Are you looking to upgrade your Hunter Pro-C irrigation controller with WiFi capabilities? You have two excellent options: the Hydrawise HPC-FP or the Centralus PC-WIFI module. Both bring smart irrigation technology to your existing system, but they offer different features, user interfaces, and pricing structures. Let’s compare them to help you make the best choice for your needs.
The Hunter Pro-C Controller
Before diving into the WiFi upgrade options, it’s worth noting that the Hunter Pro-C is one of the most popular irrigation controllers on the market. Hunter has produced several generations of Pro-C controllers over the years, with different compatibility for WiFi upgrades.
How to Identify Your Pro-C Controller Model
To determine which WiFi upgrade option is right for your controller, you need to identify your specific Pro-C model:
- PC-300 vs. PC-400: The older PC-300 models (typically with green buttons) were discontinued in 2014 and replaced with the PC-400 models (with blue buttons and a Solar Sync dial position).
- Date Code: Look for the manufacturing date code on the white sticker inside the wiring compartment of your controller. Pro-C controllers manufactured since March 2014 are compatible with both WiFi upgrade options.
- Physical Appearance: PC-400 models have blue buttons and a dedicated Solar Sync dial position, while older PC-300 models have green buttons and no Solar Sync position on the dial.
- Ribbon Cable: PC-400 models have a ribbon cable with two rows of pins, while older models use a single row of pins.
*PC-300 models are not compatible with the HPC-FP facepack or the PC-WIFI module.
If you have a Pro-C model #10032800 manufactured in December 2023, you have a newer PC-400/P2C-400 model that is compatible with both the Hydrawise HPC-FP and the Centralus PC-WIFI upgrade options. Since your controller was manufactured well after the March 2014 cutoff date, you can choose either WiFi option based on your feature preferences rather than compatibility concerns.

Installation process:
- Turn off power to the controller
- Remove the ribbon cable from the current front panel
- Replace with the Hydrawise HPC-FP panel
- Reconnect the ribbon cable
- Restore power and configure WiFi settings
Centralus PC-WIFI
The PC-WIFI is an add-on module that connects to your existing Pro-C controller. This allows you to maintain the original controller interface while adding WiFi capabilities.
Installation process:
- Turn off power to the controller
- Install the PC-WIFI module inside the controller cabinet
- Connect necessary wiring
- Restore power and configure WiFi settings through the Centralus web platform
Answering Customer Questions
For Hunter Pro-C Model #10032800 (December 2023 Manufacture)
For the customer with a Hunter Pro-C model #10032800 manufactured in December 2023: Your controller is a newer P2C-400 model that is compatible with both WiFi upgrade options. Here’s what you should consider:
- If you prefer a dedicated mobile app, touchscreen interface, and advanced weather-based watering features, choose the Hydrawise HPC-FP front panel replacement.
- If you prefer maintaining your current controller interface and only need web-based remote access, choose the PC-WIFI module with Centralus.
Both options will work with your controller since it was manufactured well after the March 2014 compatibility cutoff date. Your decision should be based on your desired features and interface preferences rather than compatibility concerns.
Making the Right Choice
When deciding between Hydrawise and Centralus, consider these additional factors:
- User Experience: Hydrawise offers a more consumer-friendly experience with its mobile app and touchscreen interface. Centralus has a more utilitarian approach with its web-only interface.
- Retention of Existing Interface: If you or your landscape crews are already familiar with the Pro-C interface, the Centralus PC-WIFI lets you maintain that experience while adding remote capabilities.
- Future Expansion: Hydrawise offers more potential for expansion with its premium subscription options and ecosystem of compatible devices.
- Cost Considerations: While both systems offer free basic plans, evaluate if the additional features in the Hydrawise Enthusiast Plan ($60/year) would benefit your specific irrigation needs.
- WiFi Signal Strength: Both systems require a strong WiFi signal at the controller location. Be sure to check signal strength before installation.
Your Upgrade Options
Both the Hydrawise HPC-FP and Centralus PC-WIFI offer excellent ways to upgrade your Hunter Pro-C controller with smart irrigation capabilities. Your choice ultimately depends on your preferences for user interface, feature set, and pricing structure.
Hydrawise offers a more comprehensive, app-driven experience with advanced features and optional premium plans. Centralus provides a simpler, browser-based approach with no subscription fees for standard WiFi connections.
Whichever option you choose, upgrading your irrigation controller with WiFi capabilities will give you more control, potentially save water, and help maintain a healthier landscape. For specific installation procedures or additional compatibility questions, consult your local Hunter irrigation distributor or professional installer.
