Installation Instructions

Connecting Station Wires

Each ICC2 Controller comes with a factory-installed base module for up to 8 stations (ICM-800). Additional modules may be added in increments of four (ICM-400), eight (ICM-800), or one 22-station expansion module (ICM-2200). Each station module has its own common terminal, which runs in conjunction with the corresponding station terminals within the module. Each station output is rated for 0.56 A maximum, which can safely operate up to two Hunter solenoids simultaneously.

1. Route station/valve wires between the control valve and the controller.
2. At the valve(s), attach the common wire to either solenoid wire for each individual valve. This is most commonly a white-colored wire. Attach a separate control wire to the second remaining solenoid wire of each valve. All wire splice connections should be made using waterproof connectors.
3. Route all common and valve control wires through an incoming conduit to the controller. The conduit can attach to any of the knockout openings at the bottom of the cabinet from 1/2" (13 mm) up to 2" (50 mm) diameter.
4. Strip 1/2" (13 mm) of insulation from the ends of all wires. Secure the valve common wires to corresponding COM terminals. Attach all individual valve control wires to the appropriate station terminals.

Connecting a Master Valve (Optional)

Complete this section only if you have a Master Valve installed.

The ICC2 Controller has one Pump/Master Valve (P/MV) output, which is capable of activating either a normally closed Master Valve or 24 VAC Pump Start Relay. A Master Valve is typically installed at the supply point of the main line and opens only when the automatic system is activated. The purpose of a Master Valve is to shut off the water to the irrigation system when none of the station valves are operating. It's also beneficial for shutting off a system when a zone or mainline develops a leak or break. The P/MV output is rated for up to 0.56 A.

1. Route the Master Valve wire pair into and out of the cabinet similarly to the station wires.
2. The P/MV output is located on the power output module in the upper left corner of the ICC2 Controller.
3. Connect either wire from the Master Valve to the P/MV terminal, and connect the remaining wire to the common COM terminal.
4. The Master Valve can be set to activate with any station. By default, it activates with all stations, but it can be programmed to enable or disable for individual stations.

Connecting a Pump Start Relay (Optional)

Complete this section only if you have a Pump Start Relay installed.

The ICC2 Controller features one Pump/Master Valve (P/MV) output for activating either a normally closed Master Valve or 24 VAC Pump Start Relay. A Pump Start Relay is an electrical device that allows the controller to operate a pump when supplying water to the system. Pumps must always be connected through a Pump Start Relay to avoid damaging the controller. The P/MV output supports up to 0.56 A.

1. Route the Pump Start Relay wire pair into and out of the cabinet similarly to the station wires.
2. The P/MV output is located on the power output module in the upper left corner of the controller.
3. Hunter Pump Start Relays come with two yellow 24 VAC flying leads: one that connects to the common COM terminal and one to the P/MV terminal.
4. Mount the controller at least 15' (4.5m) from the Pump Start Relay to minimize electromagnetic noise. Although issues are rare, the 24 VAC wires can sometimes transmit noise back to the controller, and maintaining this distance helps prevent interference.
5. The Pump Start Relay can be set to activate with any station. By default, it activates with all stations, but it can be programmed to enable or disable for individual stations.

Connecting a Hunter Clik Sensor

A Hunter weather sensor or any normally closed, micro-switch-type sensor can be connected to the ICC2 Controller. The purpose of this sensor is to stop automatic watering when weather conditions dictate. The controller has one weather sensor input available and is compatible with Hunter's full line of Clik sensors, including:

• Flow-Clik® Sensor
• Freeze-Clik® Sensor
• Mini-Clik® Sensor (wired and wireless)
• Rain-Clik® Sensor (wired and wireless)
• Soil-Clik® Sensor
• Solar Sync® Sensor (wired and wireless)
• Wind-Clik® Sensor

All Hunter Clik Sensors are normally closed and open on alarm, which alerts the controller to suspend watering. The controller can be programmed to shut down the entire controller, or only individual stations, once the sensor is triggered (see Programmable Sensor Override instructions).

1. To connect a Hunter Clik Sensor, locate the weather sensor input (⚡) on the power module.
2. Route the wires from the Clik Sensor through any of the available knockouts into the controller cabinet.
3. Remove the red jumper wire that is attached across the weather sensor input (⚡) and common terminal (C).
4. Connect one wire to the weather sensor input (⚡) and the other wire to the C terminal on the top of the power module.

Sensor Bypass Switch

This switch will either enable or disable a weather sensor that has been connected to the controller. When the switch is in the "Active" position, the controller will adhere to the state of the sensor and shut down irrigation if the sensor is triggered. If the sensor is in a closed state, the controller will operate as normal. If the sensor is in an open state, but you would like your automatic irrigation to operate as normal, simply move the switch to the "Bypass" position. The sensor will now be overridden, and the controller will operate as programmed.

If you do not have a sensor installed, the position of the Sensor Bypass Switch can be in either Active or Bypass mode. This is true as long as the jumper wire connecting the weather sensor terminal to common remains in place. If a jumper wire has been removed, keep the Sensor Bypass Switch in the Bypass mode. Otherwise, no automatic irrigation will occur.

Note: The Manual Single Station function ignores any attached sensor and will allow manual watering to occur.

Note: The Sensor Bypass Switch must be set to "Active" for the controller to react to a sensor alarm. Once an alarm is triggered, the display will read OFF and show a solid ? symbol. If no sensor is installed, you must reinsert the jumper wire on the SEN terminals or set the Sensor Bypass Switch to "Bypass." ⚠️

Connecting a Hunter Solar Sync Sensor (Not Included)

When connected to an ICC2 Controller, the Solar Sync Sensor will automatically adjust your programmed watering schedule based on changes in local climate conditions. It utilizes a solar radiation and temperature sensor to measure on-site weather conditions and determine evapotranspiration (ET), which is the rate at which plants and turf use water. In addition, the Solar Sync Sensor also includes a Hunter Rain-Clik and Freeze-Clik Sensor that will shut down the irrigation system during rainy and/or freezing conditions.

For further programming instructions, refer to the Solar Sync Owner's Manual or visit the Solar Sync support section: hunter.help/SolarSync

Wired Solar Sync Installation

1. Using the screws provided, mount the sensor in the upright position on a surface exposed to direct sun and rainfall, away from sprinkler spray and within 200' (60 m) of the controller.
2. Route the green and black wire pair through any of the available knockouts into the controller cabinet.
3. Remove the red jumper wire that is attached across the weather sensor input (⚡) and common terminal (C).
4. Connect either wire to the weather sensor input (⚡) and the second wire to the C terminal on the top of the power module.

Wireless Solar Sync Installation

1. Repeat steps 1-4 above. However, you'll connect the green and black wires from the Wireless Solar Sync Receiver to the weather sensor input, as opposed to wires coming from the sensor.
2. The receiver can be mounted in the knockouts on the side of the controller or to a wall using the wall mounting bracket and hardware provided.
3. The sensor can be mounted up to 800' (240 m) from the receiver, which is pre-paired to the same frequency. Once installed, the receiver enters "search" mode to detect the paired sensor. Manually initializing communication during setup is recommended to confirm signal transmission.
4. After the receiver's green and black wires have been connected to the controller, the red LED in the center of the receiver will activate and remain solid for 10 seconds, indicating that it's searching for a signal from the sensor.
5. While the receiver is searching, press and hold the spindle on the sensor. The LED on the receiver will blink four times and then turn off, indicating that the signal from the sensor has been acknowledged.
6. To double-check or validate existing receiver/sensor communication, press and hold the spindle on the sensor. The LED on the receiver will blink twice, confirming that the receiver is addressed to the sensor properly.

Connecting a Hunter Flow Sensor (Optional)

I2CF-800 Series Controllers include built-in flow monitoring capabilities and two sensor inputs: one for a flow sensor and the other for a Clik/Solar Sync Sensor. These sensor inputs wire separately across the Common terminal on the Power Module, designated by a flow icon and a weather icon. All flow monitoring is enabled and configured at the ICC2 Controller facepack.

Note: All flow-monitored stations must have a Run Time set prior to the flow learning process. Any stations without a Run Time will not be included in the calibration.

1. Route flow sensor wires from the field into the controller cabinet through any of the available conduit knockouts.
2. Connect either wire to the flow sensor input (⚡) and the second wire to the C terminal on the top of the power module.
3. Complete flow setup and monitoring configuration at the controller facepack.

Connecting a Hunter Remote (Not Included)

The ICC2 Controller is compatible with both Hunter ROAM and ROAM XL Remotes, and each controller comes with a factory-installed SmartPort Wiring Harness. This provides instant remote connection capability, which enables manual system operation without walking back and forth to the controller.

1. To connect either a ROAM or ROAM XL Remote Kit to your controller, simply remove the weather-resistant rubber cover on the SmartPort, align the remote receiver's pins with the connector, and push firmly until the receiver is fully seated.
2. Each ROAM and ROAM XL System is preaddressed to work right out of the box. Once you install the receiver into the SmartPort Wiring Harness, it will beep four times. After approximately 7 seconds, the receiver will again beep twice to confirm it's programmed to the correct address. To verify that the transmitter and receiver are communicating properly, press either the [▶] or stop button on the transmitter. The receiver should beep twice, indicating proper communication. If the receiver does not beep, check the batteries in the transmitter and repeat the process.

Manual Operation of a Single Station

1. Turn the dial to the Manual position.
2. The station run time will flash in the display. Press the [▶] button to advance to the desired station.
3. Press the [+] and [-] buttons to select run time duration from 1 minute to 12 hours.
4. Turn the dial to the Run position, and the station will begin watering. Only the designated station will water for its specified duration. Once completed, the controller will return to automatic run mode with no changes to the previously set program.

Note: The Manual Single Station function ignores any attached sensor and will allow watering to occur. Do not use Manual Single Station to test a rain sensor. Use Run Program and One-Touch Manual Start instead.

Setting System Off

To stop all irrigation, including any stations which are already running, turn the dial to the System Off position. OFF will appear on the display and, within a few seconds, any running stations will shut down. No automatic programs can start while the controller is set to System Off. To return the controller to normal operation, simply reset the dial to the Run position.

Programmable Rain Off

This feature stops all programmed watering for a designated period from 1 to 99 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, and wait for the OFF to stop flashing.
2. Press the [+] and [-] buttons to set the number of days to remain off.
3. Turn the dial back to the Run position. The display will show how many days off remain. The days off remaining will decrease by one at midnight of each day. Once the display reaches 0, it will revert to show the normal time of day, and automatic irrigation will resume at the next scheduled start time.

Note: To cancel Programmable Rain Off settings, turn the dial to the System Off position, wait for the OFF to stop flashing, then return the dial to the Run position.

Programmable Sensor Override

The ICC2 Controller can be programmed to enable an independent sensor response for each station. This feature allows the sensor to disable watering for only the desired stations (as opposed to the entire system). For example, patio gardens or other landscapes that are underneath overhangs or roofs may not receive water when it rains and will still need to be watered during periods of rain.

Note: The controller default setting is ON, which means the sensor is active and will disable watering on all zones once the sensor is triggered.

1. With the dial in the Run position, press and hold the [-] button, turn the dial to the Start Times position, and release the [-] button.
2. The display will show the station number, and ON will flash. Press the [+] and [-] buttons to enable or disable the sensor for the station shown.

ON = sensor enabled (will suspend irrigation)
OFF = sensor disabled (will allow watering)

3. Use the [◀] and [▶] buttons to scroll to the next desired station for Sensor Override.
4. Rotate the dial back to the Run position when finished programming all Sensor Overrides.

Cycle and Soak

The Cycle and Soak feature splits a station's run time into cyclical, shorter watering durations. This feature is useful when applying water to slopes and tight soils because it automatically slows the application of water by irrigating with multiple shorter cycles, as opposed to one long run time. This helps to prevent runoff and excessive watering.

To do this, enter the Cycle time as a fraction of the station's total watering duration and the Soak time as the minimum number of minutes before the next cycle begins. The total number of cycles is calculated by dividing the programmed station run time by the Cycle time.

Consider an example where Station 1 requires 20 minutes of watering. If runoff occurs after 5 minutes yet all water is absorbed into the soil after 10 minutes, the solution is to set a 20-minute Run Time, 5-minute Cycle time, and 10-minute Soak time. This creates four 5-minute watering cycles with 10-minute Soak periods in between.

If other stations are programmed after Station 1, the Cycle and Soak process for Station 1 will finish after all other zones have run. The controller will run Station 1's first cycle, proceed sequentially through the remaining stations, then return to Station 1 to complete its remaining Cycle and Soak schedule.

1. To access the Cycle and Soak menu, begin with the dial in the RUN position. Press and hold the [+] button, turn the dial to the Run Times position, and release the [+] button.
2. Initially, Station 1 will display. To access other stations, press the [◀] or [▶] buttons. Once the desired station is shown, use the [+] and [-] buttons to increase or decrease the Cycle time. Set the Cycle time from 1 minute to 4 hours or OFF if no Cycle and Soak schedule is desired.

Note: When setting both Cycle and Soak times, times less than 1 hour will display in minutes only (e.g., 30). For times greater than 1 hour, the display will change to include hours and minutes (e.g., 2:45).

Delay Between Stations

This feature allows the user to program a delay between station activation and shutoff. This is particularly helpful on systems with slow-closing valves, pumps that are operating near maximum flow, and/or alternate water sources with slower recovery, such as wells and water storage tanks.

1. With the dial in the Run position, press and hold the [-] button, turn the dial to the Run Times position, and release the [-] button.
2. The display will show a delay time in seconds, which is default set to 00 seconds. Press the [+] and [-] buttons to increase or decrease the delay times. For any delay time less than 1 minute, the display will show only seconds (e.g., SEC 45). Once you program over 59 seconds, SEC will change to "Hr" and the delay time converts into minutes and hour mode (e.g., Hr 0:30 represents 30 minutes, Hr 2:00 represents 2 hours).
3. The Delay Between Stations feature applies to all stations and can be programmed from 1 second to 10 hours.
4. Rotate the dial back to the Run position when finished programming all Delays Between Stations.

Note: The Master Valve/Pump Start circuit will remain active during the first 15 seconds of any programmed Delay Between Stations to aid in the closing of the valve and to avoid unnecessary cycling of the pump.

Hide Programs

The ICC2 Controller is factory configured with four independent programs (A, B, C, and D) that are utilized when watering multiple different landscapes and plant-type requirements. The controller can be customized to display only the most basic programming, and thus, hide extra programs.

1. With the dial in the Run position, press and hold the [-] button, turn the dial to the Water Days position, and release the [-] button.
2. Use the [+] and [-] buttons to change between either 4 or 1. The default setting is set to 4, which shows all 4 programs available and all 8 start times available. Switching to a setting of 1 will show only program A and only 1 start time.
3. Rotate the dial back to the Run position when finished programming all Hide Programs.

Solar Sync Delay

The ICC2 Controller with built-in Solar Sync programming has the ability to delay the automatic, daily update of the Seasonal Adjustment value from Solar Sync for up to 99 days. This option may be advantageous to users who do not want Solar Sync to adjust program run times for a specific period of time (e.g., during an overseeding or overwatering schedule). This function allows the controller to operate with a manually set, fixed Seasonal Adjustment value, at least until the Solar Sync Delay period expires. However, even while Solar Sync Delay is active, the Solar Sync Sensor will continue to gather weather information and calculate the Seasonal Adjust Value; it just won't be applied to the run times. Once the Solar Sync Delay ends, the updated Seasonal Adjust value will be applied.

Note: The Solar Sync Delay feature is only accessible when a Solar Sync Sensor is installed.

1. With the dial in the Run position, press and hold the [+] button, turn the dial to the Solar Sync position, and release the [+] button.
2. The display will show "d:00," where "d" indicates days and "00" indicates the number of days to be delayed.
3. Press the [+] or [-] buttons to increase or decrease the number of Solar Sync Delay days you desire. Once the correct number of days is displayed, return the dial to the Run position.

Note: The number of days remaining will not be displayed on the Run screen. To check if the Solar Sync Delay feature is active, open the Solar Sync Delay menu and check the number of days shown. If 1 or more days are programmed, then Solar Sync Delay is active, but if 0 days are programmed, then Solar Sync Delay is disabled.

Clik Delay

This feature allows the user to delay programmed watering for a designated period of time AFTER a Clik event occurs. For example, heavy rain is in the forecast and you won't need to irrigate for multiple days after the storm. The Clik Delay can postpone automatic programming from 1-7 days after the Clik Sensor is triggered. At the end of the Clik Delay period, the controller will resume normal automatic watering.

1. With the dial in the Run position, press and hold the [+] button, turn the dial to the System Off position, and release the [+] button.
2. The display will show "OFF –" with the dash blinking. Press the [+] or [-] buttons to increase or decrease the number of Clik Delay days. Once the correct number of days is displayed, return the dial to the Run position.
3. After a Clik event ends (e.g., the rain sensor dries out and deactivates the sensor), the Clik Delay feature will become active and will display on the screen for the entire Clik Delay duration.

Note: An active Clik Delay can be canceled at any time by simply turning the dial to the System Off position, waiting for "OFF" to stop blinking, and returning the dial to the Run position. Also, any station that is set with the Programmable Sensor Override feature will operate during a Clik Delay.

Total Run Time

The ICC2 Controller keeps a running total of each program's station run times. This feature provides a quick way to determine how long each program will irrigate.

1. Turn the dial to the Run Times position.
2. From the Station 1 run time, press the [▶] button once to review the total of all run times in the program. You can also view the total run time by pressing the [▶] button once after advancing to the highest station run time.
3. Press the [PRG] button to review total run times of additional programs.

Test Program

The Test Program feature offers users a simplified method for manually starting any or all stations sequentially. This feature operates each station in numerical order, from lowest to highest, and can be started from any specific station. This is beneficial for quick operation of your irrigation system.

1. With the dial in the Run position, press and hold the [PRG] button. Station 1 will appear with a run time flashing (controller default is set to 0:00).
2. Press the [◀] and [▶] buttons to select the station you'd like to run first. Press the [+] and [-] buttons to increase or decrease the station run time (0 to 15 minutes). The run time entered will be applied to all stations.
3. After a two-second pause, the Test Program will begin. You can advance forward and backward through the stations if you don't need a particular zone to run for the full duration.

Easy Retrieve® Memory

The ICC2 Controller is capable of saving the preferred watering program into memory for retrieval at a later time. This feature creates a quick way to reset the controller to the original programmed watering schedule, and it's particularly beneficial when overwriting any unwanted changes to the current program.

1. With the dial in the Run position, press and hold the [+] and [PRG] buttons simultaneously. Once three dashes appear on the screen, release the [+] and [PRG] buttons. The symbol will scroll left to right across the display indicating the program is being saved into memory. The display will show DONE once saved, and it will then revert back to the time-of-day display.
2. To retrieve a program that was previously saved into memory, leave the dial in the Run position and press and hold the [-] and [PRG] buttons simultaneously. Once the same three dashes appear on the screen, release the [-] and [PRG] buttons. The symbol will scroll right to left across the display indicating the program is being loaded from memory. The display will show DONE once loaded, and it will then revert back to the time-of-day display.

Total Reset

The Total Reset feature will erase all of the controller's memory and set everything back to factory presets. Once you perform a Total Reset, all programming will be completely erased, including any Easy Retrieve programming that may have been saved. This feature is typically utilized when you need to reprogram the controller from the beginning or if the controller is not responding to any commands.

1. Press and hold the [PRG] button.
2. Press and release the "Reset" button.
3. Continue to hold the [PRG] button until the word DONE is displayed on the screen.

QuickCheck™ Technology

This circuit diagnostic procedure can quickly identify wiring shorts commonly caused by faulty solenoids and poor or incorrect wire splices. QuickCheck is an efficient and effective way to diagnose problems in the field, instead of physically checking each wiring circuit for potential problems.

1. To initiate the QuickCheck test procedure, press the [+], [-], [◀], and [▶] buttons simultaneously. The display will show all icons on the screen.
2. Press the [+] button to begin the diagnostics. The controller will then search all stations to detect a high current path through the station terminals. When a field wiring short is detected, an ERR message preceded by the station number will flash momentarily on the display. The test will continue checking the remaining stations for faults and, once completed, will return to automatic watering mode.

Run Program (One-Touch Manual Start)

The ICC2 Controller is also capable of activating an entire program without using the dial. This option 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. The Run Program feature differs from the Test Program feature by allowing you to select any of the four automatic programs to run the existing run times.

1. With the dial in the Run position, press and hold the [▶] button for two seconds then release.
2. This manual one-touch start option automatically defaults to program A. You can select any of the four programs (A, B, C, or D) by pressing the [PRG] button.
3. The station number will flash on the display. Press the [◀] and [▶] buttons to scroll through the stations and the [+] and [-] to adjust the preexisting run times (0 minutes to 12 hours). Once you've selected the desired station to run first, the program will begin automatically. You can advance forward and backward through the stations if you don't need a particular zone to run for the full duration.
