4. Setup and Installation

4.1. Mounting the Controller

Select a suitable outdoor location for the controller, away from direct sunlight and extreme weather conditions. Ensure it is within reach of a power outlet and your irrigation valve wiring. The outdoor model features a weather-resistant casing.

1. Open the controller's front door.
2. Use the provided mounting template (if available) or hold the controller against the wall and mark the positions for the mounting screws.
3. Drill pilot holes and insert the appropriate wall anchors if necessary.
4. Drive a screw into the top marked position, leaving approximately 1/8 inch (3 mm) of the screw head exposed.
5. Hang the controller onto the top screw using the keyhole slot on the back.
6. Secure the controller by driving additional screws through the bottom mounting holes.

4.2. Wiring the Controller

Ensure all power is disconnected before proceeding with wiring. The XC800 supports up to 8 irrigation zones.

1. Connect Valve Wires: Route the common wire (usually white) from your irrigation valves to the terminal marked 'C'. Connect each individual zone valve wire to its corresponding numbered terminal (1-8).
2. Connect Power: The outdoor model has an integrated transformer. Connect the power cord from the controller to a suitable outdoor-rated electrical outlet.
3. Sensor Connection (Optional): If using a rain sensor or Solar Sync ET sensor, refer to the sensor's instruction manual for wiring to the 'SEN' terminals. The controller features a sensor bypass switch.

5. Operating Instructions

The X-Core controller features a simple rotary dial and push buttons for programming. Turn the dial to the desired function and use the arrow buttons (+/-) to adjust settings.

5.1. Dial Positions:

• System Off: Turns off all automatic watering.
• Manual: Allows for manual operation of individual stations or programs.
• Solar Sync: (If optional sensor is installed) Adjusts watering based on local weather.
• Seasonal Adjust: Manually adjusts all program run times by a percentage.
• Date/Time: Set current date and time.
• Start Times: Set program start times (up to 4 per program).
• Run Times: Set watering duration for each station.
• Water Days: Select specific days of the week for watering.

5.2. Basic Programming Steps:

1. Set Date and Time: Turn the dial to 'Date/Time'. Use the arrow buttons to set the year, month, day, and current time.

3. Set Run Times: Turn the dial to 'Run Times'. Select a program and then use the arrow buttons to set the watering duration for each station (1-8).
4. Set Water Days: Turn the dial to 'Water Days'. Select a program and use the arrow buttons to choose specific days of the week, odd/even days, or interval watering.

6. Maintenance

The Hunter XC800 X-Core is designed for minimal maintenance. Periodically check the wiring connections for any signs of corrosion or damage. Ensure the controller door is securely closed to protect against environmental elements. If the display is blank or erratic, check the power supply and the internal battery (if applicable for memory backup).

7. Troubleshooting

• No Display: Check the power connection to the transformer and ensure the outlet is functional. Verify the transformer is supplying 24 VAC to the controller terminals.
• Stations Not Watering: Ensure the dial is set to 'Run'. Check the wiring connections for the affected stations and the common wire. Use the Hunter Quick Check feature to diagnose wiring faults.
• Watering at Wrong Times: Verify 'Date/Time', 'Start Times', and 'Water Days' settings are correctly programmed.
• Continuous Watering: Check for a stuck valve or a short in the wiring. Turn the dial to 'System Off' to stop watering immediately.
