MOUNTING THE CONTROLLER TO WALL Note: The indoor version of the X-Core® is not waterproof or weather resistant, and must be installed indoors or in a protected area. B A 1. Secure one screw into the wall. Install screw anchors if attaching to drywall or masonry wall. 2. Slide the keyhole on top of the controller over the screw. 3. Secure the controller in place by installing screws in the holes below the terminal strip.
CONNECTING VALVES AND TRANSFORMERS Installation of the X-Core® should only be done by trained personnel. Valve 4 1. Route valve wires between the control valve location and controller. 2. At valves, attach a common wire to either solenoid wire on all valves. This is most commonly a white colored wire. Attach a separate control wire to the remaining wire of each valve. All wire connections should be done using waterproof connectors. Valve 3 BAT Valve 2 3. Route the valve wires through the conduit.
ACTIVATING THE BATTERY After installing your X-Core®, make sure to remove the battery contact insulator to allow the X-Core to keep time in the event of a power outage. CAUTION: RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS. REPLACING THE BATTERY A high-energy lithium battery is included with your X-Core controller. The battery allows the user to remotely program the controller Lithium Battery without connecting AC power.
CONNECTING A MASTER VALVE 1. NOTE: Complete this section only if you have a master valve installed in your irrigation system. A master valve is a “normally closed” valve installed at the supply point of the main line that opens only when the controller initiates a watering program. t the Master Valve, attach the common wire to either solenoid wire A of the valve. Attach a separate control wire to the remaining solenoid wire. 2. The common wire should be attached to the C terminal inside the controller.
CONNECTING A PUMP START RELAY NOTE: Complete this section only if you have a pump start relay installed. A pump start relay is a device that uses a signal from the controller to actuate a separate electrical circuit to energize a pump to provide water to your system. The controller should be mounted at least a 15 ft (4.5 m) away from both the pump start relay and pump to minimize any potential electrical interference. 1. Route a pair of wires from the pump relay into the controller. 2.
CONNECTING A HUNTER "CLIK" WEATHER SENSOR A Hunter weather sensor or other micro-switch type weather sensors can be connected to the X-Core®. The purpose of this sensor is to stop automatic watering when weather conditions dictate. When the weather sensor has deactivated automatic watering, the OFF, and icon will appear on the display. 1. Remove the metal jumper plate that is attached across the two SEN terminals inside the controller. Testing the Weather Sensor 2.
CONNECTING A HUNTER SOLAR SYNC® ET SENSOR The X-Core® is compatible with the Solar Sync and Wireless Solar Sync systems. Solar Sync is a sensor system that will automatically adjust the X-Core 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 Water Adjustment Uninstalling a Solar Sync® Sensor The Water Adjustment is a 1 to 10 scale that allows for easy adjustment of the Seasonal Adjust value from the Solar Sync ET Sensor. Upon installation of the Solar Sync ET Sensor, it is recommended that the Water Adjustment setting stay at the default value of 5.
CONNECTING A HUNTER SOLAR SYNC® ET SENSOR Calibration/Setup After Solar Sync has been installed and programmed, it is recommended to 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 in order to arrive at the desired performance.
CONNECTING A HUNTER REMOTE Connecting to a Hunter Remote (not included) The X-Core® Controller is compatible with Hunter Remote Controls (not included). The SmartPort® wiring harness (included with all Hunter Remotes) allows for fast and easy use of the Hunter controls. The Hunter remotes make it possible for you to operate the system without having to walk back and forth to the controller. 4.
PROGRAMMING THE CONTROLLER The X-Core display shows the 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 the or buttons until the desired field is flashing.
PROGRAMMING THE CONTROLLER Setting the Program Start Time(s) Setting Station Run Times 1. Turn the dial to the START TIMES position. 1. Turn the dial to RUN TIMES position. 2. The factory preset is set on program A. If necessary, you can select program B, or C by pressing the button. START TIMES or button to change the 3. Use the start time. (The start times advance in 15 minute increments). 4. Press the button to advance to the next station.
PROGRAMMING THE CONTROLLER Selecting Specific Days of the Week to Water Selecting Interval Watering 1. With the cursor on a specific day (the cursor will always start with MO), press the button to activate a particular day of the week to water. Press the button to cancel watering for that day. After pressing a button the cursor automatically advances to the next day. With this option you can select interval watering from 1 to 31 days. Mo Tu We Th Fr Sa Su 2.
PROGRAMMING THE CONTROLLER Setting Event Day(s) Off System Off The X-Core allows you to program a No Water Day(s). This feature is useful to inhibit watering on specific day(s). For example, if you always mow the lawn on Saturdays, you would designate Saturday as a No Water Day so that you are not mowing wet grass. 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.
PROGRAMMING THE CONTROLLER When using a Hunter “Clik” weather sensor, the Seasonal Adjustment value can be adjusted as described. Seasonal Adjustment Seasonal Adjustment is used to make global run time changes without re-programming the entire controller. To use the Seasonal Adjustment feature: 1. Turn the dial to the SEASONAL ADJUSTMENT position. 2. The display will now show a flashing number followed by a %, as well as the bar graph which always remains on the or button to display.
PROGRAMMING THE CONTROLLER Manually Run a Single Station One Touch Manual Start and Advance 1 1. Turn dial to MANUAL – ONE STATION position. You can also activate all stations to water without using the dial. 2. Station run time will flash in the display. Use the button to move to the desired station. You may use the or button to select the amount of time for a station to water. 1. Hold down the MANUAL-ONE STATION 1 3.
ADVANCED FEATURES Programmable Sensor Override Test Program of All Stations The X-Core 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: The X-Core allows the user a simplified method for running a test program.
ADVANCED FEATURES Easy Retrieve™ Program Memory Programmable Delay Between Stations The X-Core 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. This feature allows the user to insert a delay between stations between when one station turns off and the next one turns on. ® To save the program into the memory 1.
ADVANCED FEATURES Cycle and Soak The Cycle and Soak feature is an enhancement to the existing X-Core® controller. It is designed to afford customers the ability to minimize runoff due to different soil and terrain characteristics. The Cycle and Soak feature allows you to split a station’s runtime into shorter watering periods. The shorter watering periods will help prevent run off in situations like slopes or tight soils.
ADVANCED FEATURES Cycle and Soak Situations Setting the Soak Time 1. 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 button to return. 2. Once the desired station is displayed, the user can use the or button to increase or decrease the Soak time.
