Installation

Hunter HPC

Installation is ideal for:

• Larger irrigation systems

Because the controller is modular, expansion modules can be added later without replacing the controller.

Rain Bird RC2

Installation is straightforward for:

Since it has a fixed number of stations, expansion requires replacing the controller if your irrigation system grows beyond its capacity.

Smart Features

Hunter HPC

Hydrawise provides:

• Contractor access
• Email notifications
• Push alerts
• Flow monitoring
• Detailed reporting

Rain Bird RC2

The RC2 includes:

While capable, it offers fewer advanced management tools than Hydrawise.

Expandability

This is one of the biggest differences.

Hunter HPC

Starts with 4 stations and expands to 32.

Perfect if you plan to:

Rain Bird RC2

If additional zones are needed later, a larger controller may be required.

Flow Monitoring

Hunter offers one of the strongest advantages here.

With the optional HC Flow Meter you can:

• Detect leaks
• Monitor water usage
• Receive high-flow alerts
• Receive low-flow alerts
• Protect pumps

The Rain Bird RC2 does not provide the same level of integrated flow management.

Mobile Apps
