The I-Core features a ground lug, which is isolated from the primary AC power, and is used to ground incoming surges from the communications and output valve wires.

Do NOT connect the primary AC 120/230V electrical ground wire to the earth ground lug.

1. Use #10 (6 mm) or #8 (10 mm) bare wire to connect the controller to the ground rod. Route the earth ground wire into the wiring compartment through the 1 ½" conduit opening at the bottom of the cabinet. Do not route the ground wire through the same conduit as the incoming primary AC power.

2. Loosen the ground lug screw; insert the ground wire into the ground lug and tighten the screw to secure the ground wire. Do not over tighten.

Acceptable grounding consists of an 8' (2.5 m) copper-clad rod or stake, or a 4" x 96" (100 mm x 240 cm) copper plate, or both, placed in the earth at least 8' (2.5m) away from the controller, and with the ground wire at right angles to the communications and valve wires, if possible. Ideal grounding resistance would be 10 Ohms or less as measured with a “megger” or similar device. Please consult the ASIC reference for more detailed information on proper grounding techniques.

Connecting Station Valve Wires

Each station module that has been inserted has a grouping of six station screw terminals corresponding to that particular expansion slot. Once a station module is installed in a module slot, the station screw terminals assigned to that module, which are located directly below the station module, become active.

Each station output is rated for 0.56A max, or enough to operate two Hunter AC solenoids simultaneously.

1. Route valve wires between control valve location and the controller.

2. At the valves, attach a common wire to either solenoid wire of all the valves. This is most commonly a white colored wire. Attach a separate control wire to the remaining wire of each valve. All valve wire splice connections should be done using waterproof connectors.

3. Open the faceplate at the controller to expose the numbered station terminals.

4. Route valve wires through the conduit and attach the conduit to the controller at the 1 ½" (37.5 mm) opening at the bottom of the cabinet.

5. Strip ½" (13 mm) of insulation from the ends of all the wires. Secure the valve common wire to one of three C (Common) terminals located of the Power and Accessory terminals. All three common terminals are active, so the valve common wire may be connected to either one. Attach all the individual valve control wires to the appropriate station terminals.

Valve Wires

Valve 4

The Master Valve or Pump Start Relay connection is located on the bottom row of the Power and Accessory Terminals, and is labeled P/MV. This terminal will supply 24 VAC, 0.32A max, for a single Master Valve solenoid. For a Pump Start Relay, the relay holding current draw must not exceed 0.28 amps. If using a Pump Start Relay, it is recommended that the controller be mounted at least 15' (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. Do not connect the controller directly to the pump — damage to controller will result.

1. Route valve wires between Master Valve or Pump Start Relay location and the controller.

2. At the Master Valve, attach a common wire to either solenoid wire of the valve. Attach a separate control wire to the remaining solenoid wire. At the Pump Start Relay, attach either wire to one of the yellow wires coming from the Pump Start Relay. Attach the remaining wire to the other yellow wire at the Relay. All wire splice connections should be done using waterproof connectors.

3. Open the inner facepack door at the controller.

4. Route the valve wires into the controller via the eld wire conduit.

5. Connect either wire from the Master Valve or Pump start Relay to the P/MV terminal located on the bottom row of the Power and Accessory terminals. Connect the remaining wire to the C (Common) terminal that is located directly to the left of the P/MV terminal.

The Master Valve or Pump Start Relay can be activated according to a particular station. The conguration of assigning the Master Valve or Pump Start Relay according to a particular station will be covered in the Set Pump Operation (pg. 18).

Connecting a Master Valve or Pump Start Relay

Complete this section only if you have a Master Valve or Pump Start Relay installed. The I-Core controller works with a normally closed master valve that is typically installed at the supply point of the main line that opens only when the automatic system is activated. A pump start relay is an electrical device that uses the irrigation controller to activate a pump to provide water to your system.

CONNECTING A WEATHER SENSOR (OPTIONAL AND NOT INCLUDED)

S1 S1 S2 S2 C C

GND AC1 AC2 REM C

P/MV

The I-Core controller has the ability of connecting two Hunter Sensors (three with I-Core Metal) including:

• Mini-Clik

• Rain Clik™ (including Wireless Rain Clik, Wireless Rain Freeze-Clik)

• Freeze-Clik

• Wind-Clik

• Mini-Weather Station (MWS)

• Solar Sync and Wireless Solar Sync ET Sensor

With the I-Core controller, Clik sensors can be programmed to shut down individual stations, not necessarily the entire controller. Each sensor can be given its own response instructions according to each station. Hunter Clik sensors are usually normally closed, and open on alarm. This signals the controller to suspend watering when precipitation, freeze or wind events occur. The sensor connects directly to the sensor terminals, which also allows you to override the sensor by using the Rain Sensor bypass switch on the face of the controller.

1. To connect Clik sensors, locate the 2 pairs of sensor terminals in the Power and Accessory Terminal section, labeled S1, S1 and S2, S2 (S3 available on I-Core Metal).

2. Route the wires from the Clik sensor through any of the available knockouts into the controller cabinet.

3. The sensor connections are made in dedicated pairs. Remove the sensor jumper wire from one pair of S1 or S2 terminals. Attach one sensor wire to each of the two S1 or S2 terminals.

4. To connect the Wireless Rain Clik or Wireless Rain Freeze Clik, the blue and white wires will be connected to the corresponding sensor terminal as stated above: One into the rst S1 terminal and the other into the second S1 terminal. Connect one of the yellow wires to the AC1 terminal and the other yellow wire to the AC2 terminal.

Bypassing the Sensor(s)

If the rain sensor is ACTIVE and automatic or manual operation is required, simply move the Bypass switch to Bypass.

Weather Sensor

If the rain sensor switch is left in the ACTIVE position but no sensor is connected and the jumper wire has been removed, the display on the I-Core will indicate that the sensor is ACTIVE. This will also be indicated in the System Status dashboard to the left of the display. The sensor light will be illuminated RED for ACTIVE, thus having an open circuit. As long as the sensor is in the ACTIVE mode, any station that has been programmed to the ACTIVE sensor will not be allowed to water, and will be put into Suspend mode. If you do not have a sensor and want to eliminate this possible problem, simply keep the rain sensor switch in the bypass mode, or install the jumper wire between the sensor terminals if it has been removed.

Programming of the sensors will be discussed in the Set Sensor Operation section of Programming and Operation (pg. 18).

Sensor Bypass Switch

This switch will either enable or disable a Rain or Freeze 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 in an open state. 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.

Once the Sensor Bypass Switch is in the Active position the System Status Dashboard will acknowledge the switch is in the Active position, and the Sensor Status light will light up. If the sensor is in an open state, the System Status Sensor light will be Red. If the sensor is in a closed state, the System Status Sensor light will be Green.

If you do not have a sensor installed, the position of the Rain Sensor switch can be in either the Active or the Bypass mode. This is true as long as the jumper wire connecting the two sensor terminals remain in place. If a jumper wire has been removed, it will be necessary to keep the Rain Sensor switch in the Bypass mode, otherwise no automatic irrigation will occur.

CONNECTING A HUNTER SOLAR SYNC

The Solar Sync is a “smart“ control system that, when connected to the I-Core, will automatically adjust your controller’s station run times based upon changes in local climate conditions. The Solar Sync incorporates a solar and temperature sensor to determine evapotranspiration, also known as ET. It also utilizes a Rain Clik and Freeze-Clik to shut down your irrigation when conditions arise.

The I-Core now has the Solar Sync software built into the controller. New I-Core controllers with built in Solar Sync are easily identied by the new SOLAR SYNC SETTINGS dial position on the facepack. Because the new I-Core has built in Solar Sync software, the Solar Sync Sensor is the only item to be connected to the controller. The Solar Sync module will not be

used and is not compatible with I-Core controllers that have Solar Sync software built in.

1. To connect the Solar Sync Sensor route the black and green sensor wires into the controller and connect them to the two S1 terminal positions. It does not matter which wire goes to which S1 terminal, but

the S1 terminal must be used when connecting a Solar Sync sensor.

2. Mount the Solar Sync sensor in a location that receives as much sunlight as possible for best results. (see Solar Sync owner’s manual for more details on sensor location)

3. The Solar Sync Sensor must now be assigned to the SEN1 location in the controller. Turn the dial to the ADVANCED FEATURES position.

4. Use the ▼ button to scroll to Sensor Conguration and press the + button.

5. In the SEN1 position use the + button to scroll through the options until Solar Sync is shown. The I-Core now recognizes that a Solar Sync sensor has been connected.

SOLAR SYNC Module

Do not install

If connecting a

Wireless Solar Sync

to the I-Core, steps 1-5 are the same except in step 1, you will be connecting the green and black wires from the Wireless Solar Sync Receiver to the S1 terminal positions. The Wireless Solar Sync Receiver then communicates with the Wireless Sensor.

The Solar Sync can be programmed to adjust station run times by program. To set the I-Core to Solar Sync Adjust mode:

1. Turn the dial to Set Seasonal Adjustment. Use the PRG Button to

select the desired program.

2. Press the +/– button to select By Solar Sync Seasonal Adjust mode.

Repeat for other programs if needed (See Sensor Conguration on page 22).

Once a Solar Sync is connected and programmed the station run times will be adjusted according to the ndings of the Solar Sync. The Solar Sync will automatically adjust station run times and can be programmed independently for each of the four I-Core programs. The Rain Clik and Freeze-Clik sensor incorporated in the Solar Sync can be programmed by station which is discussed in the Set Sensor Operation section.

(1 mm) wires from the sensor into the cabinet (max distance of 1,000 ft.).

2. Locate a pair of S1 or S2 (S3 available on I-Core Metal) sensor red and

black terminals on the Power and Accessories Terminals. Remove the jumper wire from one pair or S1 or S2 terminals. You may use either pair of S1 or S2 sensor terminals for a ow sensor. Connect the red wire from the HFS to the red terminal, and the black wire from the HFS to the black terminal.

3. I-Core allows you to connect two ow sensors at one time. In that

case, one of the ow sensors would connect to the red S1 terminal and the black S1 terminal, while the second ow sensor would connect to the red S2 terminal and the black S2 terminal.

NOTE: I-Core has only one Pump/Master Valve output. If 2 ow sensors are used on 2 different points of connection, only one of them will have a master valve available for alarm shutdowns unless the single PMV is congured to operate 2 master valves simultaneously.

Flow setup, learning, and conguration will be described later in the manual under Advanced Features (pg. 22). A complete step by step Flow Monitoring procedure is also available in the Hidden Features section (pg. 29).

NOTE: If a ow sensor is going to be connected to the controller and ow will be monitored, there is critical information that needs to be read in the Controller Diagnostics and Troubleshooting section under System Status Dashboard Flow. It is very important to understand how the controller will monitor ow under certain circumstances and what diagnostic testing will be performed in alarm situations.
