MOUNTING THE CONTROLLER TO A WALL All necessary hardware is included for most installations. 1. Use the hole at the top of the controller as a reference and secure a 1" (25 mm) screw into the wall. Note: Install screw anchors if attaching to drywall or masonry wall. 2. Align controller with the screw and slide the keyhole on top of the controller over the screw. 3. Secure controller in place by installing screws in the holes.
CONNECTING AC POWER 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. ① GND ① ② ③ (Green) To be performed by a licensed electrician only. Always use UL listed ½” (13 mm) conduit with male adapter when installing AC wiring. Pro-C/PCC controllers are intended to be supplied AC power with a 15A rated overcurrent protected device.
INSTALLING STATION MODULES Installing PCM 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) or a single 9-station (PCM-900) to expand the controller’s station capability to 16 stations. Additional modules are sold separately. 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.
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. 4 3. Route valve wires through the conduit and attach conduit to one of the openings on the bottom of the cabinet. 3 4.
CONNECTING THE BATTERY (OPTIONAL) NOTE: Warning: Risk of fire, explosion, and electric shock. Replace battery with CR 2032 type only. Use of a different battery has potential risk for fire, explosion, and electric shock. See owner’s manual for instructions. Connect a 9-volt alkaline battery (not included) to the battery terminals and place in the battery compartment in the front panel. The battery allows the user to program the controller without AC power. Watering will not occur without AC power.
Connecting a Master Valve (optional) Connect either wire from Master Valve to the P/MV terminal. Connect remaining wire to the “COM” (Common) terminal.
CONNECTING A PUMP START RELAY (OPTIONAL) 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 terminal slot. Relay holding current draw must not exceed 0.28 amps (24 VAC). Do not connect the controller directly to the pump— damage to controller will result. For more information on the installation of a PSR, please visit the support page:http://www.hunterindustries.
CONNECTING A HUNTER “CLIK” WEATHER SENSOR (NOT INCLUDED) A Hunter weather sensor or other micro-switch type weather sensors can be connected to the Pro-C. The purpose of this sensor is to stop automatic watering when weather conditions dictate. When the weather sensor has deactivated automatic watering, “OFF” will appear on the display. 1. Remove the metal jumper plate that is attached across the two SEN terminals inside the controller. 2.
CONNECTING A HUNTER “CLIK” WEATHER SENSOR (CONTINUED) 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 (eg. Mini-Clik ®) will interrupt watering.
CONNECTING A HUNTER REMOTE (NOT INCLUDED) The Pro-C is compatible with Hunter remote controls. The SmartPort wiring harness (included with all Hunter remotes) allows for fast and easy use of Hunter controls. Hunter remotes make it possible for you to operate the system without having to walk back and forth to the controller. 4. A ttach the red wire to the screw slot marked AC1, attach the white wire to the screw slot marked AC2, attach the blue wire to the screw slot marked REM.
CONNECTING A HUNTER REMOTE (CONTINUED) REM (Blue) AC2 (White) AC1 (Red) 12” / 30cm NOTE: Any extension of the wiring on the SmartPort® may result in an error message in the controller display and possible malfunction of the remote unit due to radio interference. In some situations, lengthening of the harness may work fine, in others it may not work at all (it is site - specific).
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.
CONNECTING A HUNTER SOLAR SYNC® ET SENSOR 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.
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.
CONNECTING A HUNTER SOLAR SYNC® ET SENSOR + The Water Adjustment is a 1 to 10 scale that allows for easy Water Adjustment Uninstalling a Solar Sync® Sensor 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.
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 master valve/pump start can be set ON or OFF by station, regardless of which program the station is assigned. To program pump operation: 1. Turn the dial to the PUMP 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.
HIDDEN FEATURES Program Customization Programmable Delay Between Stations The Pro-C is factory - configured with 3 independent programs (A, B, C with four start times each) for different plant type requirements. The Pro-C can be customized to display only the required programs. You can hide those programs that are not required to ease programming. This feature allows the user to insert a delay between when one station turns off and the next station turns on.
HIDDEN FEATURES (CONTINUED) Programmable Sensor Override The Pro-C allows the user to program the controller so that the sensor disables watering on only desired stations. For example, patio gardens that have pots under overhangs and roofs may not receive water when it rains and will continue to need to be watered during periods of rain. To program sensor override: A station that is running in the sensor override mode will display the word “SENSOR” and flash the icon. 1.
HIDDEN FEATURES (CONTINUED) Total Run Time Calculator Easy Retrieve™ Program Memory The Pro-C keeps a running total of each program’s station run times. This feature provides a quick way to determine how long each program will water. The Pro-C is capable of saving the preferred watering program into memory for retrieval at a later time. This feature allows for a quick way of resetting the controller to the original programmed watering schedule. 1.
HIDDEN FEATURES (CONTINUED) Solar Sync Delay for Pro-C To change the existing Delay days setting: The delay feature is accessible only after the installation of the Solar Sync. The Solar Sync Delay feature allows the user to postpone seasonal adjustment changes from being made by Solar Sync for up to 99 days. 1. Open the Solar Sync Delay menu by pressing the + button and rotating the dial to Solar Sync Settings and release the + button.
HIDDEN FEATURES (CONTINUED) 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.
HIDDEN FEATURES (CONTINUED) Accessing the Soak Menu: Once the desired Cycle times for each station have been programmed, the Cycle time can be accessed by pressing the PRG button. The station will remain the same as was previously displayed under the Cycle time (i.e. if station 2 is displayed in the Cycle menu then Station 2 will be displayed upon pressing the PRG button). Once the desired station is displayed, the user can use the + or - button to increase or decrease the Soak time.
HIDDEN FEATURES (CONTINUED) Hunter Quick Check™ This circuit diagnostic procedure can quickly identify “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: 1. Press the +, -, ← and→ buttons simultaneously. In the standby mode, the LCD will display all segments (helpful when troubleshooting display problems). 2. P ress the + button to begin the Quick Check test procedure.
CLIK DELAY INSTRUCTIONS Clik Delay Feature This feature allows the user to delay programmed waterings for a designated period (from 1-7 days) AFTER a Clik Event ends. At the end of Programmed Clik Delay period, the controller will resume normal automatic irrigation. SENSOR DAYS LEFT 1. Turn the dial to the RUN Position 2. Press and hold the “+” button for 3 seconds, then turn the dial to the OFF position 3. Release the “+” button. The display will show the program- mable Clik Delay.
TROUBLESHOOTING GUIDE 42 Problem Cause Solution The controller repeats itself or continuously waters, even when it should not be on (cycling repeatedly). Too many start times (Programming Error). Only one start time per active program is required. Refer to “Setting Program Start Times” on page 25. There is no display. Check AC power wiring. Correct any errors. The display reads “SP ERR”. Electrical noise is entering the system. Check the SmartPort ® wiring harness.
TROUBLESHOOTING GUIDE (CONTINUED) Problem Cause Solution The display reads “SENSOR OFF”. The rain sensor is interrupting irrigation or the sensor jumper is not installed. Slide the Rain Sensor switch on front panel to the BYPASS position to bypass rain sensor circuit, or install the sensor jumper. Rain sensor will not shut off system.
