MOUNTING THE CONTROLLER TO A WALL

1. Select a location close to an electrical outlet or power supply that is not controlled by a light switch.
2. Remove the front panel from the Pro-C by first removing the ribbon connector and then pulling down the hinge release. Removing the
   front panel will ease the installation of the controller cabinet.
3. Use the hole at the top of the controller as a reference and secure a 1″ (25 mm) screw (A) into the wall. Note: Install screw anchors if
   attaching to drywall or masonry wall.
4. Align controller with the screw and slide the keyhole (B) on top of the controller over the screw.
5. Secure controller in place by installing screws in the holes (C).

Connecting VALVES and AC Power

1. Route valve wires between the control valve location and the controller.
2. At the valves, attach a common wire to either solenoid wire of all valves. This is most commonly a white colored wire. Attach a separate
   control wire to the remaining wire of each valve. All wire splice connections should be done using waterproof connectors.
3. Route valve wires through the conduit and attach the conduit to one of the openings on the bottom of the cabinet.
4. Strip ½” (13 mm) of insulation from the ends of all wires. Secure the valve common wire to the “COM” (Common) terminal. Attach all individual valve control wires to the appropriate station terminals.

Indoor Cabinet

• Route transformer cable through the hole on the bottom left side of the controller and connect one Yellow Wire to each of the screws marked AC and the Green Wire to GND

Outdoor Cabinet

• Route AC power cable and conduit through the ½” (13 mm) conduit opening on the left side of the bottom of the cabinet. Connect the wires to the transformer wires located inside the junction box. International units are supplied with a built-in terminal strip. Always use a UL-listed conduit ½” (13 mm) male adapter when installing the AC wiring. Insert the adapter into the ½” (13 mm) hole at the bottom of the controller. Attach a nut to the adapter inside the enclosure.

INS TALLING STATION MODULES

• The Pro-C controller is supplied with a factory-installed base module for up to 3 stations. Additional modules may be added in increments of 3 stations (PCM-300) or a single 9-station (PCM-900) to expand the controller’s station capability to 15 stations. Additional modules are sold separately.
• The Pro-C utilizes automatic module recognition firmware to identify when PCM modules are installed or removed from the controller. This feature will recognize the correct number of stations without having to reset or cycle power to the controller.

Installing PCM Modules

The Pro-C controller is designed with a simple-to-use Power Lock feature that assures that the modules are energized and firmly secured into the controller. The Power Lock can unlock or lock all modules at one time by simply pushing the Power Lock slide.

1. Slide the Power Lock into the Power Off (unlocked) position. Insert the PCM modules into the appropriate sequential position in the
   controller cabinet.
   Note: Your Pro-C controller is designed to work only in conjunction with BLACK PCM expansion modules.
2. Once all of the modules are in place, slide the Power Lock into the Power On (locked) position to energize and secure the modules into the controller.
3. The Pro-C will automatically recognize the correct number of stations. It is not necessary to press the reset button or cycle power to the controller

CONNECTING A Master Valve

1. At the Master Valve, attach the common wire to either solenoid wire of the valve. Attach a separate control wire to the remaining
   solenoid wire.
2. Route the wires into the controller.
3. Connect either wire from the Master Valve to the P/MV terminal. Connect a remaining wire to the “COM” (Common) terminal

CONNECTING A PUMP START RELAY

1. Route a wire pair from the pump relay into the controller housing.
2. Connect the pump common wire to the terminal slot “COM” (Common) and the remaining wire from the pump relay to the P/MV screw slot.
   • Relay holding current draw must not exceed .28 amps (24 VAC). Do not connect the controller directly to the pump – damage to the controller will result.

CONNECTING A WEATHER SENSOR (not included)

A Hunter Mini-Clik® rain sensor or other type of micro-switch weather sensor may be connected to the Pro-C. The purpose of a rain sensor is to stop watering when precipitation is sufficient.

1. Route the wires from the rain sensor up through the same conduit used for valve wiring.
2. Remove the metal jumper plate from the two SEN terminals.
3. Connect one wire to the SEN terminal and one to the other SEN terminal.
4. When the weather sensor has deactivated automatic watering, OFF and the sensor will appear on the display.

Manually Bypassing the Weather Sensor

• If the rain sensor is interrupting irrigation, you can bypass it by using the bypass switch on he front of the controller. Slide the switch to the SENSOR BYPASS position to disable the rain sensor from the system and allow the controller to operate. You can also bypass the weather sensor for manual operation by using the MANUAL – SINGLE STATION function

CONNECTING TO THE HUNTER SOLAR SYNC

• The Solar Sync is a sensor system that, when connected to Hunter Pro-C, will automatically adjust your controller’s watering based on changes in local climate conditions. The Solar Sync utilizes a solar and temperature sensor to measure on-site weather conditions used to determine evapotranspiration (ET), or the rate at which plants and turf use water. In addition, the Solar Sync sensor includes a Hunter Rain-Clik™ and Freeze-Clik™ sensor that will shut down your irrigation system when it rains and/or during freezing conditions.
• A small module connects the sensor to the controller and will automatically increase or decrease watering run times based on weather changes. The result is a new water-efficient irrigation product that promotes water conservation and healthier plants. You simply
  program your controller like you normally would, and the Solar Sync takes over from there, eliminating the need to manually adjust your watering schedule.

POWER FAILURES

• Due to the possibility of power failures, the controller has non‑volatile memory to preserve the program indefinitely. There is no default program. The Pro-C is also capable of keeping the current time and date for an extended period during power outage conditions.

SPRINKLER SYSTEM FUNDAMENTALS

• There are three main components that are involved in all automatic sprinkler systems that are made today. They are the controller, valves, and sprinklers.
• The controller is what makes the whole system operate efficiently. It is technically the brain of the entire system, instructing the valves when to supply water to the sprinklers and for how long to do so. The sprinklers, in turn, will direct the water towards the surrounding plants and lawn. A valve controls a group of sprinklers called a watering station.
• These stations are laid out in a fashion according to the type of plant, the locations of the plants, and the maximum amount of water that can be pumped to the location. Each valve is connected via wire to the controller. Here, the wire is connected to a number that corresponds to the valve’s station number
• Valve 1 – Activates Station 1 – Rotors water front yard lawn
• Valve 2 – Activates Station 2 – Sprays water side lawn and the bubblers water flowers
• Valve 3 – Activates Station 3 – Rotors water back yard lawn
• Valve 4 – Activates Station 4 – Bubblers water garden
• Valve 5 – Activates Station 5 – Sprays water side lawn and bubbles water flowers
• Valve 6 – Activates Station 6 – Sprays water front corner lawn

CREATING A WATERING SCHEDULE

There are some guidelines that should be followed when determining when and how long to water. These factors are the soil type, the part
of the landscape being watered, weather conditions, and the types of sprinklers being used. A watering schedule form is included with your
Pro-C can be used as a handy reference.

• Station Number and Location – Identify the station number, location and the type of plant that is being watered.
• Watering Day – Identify whether you want to use a calendar day, interval, or an odd or even day schedule. For a calendar day schedule, circle the day of the week in which watering is desired. For an interval schedule, indicate the desired interval number.

PROGRAMMING FUNDAMENTALS

1. Select a program (A, B, or C) by pressing the button on the controller (it is recommended to start with Program A).
2. Set a program start time (only one program start time is required to activate a watering program).
3. Set the run time for each valve assigned to the program, and
4. Set the days that you would like the watering program to run.
   • We have included an example that will better illustrate the operation of a program:
   • Let’s say you have a program start time set for 6:00 a.m. Stations 1 and 2 are going to have a run time of 15 minutes, and Station 3 is set for 20 minutes. Please note that stations 4, 5, etc. have not been included in this program; we will water them in separate programs.
   • At 6:00 a.m., the controller will activate the watering cycle. The sprinklers on Station 1 will run for 15 minutes and then shut off. The controller will automatically advance to station 2 sprinklers. These sprinklers will also run for 15 minutes and then shut off. Then, watering on station 3 will begin. The sprinklers will turn on for 20 minutes and shut off. Since no times were programmed for stations 4, 5, etc. the controller skips them. This will conclude the program and end the water cycle at 6:50 a.m
