiple Programs: Use programs A, B, and C independently for different watering needs (e.g., lawn, flower beds, shrubs).
• Sensor Override Programming: Program specific zones to ignore the rain sensor if they are in sheltered areas and still require watering after rain.
• Zone Delay: Program a delay between zone activations, useful for systems with slow-closing valves or low water pressure.
• Save/Load Programs: Save current settings to memory and load them later.
• Quick Check™ System: Built-in diagnostic tool to check wiring and solenoids for shorts or faults.
