Choosing the wrong irrigation controller can create frustration later, especially when a landscape grows or irrigation needs change. Some homeowners end up replacing an entire controller simply because they ran out of available zones, while others pay for expansion flexibility they may never actually use.

That's why two of Hunter's most popular Hydrawise® compatible smart irrigation controllers, the Hunter Pro-HC and Hunter HPC, are often compared side by side.

Both controllers provide weather based irrigation adjustments, remote access and Hydrawise® smart irrigation management. Both are also designed to help homeowners reduce water waste while simplifying irrigation control.

At first glance, the controllers look fairly similar.

The biggest difference comes down to flexibility and expansion.

If you're trying to decide between the Hunter Pro-HC and Hunter HPC, understanding how each controller is designed can help determine which option fits your irrigation system best. If you're still weighing whether to upgrade from a traditional timer at all, start with our guide on smart irrigation vs traditional timers.

What the Pro-HC and HPC Have in Common

Both controllers are fully Hydrawise® enabled and offer many of the same smart irrigation features.

That includes:

• Hydrawise® cloud based irrigation management
• Remote control through the mobile app or browser
• Predictive Watering™ weather adjustments
• Full color touchscreen programming
• Flow monitoring compatibility
• Fault detection and alerts

Both controllers are also EPA WaterSense approved, helping homeowners improve irrigation efficiency and reduce unnecessary water usage.

For many residential properties, either controller can provide a major upgrade over older traditional sprinkler timers.

Hunter Pro HC Overview

The Hunter Pro-HC is designed primarily for residential irrigation systems that already have a fairly defined number of zones.

It comes in fixed station models including:

• 6 station
• 12 station
• 24 station

Because the station count is fixed, homeowners simply choose the controller size that best matches their existing irrigation system.

The Pro-HC is often popular because it combines advanced smart irrigation features with a relatively simple setup process and a lower overall entry cost compared to more expandable systems.

For example, a homeowner with an established eight zone irrigation system and no major landscape renovation plans may find the Pro-HC to be the simplest and most cost effective long term solution.

Key Pro-HC features include:

• Built in Hydrawise® Wi-Fi connectivity
• Predictive Watering™ adjustments
• Touchscreen interface
• Built in milliamp sensing for diagnostics
• Optional HC Flow Meter compatibility
• Wireless Rain Clik® sensor compatibility

For homeowners with smaller to mid sized residential irrigation systems, the Pro-HC offers a straightforward smart irrigation upgrade without requiring modular expansion.

Hunter HPC Overview

The Hunter HPC offers many of the same smart irrigation capabilities as the Pro-HC but adds modular expansion flexibility.

Instead of fixed station counts, the HPC uses PCM expansion modules, allowing the controller to scale from 4 up to 23 stations.

That flexibility makes the HPC especially useful for:

• Larger residential properties
• Properties expected to add irrigation zones later
• More complex irrigation systems
• Landscapes with future expansion plans

For example, a homeowner planning a future pool installation, backyard remodel, outdoor kitchen, or additional planting beds may benefit from the HPC's ability to expand without replacing the controller later.

While the HPC may cost slightly more upfront depending on the configuration, that modular flexibility can help avoid future replacement costs if the irrigation system grows over time.

Key HPC features include:

• Hydrawise® remote irrigation management
• Modular station expansion from 4 to 23 zones
• Predictive Watering™ weather adjustments
• Built in milliamp diagnostics
• Touchscreen programming
• Pump and master valve support
• Compatibility with Hunter remotes, sensors, and HC Flow Meters

The HPC is often a strong fit for homeowners who want more long term flexibility as their landscape changes.

Which Controller Is Easier to Expand?

The HPC is clearly the more expandable option.

With the Pro-HC, the station count is fixed at the time of purchase. If your system grows beyond the controller capacity later, upgrading may require replacing the controller.

The HPC allows homeowners to add additional zones later by installing expansion modules.

That can be especially helpful for:

• Landscape remodels
• Pool additions
• New planting beds
• Outdoor living expansions
• Future irrigation projects

For homeowners in mild climates where irrigation runs year-round, the ability to expand without replacing the controller is especially valuable as landscapes evolve. See our winter irrigation tips for more on managing year-round irrigation efficiently.

Which Controller Is Better for Simpler Residential Systems?

For many standard residential properties, the Pro-HC is often the simpler choice.

If your irrigation system already has a stable number of zones and you don't expect major expansion later, the Pro-HC delivers nearly all the same Hydrawise® smart irrigation functionality in a straightforward package.

Many homeowners simply prefer the simplicity of selecting the station count they need and getting started.

Is There a Difference in Smart Irrigation Performance?

In terms of Hydrawise® smart irrigation functionality, both controllers perform extremely well.

Both support:

• Automatic weather adjustments
• Remote irrigation management
• Flow monitoring compatibility
• Smart alerts and notifications
• Predictive Watering™ scheduling

The decision usually comes down more to system size, flexibility, and future expansion rather than smart irrigation capability itself.

Pro-HC vs HPC: At a Glance

Which Hunter Smart Controller Is Right for You?

The Hunter Pro-HC is often a great choice for homeowners who:

• Want a straightforward residential smart irrigation controller
• Have a fixed number of irrigation zones
• Prefer simple installation and setup
• Don't expect significant future system expansion

The Hunter HPC is often better suited for homeowners who:

• Need modular expansion flexibility
• Manage larger or growing landscapes
• Expect future irrigation additions
• Want long term scalability

Both controllers provide powerful Hydrawise® smart irrigation management designed to improve efficiency, reduce water waste, and simplify irrigation control.

Upgrade to Smarter Irrigation Control

Whether you choose the Pro-HC or HPC, upgrading to a Hydrawise® enabled controller is one of the most impactful changes you can make to an existing irrigation system. Automatic weather adjustments, remote access, and smart monitoring replace the guesswork of fixed schedule timers, helping homeowners avoid overwatering, reduce water waste, and better understand how their irrigation system actually performs.

If you're also dealing with uneven coverage or dry patches, a smarter controller is often the first step toward diagnosing the root cause. See our guide to fixing uneven lawn watering for more on what to look for once your system is upgraded.

For many homeowners, the right controller isn't just about convenience. It's about building an irrigation system that can adapt with the landscape for years to come while improving efficiency every season.
