Hunter NODE-200 - battery operated control unit

Product detailed description

The Hunter NODE-200 is a compact control unit intended for use in small to medium-sized irrigation systems where a local control point is required. It is commonly used in residential gardens, small commercial properties, and in irrigation shafts where space is limited. The unit is designed to operate independently, without the need for a central controller, making it ideal for remote or decentralised irrigation setups. Installers typically use it in systems where two distinct irrigation zones need to be controlled separately, such as front and back gardens or separate flower beds. The unit is battery operated, which eliminates the need for electrical wiring and makes it suitable for locations without access to a power supply.

Its compact size and weather-resistant housing allow for installation in exposed outdoor environments or within irrigation shafts. The NODE-200 is particularly useful in retrofit projects where adding a new central controller is not feasible. It is also suitable for use in systems where a secondary control point is needed for redundancy or local control. The unit is programmed manually, which makes it accessible for installers who prefer direct control over automated settings.

The technical parameters of the Hunter NODE-200 are primarily defined by its battery operation and its ability to manage two separate irrigation sections. The unit does not require an external power supply, which simplifies installation and reduces dependency on electrical infrastructure. The number of sections it can manage is fixed at two, which is suitable for small systems or for use as a supplementary controller in larger systems. The operating range is not specified in the technical data, but the unit is designed for direct installation in the field or in an irrigation shaft, indicating a short-range control capability. The battery life and programming options are not included in the provided data, so further details should be obtained from the manufacturer’s technical documentation.

Installation and connection

The Hunter NODE-200 is designed for straightforward installation in an outdoor environment or within an irrigation shaft. It should be mounted in a location that is accessible for programming and inspection but protected from direct exposure to water or extreme weather conditions. The unit connects to two irrigation zones via standard solenoid valves, and the wiring should be checked for correct polarity and continuity before activation. Installers should ensure that the battery compartment is securely closed to prevent water ingress and that the programming settings are verified before commissioning. Common installation mistakes include incorrect wiring of the solenoid valves, failure to secure the unit against environmental exposure, and incorrect programming of the control sequence. It is also important to ensure that the battery is correctly installed and that the unit is not placed in a location where it could be damaged by irrigation water or foot traffic.

Compatibility and accessories

The Hunter NODE-200 is compatible with standard solenoid valves used in irrigation systems. It is intended for use with two separate zones and is not designed for integration with larger central control systems. Accessories such as batteries and mounting brackets may need to be ordered separately, depending on the installation requirements. No related products are listed in the provided information, so installers should verify the availability of additional components such as protective enclosures or extension cables if needed for the specific installation site.

Technical background for designers

The Hunter NODE-200 operates on a battery-powered control system that activates solenoid valves in two separate irrigation zones. The unit is constructed with a durable housing to withstand outdoor conditions and is designed for low-maintenance operation. The control logic is based on manual programming, which allows for precise control over the timing and sequence of zone activation. The unit’s performance and service life depend on the quality of the battery, the integrity of the wiring connections, and the environmental conditions at the installation site. Proper installation in a dry, stable location will help to maximise the unit’s efficiency and longevity.

Service and operation

The Hunter NODE-200 requires minimal maintenance due to its simple design and battery operation. Regular checks should be performed to ensure that the battery is functioning correctly and that the wiring connections remain secure. The unit should be inspected for signs of water ingress or physical damage, especially in exposed installations. If the unit fails to activate the solenoid valves, the wiring should be checked for continuity and correct polarity. No specific service intervals are provided in the technical data, so maintenance should be carried out as needed based on the observed performance and environmental conditions.

Frequently asked questions

Can the Hunter NODE-200 be used in a system with more than two irrigation zones?
No, the unit is designed specifically for two zones. Additional units may be required for larger systems.

Is the Hunter NODE-200 compatible with all types of solenoid valves?
The unit is compatible with standard solenoid valves used in irrigation systems. Specific compatibility should be verified based on the valve specifications.

Can the Hunter NODE-200 be installed in an irrigation shaft?
Yes, the unit is designed for installation in irrigation shafts or directly in the field, provided that it is protected from water ingress.

Does the Hunter NODE-200 require a power supply?
No, the unit is battery operated and does not require an external power supply for operation.
