INSTALLING STATION MODULES

The Pro-C controller is supplied with a factory-installed base module for up to 4 stations. Additional modules may be added in increments of 3 stations (PCM-300), 9 stations (PCM-900), or

16 stations (PCM-1600). In total, a conventionally wired system can be expanded up to 23 stations. Additional modules are sold separately.

The Pro-C is also compatible with the EZ Decoder System

(EZDS) for hybrid conventional and two-wire operations. Add a Pro-C Decoder Module (PC-DM) to enable control for up to

32 total stations. This system uses the same EZ-1 decoders used with ICC2 and HCC controllers. For more installation and programming details, please refer to the PC-DM Installation

Guide.

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 once or at the same time by simply pushing the “ Power Lock ” slide.

1. Slide the “ Power Lock ” into the “ Power Off ” (unlocked) position. Insert the PCM or PC-DM modules into the appropriate sequential position in the controller cabinet.

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 on the back of the facepack or cycle power to the controller.

NOTE: To expand your controller to 16 or

23 stations with a PCM-900 or PCM-1600, respectively, install one PCM-300 in the first expansion slot (stations 5–7). Then install the PCM-900 or PCM-1600 in the upper two expansion slots. These modules will not fit or operate in any other station output slot.

CONNECTING STATION WIRES

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. Route valve wires through the conduit and attach conduit to one of the openings on the bottom of the cabinet.

4. Strip ½" (13 mm) of insulation from ends of all wires.

Secure the valve common wire to “ COM ” (Common) terminal.

Attach all individual valve control wires to the appropriate station terminals.

NOTE: The common terminal screw has moved from the base module and is now below the sensor terminals. Do not connect the incoming common wires to the P/MV terminal.

Testing the Weather Sensor

The Pro-C provides simplified testing of a rain sensor when the sensor is wired into the sensor circuit. You can manually test proper operation of the rain sensor by using the One -

Touch Manual Start (see page 30). During the Manual cycle, pressing the test button on the “Clik-type” sensor

(e.g., Mini-Clik ® ) will interrupt watering.

NOTE: The Manual single-station function ignores any attached sensor and will allow watering to occur.

Manually Bypassing the Weather Sensor

If the rain sensor is interrupting irrigation, you can bypass it by using the bypass switch on the front of the controller.

Slide the switch to the Bypass position to disable the rain sensor from the system to allow for controller operation. You can also bypass the weather sensor for manual operation by using the Manual function. The Bypass switch does not affect the

Seasonal Adjust update when using the Solar Sync sensor.

In some situations, lengthening of the harness may work fine, in others it may not work at all (it is site specific). In either case, extending the wiring harness should be done using shielded cable to minimize the possible effects of electrical noise. For easiest installation, order the Hunter

SmartPort shielded cable wiring harness.

(P/N ROAM-SCWH) with a full 25’ (7.6 m) of shielded cable.

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 watering based upon 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.

The controller will automatically increase or decrease watering run times based on changes in weather. 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.

For installation and programming instructions of your Hunter

Solar Sync, please refer to the Solar Sync owner’s manual or visit the Solar Sync support section on our website: https://hunter.direct/solarsynchelp

ET SENSOR

20

This controller is compatible with the Solar Sync and Wireless

Solar Sync systems. Solar Sync is a sensor system that will automatically adjust the controller’s watering schedule (based on changes in local climate condition) by using the Seasonal

Adjust function. The Solar Sync uses a solar and temperature sensor to determine evapotranspiration (ET), or the rate at which plants and turf use water, and also includes Hunter

Rain-Clik and Freeze-Clik technology that will shut down irrigation when it rains and/or during freezing conditions.

NOTE: Solar Sync will apply a default seasonal adjust value of 100% until the first full day (24-hour period) of weather measurements have been received from the sensor.

NOTE: Enabling the Sensor Bypass switch has no effect on the seasonal adjust updates from the

Solar Sync sensor. It will, however, bypass the Rain-

Clik and Freeze-Clik functionality of the sensor.

Installing Solar Sync Sensor

Connect the Green and Black wire from the Solar Sync Sensor to the

“SEN” wiring terminals on the controller. It does not matter which wire connects to which terminal. Turn the dial to the “Solar

Sync Settings” position. The display will initially show dashed lines and then will show the default Region setting (3) on the left and the default Water Adjustment setting (5) on the right.

Adjust the Region as needed by using the and buttons

(refer to page 21 for explanation of Solar Sync Region setting).

Use the button to advance to the right to adjust the Water

Adjust setting as needed (see page 22 for explanation of

Water Adjust setting).

Installing the Wireless Solar Sync

Connect the Green and Black wire from the Wireless Solar

Sync Receiver to the “SEN” wiring terminals on the controller.

It does not matter which wire connects to which terminal.

Turn the dial to the “Solar Sync Settings” position. The display will initially show dashed lines and then will show the default Region setting (3) on the left and the default Water

Adjustment setting (5) on the right. Adjust the region as needed by using the and buttons (refer to page 13 for explanation of Solar Sync Region setting). Use the button to advance to the right to adjust the Water Adjust setting as needed (see page 14 for explanation of Water Adjust setting).

Solar Sync Settings

Once the Solar Sync sensor is connected to the controller, two numbers will appear in the display when the dial is turned to the Solar

Sync Settings position. The number on the left of the screen is the Region setting, and the number on the right on the screen is the

Water Adjustment setting (as shown above).

CONNECTING A HUNTER SOLAR SYNC ET SENSOR

Region

For accurate Solar Sync measurements, the controller needs to be programmed for the average peak season ET for your region.

Use the table below to determine your region.

The table will assist you in identifying the type of region you live in. There are four basic ET regions, each with descriptions of the region, along with typical ET and temperature characteristics. It is recommended that, if possible, the region be chosen based upon average July ET or peak summer ET (inches/mm per day).

Use the following table for choosing your region (reference below).

You can use methods A , B, or C to help you choose which region is best for your area:

A: Based upon the ET of your region using the average July ET or peak summer ET (inches/mm per day). This is the preferred option when selecting your region.

B: Based upon the temperature for your region using the average

July or the driest month high temperature (not the highest temperature for July).

C: Based upon the general description of your region.

Water Adjustment

+ adjustment of the Seasonal Adjust value from the Solar Sync ET

Sensor. Upon installation of the Solar Sync ET Sensor, keep the

Water Adjustment setting at the default value of 5. However, after installation, if you find that the seasonal adjust value is lower or higher than expected, the Water Adjustment value can be modified to the Seasonal Adjust output value. See Calibration/Setup on page

15 for explanation of how to use Water Adjustment scale to fine-tune seasonal adjust output value.

NOTE: If an individual zone is “wetter” or

“drier” than the rest of the system, simply increase or decrease the amount of run time on the controller.

Uninstalling a Solar Sync Sensor

If a Solar Sync sensor has been installed, then the seasonal adjust value used by the controller will be calculated from the weather data supplied by the Solar Sync sensor.If the Solar Sync sensor is no longer used with the controller, it must be uninstalled. If the Solar

Sync sensor is not uninstalled, the controller will not allow the seasonal adjust value to be manually changed. For example, if the seasonal adjust value shown on the controller was 50 percent when the Solar Sync sensor was removed, it will remain 50 percent until the Solar Sync sensor is uninstalled.

To uninstall the Solar Sync sensor, simply disconnect the green and black wires from the controller terminal and then turn the dial to the “Solar Sync Settings” position. The display should show dashes, indicating that the controller no longer recognizes the Solar Sync sensor for calculation of seasonal adjustment. Now the seasonal adjust value can be changed manually by turning the knob to the

“Seasonal Adjust” position and using the + or - button to adjust the value.

CONNECTING A HUNTER SOLAR SYNC ET SENSOR

Calibration/Setup

After Solar Sync has been installed and programmed, allow the system to run for a few days at the initial setting. Because of the variety in site conditions (including sensor location, amount of direct sunlight available to the sensor, reflective heat from surrounding structures, etc), the initial setting may require adjustment to arrive at the desired performance. The calibration of the Solar Sync to a particular site can easily be accomplished by adjusting the Region and/or Water Adjustment settings. The instructions below outline this process:

1. Install Solar Sync sensor

2. Program Region and allow system to operate at initial setting for a minimum of 3 days

3. Observe the Seasonal Adjust on the controller. If the Seasonal Adjust amount appears to be lower or higher than expected for that time of year, the Solar Sync settings need to be adjusted. a. Seasonal Adjust too low: Turn the dial to the Solar Sync settings position. Increase the value on the Water Adjustment scale (10 is max).

Once the setting is changed, the controller will immediately be updated with the new Seasonal Adjust percentage. Increase the Water

Adjustment setting until the desired Seasonal Adjust percentage is shown. If you max out the Water Adjustment scale at 10 and still require more Seasonal Adjust, move down to the next lower Region (from Region 4 to 3, for example).

b. Seasonal Adjust too high: Turn the dial to the Solar Sync settings position. Decrease the value on the Water Adjustment scale (default setting is 5). Once the setting is changed, the controller will immediately be updated with the new Seasonal Adjust percentage. Decrease the Water Adjustment setting until the desired Seasonal Adjust percentage is shown.

If you minimize the Water Adjustment scale down to 1 and still require a reduction in Seasonal Adjust, move up the next Region (from Region 2 to 3, for example).

Station Run Times: It is important to understand that Solar Sync provides a global seasonal adjustment to the controller. This means that all station run times will be modified by the seasonal adjust percentage shown. When programming the controller, the run times should be entered that represent peak season watering schedules. If the Solar Sync is adjusting to the appropriate seasonal adjust value but the run time for a particular station appears to be too long/short, adjust the station run time in the controller program.

3. Press the + button. The display will now show two numbers: the interval, and the days remaining in the interval.

4. The number of days between waterings, or the interval, will be flashing. Use the + and - buttons to select the number of days desired between waterings.

5. Press the → button. The days remaining in the interval are now flashing. Use the + and - buttons to select the number of days until the next desired watering. One day remaining means it will water the next day.

NOTE: If any days are selected as nonwater days at the bottom of the display, the Interval Day watering will exclude those days. For example, if the Interval

Days are set at 5 and Monday is a nonwater day, the controller will water every

5th day, but never on a Monday. If the interval water day falls on a Monday and

Monday is a non-water day, the program would not water for 5 more days resulting in no irrigation for 10 days total.

OPTIONS FOR RUNNING YOUR IRRIGATION SYSTEM

Run

After programming is complete, turn the dial to the RUN position 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 the RUN position.

Manually Run a Single Station

1. Turn the dial to the MANUAL 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).

NOTE : The Manual single station function ignores any attached sensor and will allow watering to occur.

Seasonal Adjustment

Seasonal Adjust is used to make global run time changes without reprogramming the entire controller.

This feature is perfect for making small changes that are necessary as the weather changes. 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.

1. Turn the dial to the SEASONAL ADJUST position.

2. Press the + or - buttons to set the percentage desired from 5 percent to 300 percent.

To view the new adjusted run time, turn the dial to set run time’s position. The displayed run times will be updated accordingly as the seasonal adjustment is made.

NOTE: The controller should always be initially programmed in the 100% position.

Cycle and Soak

The Cycle and Soak feature allows you to split a station’s run time into more usable, shorter watering durations. This feature is useful when applying water to slopes and tight soils because it automatically applies water more slowly, helping to prevent runoff from occurring. You should enter the Cycle time as a fraction of the station’s watering time, and the Soak time as the minimum number of minutes required before watering can occur again for the next Cycle. The total number of cycles is determined by taking the total programmed station run time and dividing it by the Cycle time.

Accessing the Cycle and Soak Menu:

The Cycle and Soak feature is accessed by placing the dial in the RUN position, pressing and holding the + button for 3 seconds; while holding the + button rotate the dial to the RUN

TIME dial position, then release the button.

Setting the Cycle Time:

Initially Station 1 will be displayed. To access other stations, press the ← or → button.

Once the desired station is displayed, use the + or - button to increase or decrease the Cycle time. The user can set the time from 1 minute to 4 hours in 1-minute increments or to OFF if no

Cycle is desired.

NOTE: Before 1 hour, only minutes are displayed (e.g., 36). At 1 hour or above, the display will change to include the hour digit (e.g., 1:13 and 4:00).

If a station’s Run Time is less than or equal to the Cycle time, then no Cycle will be applied.

The user can set the Soak time from 1 minute to 4 hours in 1-minute increments.

NOTE: Before 1 hour, only minutes are displayed (e.g., 36). At 1 hour or above, the display will change to include the hour digit (e.g., 1:13 and 4:00).

NOTE: The Soak menu cannot be accessed without a programmed Cycle time.

Setting the Soak Time:

To access the other stations, press the ← or → button.

NOTE: When changing the stations, if a station without a Cycle time is encountered, the screen will revert back to the Cycle time. Move to the next station with a Cycle Time and press the PRG button to return.

Example of Soak screen with only minutes

Example of Soak screen with hours included

Cycle and Soak Situations:

Station 1 requires 20 minutes of watering, but after 5 minutes, runoff occurs. However, after 10 minutes all the water is absorbed. The solution would be to program 20 minutes for the station run time, 5 minutes for the Cycle time, and 10 minutes for the Soak time.

The soak time is a minimum amount. The soak time may be longer amount depending on the remaining run times.
