Key Features and Compatibility

The Hunter Node 100 controller offers a range of features, including a battery-operated design with a long-lasting power option using one or two 9-volt batteries. It supports DC latching solenoids, which are essential for its operation, and is compatible with Hunter plastic valves. The controller can be easily mounted using a specially designed valve mounting clip, ensuring a secure and straightforward installation. Additionally, it integrates seamlessly with Hunter’s Mini-Clik and Rain-Clik rain sensors, allowing for weather-based irrigation adjustments. The Node 100 is also part of a family of controllers that includes the Node 200, 400, and 600, which support multi-station operations. Its compatibility with various Hunter products makes it a versatile choice for both new installations and retrofits.

Installation and Setup

The Hunter Node 100 installation involves wiring DC solenoids and mounting the controller to a valve using a specially designed clip. A protective rubber cover is provided to prevent dirt accumulation, ensuring smooth operation.

Wiring DC Solenoids to the Node

Wiring DC solenoids to the Hunter Node 100 is straightforward but requires attention to detail. The Node 100 operates with DC latching solenoids, which are essential for proper functionality. Ensure the solenoid is compatible, as 24VAC solenoids will not work with the Node. The maximum wire distance between the solenoid and the Node is 100 feet using 18 AWG wire. To wire the solenoid, connect one wire to the Node’s terminal and the other to the common wire. Use a DC latching solenoid operating between 9-11 VDC for reliable operation. Proper wiring ensures efficient control of irrigation systems and prevents potential malfunctions. Always follow the manufacturer’s guidelines for connections to maintain optimal performance and longevity of the controller.

Mounting the Node to a Valve

Mounting the Hunter Node 100 to a valve is a straightforward process that ensures secure and efficient operation. Begin by locating the specially designed valve mounting clip provided with the Node. This clip is designed to fit seamlessly onto any Hunter plastic valve, allowing for easy installation without the need for additional tools. To attach the Node, simply snap the mounting clip onto the valve, ensuring it is securely fastened. For added protection, install the provided protective rubber cover over the Node’s face to prevent dirt and debris from interfering with its buttons and display. Ensure the Node is oriented for easy readability, typically facing upwards or towards the user. After mounting, test the Node by running a quick test program to verify that the solenoid responds correctly, ensuring proper irrigation control.

Programming Capabilities

The Hunter Node 100 offers standard Hunter controller programming with 3 programs (A, B, C) and 4 start times per program. It provides easy push-button programming for start and run times, with features like seasonal adjustments and manual overrides for flexible irrigation control.

Standard Hunter Controller Programming

The Hunter Node 100 utilizes standard Hunter controller programming, offering 3 independent programs (A, B, and C) with up to 4 start times per program. This allows for flexible scheduling of irrigation cycles, catering to different zones or watering needs. The controller features a push-button interface for easy navigation and programming, differing from traditional dial-based systems. Users can set start times and run times for each program, with the ability to adjust settings using the plus (+) or minus (-) buttons. The system also supports advanced features like manual overrides and test runs. With a user-friendly design, the Node 100 simplifies irrigation management while maintaining robust programming capabilities.

Setting Start Times and Run Times

To set start times on the Hunter Node 100, press the button until the start time icon appears, then use the plus (+) or minus (-) buttons to adjust the time. Each program (A, B, or C) can have up to four start times, allowing for flexible scheduling. For run times, select the desired station or program and adjust the duration using the same buttons. The controller allows run times to be set from one minute to several hours, depending on irrigation needs. The Node 100 also features a test function to verify programming accuracy, running each station sequentially. This ensures proper setup and operation, making it easy to customize watering schedules for optimal efficiency and coverage.

Additional Features

The Hunter Node 100 includes weather sensor compatibility to pause watering during rain, seasonal adjustments for water conservation, and manual operations for quick overrides.

Connecting a Weather Sensor

The Hunter Node 100 supports the integration of weather sensors, such as the Mini-Clik or Rain-Clik, to enhance irrigation efficiency. These sensors detect rainfall and automatically pause watering during adverse weather conditions. To connect a weather sensor, simply attach it to the Node 100’s sensor port. The sensor does not require power, as it operates passively. Once connected, the Node 100 will override its programmed schedule during rain events, preventing unnecessary water usage. This feature ensures water conservation while maintaining healthy landscaping. The sensor integration is seamless and does not interfere with other programming functions, making it a practical addition to your irrigation system.

Seasonal Adjustment and Manual Operations

The Hunter Node 100 allows for seasonal adjustments, enabling users to modify watering durations based on weather conditions. This feature adjusts irrigation run times by a percentage, optimizing water usage throughout the year. Manual operations provide flexibility, letting users activate a single station or entire program temporarily. During manual watering, the weather sensor is bypassed, ensuring irrigation occurs regardless of weather. This is ideal for maintenance or addressing dry soil. The controller returns to its programmed schedule after manual operation. Seasonal adjustments and manual overrides enhance customization, making the Node 100 adaptable to varying landscaping needs while maintaining efficient water management.

Troubleshooting and Maintenance

Troubleshooting the Hunter Node 100 involves identifying common issues like no display or incorrect watering cycles. Resetting the controller or running diagnostics can resolve many problems, ensuring optimal performance.

Troubleshooting Common Issues

Common issues with the Hunter Node 100 include no display, incorrect watering cycles, or sensor malfunctions. No display often results from low battery or faulty connections. Check battery life and ensure proper wiring. Incorrect watering cycles may occur due to multiple start times or conflicting programs. Review and adjust program settings to resolve this. Sensor issues, such as a rain sensor not stopping irrigation, can be addressed by ensuring the sensor is properly connected and configured. For advanced troubleshooting, the Node 100 offers diagnostic modes to identify solenoid or wiring faults. Regular maintenance, like cleaning the rubber cover and updating programs, helps prevent issues and ensures reliable operation. Always refer to the manual for detailed troubleshooting steps and solutions.

Resetting the Controller and Diagnostic Procedures

Resetting the Hunter Node 100 erases current program data and restarts the controller, but it does not delete programs saved to permanent memory. To reset, press the button until the icon and “Off” appear, then wait for the display to shut off. For diagnostics, the Node 100 offers a Quick Check feature to identify common issues like solenoid shorts or wiring faults. Press the button during startup to activate diagnostic mode, which tests all stations. The battery life indicator on the display helps monitor power levels. If issues persist, refer to the troubleshooting guide or reset the controller to restore default settings. This ensures optimal performance and helps resolve operational problems effectively.
