For PC-301-A: If the supply cord is damaged, it must be replaced by the manufacturer or service agent or a similarly qualified person in order to avoid hazard.

Connecting Valves and AC Power

1. Route valve wires between control valve location and controller.
2. At 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. Open hinged faceplate on the controller to access the terminal strip area.
4. Route valve wires through the conduit and attach conduit to the controller at the large conduit opening on the right side of the bottom of the cabinet. Refer to the conduit sizing chart on page 32 in the Frequently Asked Questions section if you are not sure what size conduit will work for your installation.
5. Strip 1/2" (13 mm) of insulation from ends of all wires. Secure valve common wire to C (Common) terminal on the first module. Then attach all individual valve control wires to appropriate station terminals.

Indoor Cabinet

Route transformer cable through the left side of the controller and connect the wires to the screws marked AC. Before closing the compartment door make sure wires hang in the slotted areas so that the door can snap shut without damaging wires.

Diagram description: The controller's internal wiring terminals are shown. Transformer wires (black to AC1, black to AC2, green to GND) are connected. Valve wires are routed to specific station terminals (1-12), P/MV, and COM.

Outdoor Cabinet

Route AC power cable and conduit through the 1/2" (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 1/2" (13 mm) male adapter when installing the AC wiring. Insert the adapter (male threads first) into the 1/2" hole at the bottom of the controller until it enters the wiring enclosure. Attach the nut to the adapter inside the enclosure.

Diagram description: Shows AC power connections for 110 VAC and 230 or 250 VAC, and the routing of valve wires to the controller's terminals.

Connecting 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.

Note: The use of a PCM-900 to expand your controller to 15 stations requires that one PCM-300 be installed in the first slot (stations 4-6) and the PCM-900 in the upper two slots.

The Pro-C utilizes automatic module recognition firmware (Pro-C controllers manufactured Nov. 2003 and after) 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.

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

Note: The Easy-Lock feature was added to Pro-C controllers dated coded 12/01/02 or newer.

1. Slide the Easy-Lock into the unlock position. Insert the module(s) into the appropriate sequential position in the back of the controller.
2. Once all of the modules are in place, slide the Easy-Lock into the locked position to secure all 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 the power to the controller.

Diagram description: Shows PCM-300 and PCM-900 modules, and the controller's rear panel with module slots and the Easy-Lock slide in locked/unlocked positions.

Connecting the Battery for Programming Without AC Power (Optional)

Connect a 9-volt alkaline battery (not included) to the battery terminals and place in the battery compartment in the controller cabinet. The battery allows the user to program the controller without AC power. Watering will not occur without AC power. Since this controller has non-volatile memory, the program clock and calendar will be retained during a power outage even if no battery is installed.

Diagram description: Shows a 9-volt battery being connected to the battery terminals inside 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 via the field wire conduit.
3. Connect either wire from Master Valve to the P/MV terminal. Connect remaining wire to the C (Common) terminal.

Diagram description: Illustrates a master valve connected to the controller's P/MV and COM terminals, with valve wires and common wire shown.

Connecting a Pump Start Relay

The controller should be mounted at least 15 feet (4.5 m) away from both the pump start relay and the pump. When a pump is to be operated by the controller, a pump start relay must be used. Hunter offers a full range a pump start relays for most applications.

Relay holding current draw must not exceed .28 amps. Do not connect the controller directly to the pump – damage to controller will result.

1. Route a wire pair from the pump relay into the controller housing.
2. Connect a common wire to the terminal slot C (Common) and the remaining wire from the pump relay to the P/MV screw slot.

Diagram description: Shows the wiring connection between the controller, a pump start relay (PSR Series), and the pump, indicating a minimum distance of 15 feet (4.5 m).

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 this sensor is to stop watering when precipitation is sufficient. The sensor connects directly to the controller and allows you to easily override the sensor by using the Rain Sensor bypass switch on the controller.

1. Route the wires from the rain sensor up through the same conduit used for valve wiring.
2. Remove the jumper from the two SEN terminals.
3. Connect one wire to the SEN terminal and one to the other SEN terminal.

Diagram description: Shows a Mini-Clik® weather sensor connected to the controller's SEN terminals via sensor wires.

Connecting a Weather Sensor (Continued)

Testing a Weather Sensor

The Pro-C provides simplified testing of a rain sensor when the rain sensor is wired into the sensor circuit. It also provides the user the ability to override the rain sensor when necessary to perform system inspections and manual watering.

• Testing the Rain Sensor: The user can manually test the proper operation of the rain sensor by running a manual “all stations cycle” or by activating the system using the one touch manual method. During a manual cycle, pressing the test button on the Mini-Clik® will interrupt watering.
• Overriding the Rain Sensor: The SRR remote control device (single station operation only, not programs A, B, or C) and manual single station function on the Pro-C dial will override the rain sensor. This function provides the users the ability to operate the system even though the rain sensor has shut the system off.

Connecting an SRR or ICR Remote Control (Not Included)

The Pro-C controller is shipped with a SmartPort® wiring harness, allowing for fast and easy use of the Hunter SRR, or Long Range ICR remote controls. The SRR and ICR make it possible for contractors and end users alike to operate a system without having to walk back and forth to the controller.

To utilize the SRR or ICR Remote Control System you must install the SmartPort outlet.

1. Install a 1/2" female threaded “Tee” in the field wiring conduit approximately 12" below the Pro-C.
2. Feed the red, white, and blue wires of the harness through the base of the "Tee" and into the wiring compartment as shown in Fig. 1.
3. Screw the SmartPort harness housing into the “Tee” as shown in Fig.1.
4. Access the terminal strip area and attach the red wire to the bottom most AC screw slot, attach the white wire to the upper AC screw slot and attach the blue wire to the screw slot marked REM.

The SmartPort is now ready for remote control use. Please refer to either the SRR or ICR owner's manual for further information or contact your local Hunter distributor for ordering information.

Diagram description: Shows the SmartPort harness connection points on the controller's terminal strip: Red wire to AC (bottom), White wire to AC (upper), Blue wire to REM.

Connecting to the Hunter Irrigation Management and Monitoring System™

With the Irrigation Management and Monitoring System™ (IMMS™), automatic irrigation systems at multiple sites or multiple controllers on a single site can be programmed for functions that would typically be handled directly at each site's controller. Scheduling of days to water, run times, start times, cycle and soak operations and more can now be done from a single computer at a desk miles away from the actual installation.

In addition, scheduled operation of non-irrigation components also in use at these sites – e.g., lighting systems at athletic fields, fountains at shopping centers – as well as pumps and sensors can also be programmed and monitored from a single central location.

A key function of the IMMS is its ability to monitor changing conditions. With the aid of such options as flow sensors, rain sensors and other weather-sensing devices, the IMMS can receive reports on the current condition at every site it is linked with and then respond with the necessary adjustments should any of those conditions go beyond the limits that have been defined.

No system available today is more cost-effective than the Hunter IMMS. It's inexpensively priced and contains the most essential features needed for water management. It's able to team with any or all of the standard automatic controllers in the Hunter line-up, from the SRC to the Pro-C to the ICC. Plus, it's a system that's easy and affordable to upgrade, making it possible to accommodate an expanding network of controllers.

For more information on the IMMS, contact your local Hunter dealer.

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.

Sprinkler System Fundamentals

There are three main components that are involved with all automatic sprinkler systems that are made today. They are the controller, control valves, and the 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.

The valve controls a group of sprinklers called a watering station. These stations are laid out in a fashion according to the type of plant life that exists there, 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 terminal strip area inside of the controller. Here the wire is connected to a number that corresponds to the valve’s station number.

The controller will operate the valves in order, only one at a time. When a valve has completed its watering; it will switch to the next station that has been programmed. This process is called the watering cycle. The information pertaining to the watering times of the individual stations and the duration of them is called a program.

Diagram description: A Pro-C controller is shown connected to multiple sprinkler stations (Station 1 through Station 6) via valves. The diagram illustrates a typical lawn layout with different types of sprinklers and indicates which valve activates which station and its function (e.g., Valve 1 activates Station 1 for rotors watering the front lawn).

Programming Fundamentals

For the controller and its selected program to operate automatically, there are three components that must exist: When to water (or Watering Start Times), how long to water (or Station Run Times), what day of the week to water (or Days to Water).

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 on separate programs.

Going back to our previous example, 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 activate 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.

As shown in the above example, only one program start time was required to run the three different stations. The controller automatically moves to the next station without the need for additional start times.

We realize that many consumers will have variations in their plant watering needs, so at Hunter we equipped the Pro-C with three different programs A, B, and C. These programs are completely independent of each other and give you the ability to have three coexisting timers in one controller.

Diagram description: Three diagrams illustrate a clock face for Station 1, Station 2, and Station 3. Each shows sprinklers starting at a specific time, watering for a duration, and then turning off. The overall program start and end times are also indicated.

Creating a Watering Schedule

For most consumers, it is much easier to plan your specific watering schedule onto paper before actually programming the information into the controller. It's also handy to have a written record of your programming information for easy reference.

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. Since there are so many different variables that can determine your individual watering schedule, it is impossible to give an exact schedule to follow. However, we have included some guidelines to help you get started.

How to Fill Out the Watering Schedule

Be sure to use a pencil when filling out this form. By using the included example and the information below, you should have all the information you need to construct your personal water schedule.

• 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.
• Program Start Times: Indicate the time of day that the program will begin. Each program can have 1-4 start times. However, one start time can run an entire program.
• Station Run Time: Indicate the run time (1 minute – 6 hours) for each station. Write “OFF” for any station that you do not want to operate in the program.

Keep this schedule in a safe place for quick reference later, rather than scrolling through program information on the controller.

Watering Schedule Form

Programming the Controller

Two key features of the Pro-C that make programming a snap are its clear, easy-to-read LCD display and its easy-to-use dial design.

The Pro-C display shows time and day when the controller is idle. The display changes when the dial is rotated to indicate the specific programming information to enter. When programming, the flashing portion of the display can be changed by pressing the + or - buttons. To change something that is not flashing, press → or ← until desired field is flashing.

The Pro-C controller offers maximum scheduling flexibility including three programs, each with up to 4 daily start times, permitting plants with different watering requirements to be separated on different day schedules. Multiple start times permit morning, afternoon and evening watering, perfect for the establishment of new lawns and thirsty annual flowers. A built in 365-day calendar clock accommodates odd/even watering restrictions without requiring monthly reprogramming. Or, just simply designate the days of the week you want to water or use the convenient day interval watering.

Setting the Current Date and Time

1. Turn the dial to the SET CURRENT DATE/TIME position.
2. The current year will be flashing in the display. Use the + and - buttons to change the year. After setting the correct year, push the → button to proceed to setting the month.
3. The month and day will be in the display. The month will be flashing. Use the + and - buttons to change the month. Press the → button to proceed to setting the day.
4. The day will be flashing: Use the + and - buttons to change the day of the month (The day of the week is automatically selected.) Press the → button to proceed to setting the time.
5. The time will be displayed: Use the + and - buttons to select AM, PM, or 24 hr. Press the → button to move to hours. Hours will be flashing. Use the + and - buttons to change the hour shown on the display. Press the → button to move onto the minutes. Minutes will be flashing. Use the + and - buttons to change the minutes shown in the display. The date, day, and time have now been set.

Diagram description: Shows the controller display sequentially changing to display the Year, Month/Day, and Time settings, with flashing digits indicating the value being adjusted.

Setting Watering Start Times

1. Turn the dial to the SET WATERING START TIMES position.
2. The factory preset is set on program A. If necessary you can select program B or C by pressing the PRG button.
3. Use the + and - buttons to change the start time. (Advances in 15-minute increments.) One start time will activate all stations sequentially in that program. This eliminates the need to enter a start time for each station. Multiple start times in a program can be used for separate morning, afternoon, or evening watering cycles.
4. Press the → button to add an additional start time, or the PRG button for the next program.

Eliminating a Program Start Time

With the dial set to the SET WATERING START TIMES position, push the + and - buttons until you reach 12:00 AM (Midnight). From this position push the → button once to reach the OFF position.

Setting Station Run Times (Length of Watering for Each Area)

1. Turn the dial to the SET STATION RUN TIMES position.
2. The display will show the last program selected (A, B, or C), the station number selected, and the run time for that station will be flashing. You can switch to another program by pressing the PRG button.
3. Use the + and - buttons to change the station run time on the display.
4. Press the → button to advance to the next station.
5. Repeat steps 3 and 4 for each station.
6. You may set station run times from 1 minute to 6 hours.
7. You can move between programs while staying on the same station. However, it is recommended that one program is completed before going on to the next program. Jumping between programs can be confusing and may result in program errors.

Diagram description: Shows the controller dial set to 'SET STATION RUN TIMES' and the display showing the current program (A), station number (1), and run time (e.g., 1:20).

Setting Days to Water

1. Turn the dial to the SET DAYS TO WATER position.
2. The display will show the last program selected (A, B, or C). You can switch to another program by pressing the PRG button.
3. The controller displays currently programmed active day schedule information. This dial position provides four different water day options: you can choose to water on specific days of the week, or you can choose interval watering, or choose to water on odd days or even days. Each program can only operate using one type of water day option.

Selecting Specific Days of the Week to Water

1. Press the → button to activate a particular day of the week to water (the display always starts with Monday). Press the ← button to cancel watering for that day. After pressing a button the display automatically advances to the next day. A ● indicates a water day. An empty circle indicates a no water day.
2. Repeat step 1 until desired days have been selected.

After programming, set dial to RUN to enable automatic execution of all selected programs and start times.

Selecting Interval Watering

This feature is convenient if you want to have a more consistent watering schedule without having to worry about the day of the week or the date. The interval you select is the amount of days between watering. The days remaining indicates how many days until the next watering. For example if you select an interval of 2 with 1 day remaining, watering will begin tomorrow at the scheduled time.

1. Press the → button with the cursor on Sunday. Interval and Days Left will appear in the display.
2. Interval is flashing press the → button. The display will increment the interval.
3. Press →, the number of days left will be flashing. Use the + and - buttons to select the number of days left until the next watering.

After programming, set dial to RUN to enable automatic execution of all selected programs and start times.

Diagram description: Shows the controller display for Interval and Days Left settings, with flashing values indicating the current setting.

Selecting Odd or Even Days to Water

This feature uses a numbered day of the month for watering instead of specific days of the week (odd days 1st, 3rd, 5th, etc.; even days 2nd, 4th, 6th, etc.).

1. Using the instructions for Interval Watering, set the interval to one.
2. Press the → button until the cursor is on either EVEN or ODD in the display. Select whichever you choose as No Water Days by pressing the ← button. If you select ODD as No Water Days then the controller will only water on even days of the month. Conversely, if you select EVEN as No Water Days then the controller will only water on odd days of the month. You can also set particular days of the week as no water days using this feature (see Advanced Features on page 27).

After programming, set dial to RUN to enable automatic execution of all selected programs and start times.

Weather Sensor Bypass

With this built-in feature, there is no need for an additional manual bypass switch when using rain sensors (the Pro-C works with the Hunter Mini-Clik®, plus some other rain, wind, and freeze sensors on the market today). If the system is preventing system operation (or no sensor is installed and the switch is in the ACTIVE position), SENSOR OFF will be displayed. Simply move the switch to BYPASS and the weather sensor will be bypassed. This allows you to use the system.

Diagram description: Shows the Rain Sensor Bypass switch on the controller, with options for ACTIVE and BYPASS.

Run

After programming is complete, turn the dial to RUN to enable automatic execution of all selected programs and start times.

System Off

Valves currently watering will be shut off after the dial is turned to the SYSTEM OFF position for two seconds. All active programs are discontinued and watering is stopped. To return controller to normal automatic operation, simply return dial to RUN position.

Diagram description: Shows the controller dial in the RUN position and the SYSTEM OFF position.

Manually Run a Single Station

1. Turn the dial to the MANUAL-SINGLE STATION position.
2. Station run time will flash in the display. Use the → button to move to the desired station. You may then use the + and - buttons to select the amount of time for a station to water.
3. Turn the dial to the RUN position to run the station (only the designated station will water, then controller will return to automatic mode with no change in the previously set program).

Diagram description: Shows the controller dial set to MANUAL-SINGLE STATION and the display showing a station number and run time.

Manually Run All Stations

1. Turn the dial to MANUAL-ALL STATIONS.
2. You can select program A, B, or C by pressing the PRG button.
3. Press the → button until desired starting station is displayed.
4. Station run time will flash in the display. Use the + and - buttons to select the amount of run time for the station to water if different from the run time displayed.
5. Use the → button to move to the next station.
6. Repeat steps 3 and 4 to customize each station if desired.
7. Press the → button until desired starting station is displayed.
8. Return the dial to RUN (custom program will water the entire program beginning with the station number last left in the display, then controller will return to automatic mode with no change in the previously set program).

Diagram description: Shows the controller dial set to MANUAL-ALL STATIONS and the display showing a station number and run time.

One Touch Manual Start and Advance

You can also activate all stations to water without using the dial.

1. Hold down the → button for 2 seconds.
2. This feature automatically defaults to program A. You can select program B, or C by pressing the PRG button.
3. The station number will be flashing. Press the → or ← button to scroll through the stations and use the + and - buttons to adjust the station run times. (If no buttons are pressed during step 2 or 3, the controller will automatically begin program A.)
4. Press the → button to scroll to the station you wish to begin with. After a 2 second pause, the program will begin.

This feature is great for a quick cycle when extra watering is needed or if you would like to scroll through the stations to inspect your system.

Diagram description: Shows the controller display during manual start and advance operations, indicating station number and run time.

Seasonal Adjustment

Seasonal Adjust is used to make global run time changes without re-programming the entire controller. This feature is perfect for making small changes that are necessary as the weather changes without reprogramming the entire controller. For instance, hotter times of the year may require a bit more water. Seasonal adjust can be increased so that the stations will run longer than the programmed time. Conversely, as Fall approaches, the seasonal adjust can be reduced to allow for short watering durations.

To use the seasonal adjust, simply press the ▲ or ▼ seasonal adjust buttons to set the percentage desired. Each bar on the graph can be adjusted from 10% to 150% of original program. The season adjust can be changed at any time regardless of the programming dial position. To view the new adjusted run time, simply turn the rotary dial to the Set Run Times position, the displayed run time will be updated accordingly as the seasonal adjustment is made.

Diagram description: Shows the Seasonal Adjust buttons (+ and -) and the Seasonal Adjust Display on the controller.

Advanced Features

There are three advanced features available to customize the Pro-C to more complex watering requirements. One of these features is “hidden” to make accidentally programming them nearly impossible.

1) Set Pump/Master Valve Operation

The default is for all stations to have the master valve/pump start circuit ON. The master valve/pump start can be set ON or OFF by station, regardless of which program the station is assigned. This feature may be utilized on systems where it is desirable for a booster pump not to operate with certain zones.

To program pump operation:

1. Turn the dial to SET PUMP OPERATION position.
2. Press the + or - buttons to toggle the master valve/pump start ON or OFF for the specific station.
3. Press the → button to advance to the next station.
4. Repeat steps 2 and 3 for all necessary stations.

Diagram description: Shows the controller dial set to SET PUMP OPERATION and the display showing a station number and its pump/master valve status (ON/OFF).

2) Programmable Rain Off

This feature permits the user to stop all programmed waterings for a designated period from 1 to 7 days. At the end of the programmable rain off period, the controller will resume normal automatic operation.

1. Turn the dial to the SYSTEM OFF position.
2. Press the → button and a 1 will be displayed and the DAYS LEFT icon will illuminate. The 1 will be blinking at this point.
3. Press → as many times as needed to set the number of days off desired (up to 7).
4. To validate this setting (and to make sure the controller comes back on after the period is over), turn the dial back to the RUN position at which time, OFF, a number and the DAYS icon all remain on.
5. Leave the dial in the RUN position. The days off remaining will decrease at midnight of each day. When it goes to zero, the display will show the normal time of day and normal irrigation will resume at the next scheduled start time.

3) Setting Event Day(s) Off

Programming in a No Water Day(s) is useful to inhibit watering on mowing days, etc. For instance, if you always mow the lawn on Saturdays you would designate Saturday as a No Water Day so you are not mowing wet grass.

1. Turn the dial to the DAYS TO WATER position.
2. Enter an interval watering schdule as described on page 24.
3. With the days left flashing, press the → button to display the days of the week. MON will be flashing.
4. Use the → button until the cursor is at the day of the week you wish to set as a No Water Day.
5. Press the ← button to set this day as a no water day. The ● will illuminate over this day.
6. Repeat steps 4 and 5 until all desired event day(s) are off.

Diagram description: Shows the controller dial set to DAYS TO WATER, and the display showing the days of the week (MON TUE WED THU FRI SAT SUN) with a cursor and a filled circle indicating a selected 'no water' day.

1) Programmable Delay Between Stations

This feature allows the user to insert a delay between when one station turns off and the next station turns on. This is very helpful on systems with slow closing valves or on pump systems that are operating near maximum flow or have slow well recovery.

1. Start with the dial in the RUN position.
2. Press and hold the → button down while turning the dial to the SET STATION RUN TIMES position.
3. Release the → button. At this point the display will show a delay time for all stations in seconds, which will be blinking. The DELAY icon shall also be lit at this time.
4. Press the + and - buttons to increase or decrease the delay time between 0 and 59 seconds in 1 second increments and then in one minute increments up to four hours. Hr will be displayed when the delay changes from seconds to minutes and hours.
5. Return the dial to the RUN position.

Diagram description: Shows the controller dial in RUN and SET STATION RUN TIMES positions. The display shows SEC: 0 with the DELAY icon lit, and later shows the delay time in minutes/hours.

2) Test Program

The Pro-C allows the user a simplified method for running a test program. This feature operates each station in numerical sequence, from the lowest to the highest. You can start with any station. This is a great feature to check the operation of your irrigation system.

1. Press and hold the PRG button. The station number will be flashing.
2. Press the → or ← button to scroll to the station you would like the test program to start with. Use the + and - button to set a run time of up to 15 minutes. The run time needs to be entered only once.
3. After a 2 second pause, the test program will begin.

3) Hunter Quick Check™

Irrigation professionals are continuously looking for ways to more efficiently and effectively diagnose programs in the field. Instead of having to physically check each field wiring circuit for potential problems, the user can run the Hunter Quick Check™ circuit test procedure. This circuit diagnostic procedure is very beneficial because of its ability to aid in quickly identifying “shorts” commonly caused by faulty solenoids or when a bare common wire touches a bare station control wire.

To initiate the Hunter Quick Check test procedure; Press the +, -, and PRG buttons simultaneously. In the standby mode, the LCD will display all segments (helpful when troubleshooting display problems). Press the → button to begin the Quick Check test procedure. Within seconds, the system searches all stations in an effort to detect a high current path through the station terminals. When a field wiring short is detected, an ERR symbol preceded by the station number will momentarily flash on the controller LCD display. After the Hunter Quick Check completes running this circuit diagnostic procedure, the controller returns to the automatic watering mode.

4) Clearing Controller's Memory/Resetting Controller

If you feel that you have misprogrammed the controller, there is a process that will reset the memory to factory defaults and erase all programs and data that have been entered into the controller. Press the +, -, and the PRG buttons simultaneously and hold them down, while they are being held down, press and release the RESET button on the back of the front panel. Then release the +, -, and the PRG buttons. The display should now show 12:00 am. All the memory has been cleared and the controller may now be reprogrammed.
