Installation and physical design
The unit is designed to be installed outdoors and withstand the elements, which makes life easier if you prefer not to run a long conduit into a garage or shed. The enclosure is sturdy and the 2.75-inch touchscreen is readable in most lighting conditions, which simplifies manual operation and on-site adjustments.
Outdoor housing and durability
The weather-resistant housing protects the electronics from rain, dust, and temperature changes so you don’t need to worry about moving it indoors. The sealing is solid but you should still mount it under a small overhang if you live in an area with extreme weather for extra protection.
Wiring and electrical connections
Wiring follows standard irrigation controller practices, with easy-to-access screw terminals for all 24 stations, common, and the P/MV output for a master valve or pump relay. The integrated milliamp sensing improves safety by detecting wire issues, which can save you time tracking down shorts or open circuits.
Mounting and physical setup
Mounting holes are pre-cut for quick installation on a flat surface like an exterior wall or sturdy fence post, and the included hardware is sufficient for most typical installations. You’ll want to plan where to place the controller relative to valve manifolds and sensors to keep wiring runs tidy and protected.
Setting up the Hydrawise app and web portal
You’ll use the Hydrawise app or the web portal to manage schedules, view alerts, and check water usage from anywhere that has internet. Account creation is simple, and the interface is focused on getting your zones online and automated quickly.
Account creation and device linking
Create an account in the Hydrawise app or on the Hydrawise website and follow on-screen prompts to add your Pro-HC controller to your account. Linking is straightforward: the controller’s WiFi setup guides you through connecting to your network so the portal can reliably push and pull schedule and sensor data.
WiFi connection and reliability
The unit connects to your home WiFi to get local weather data and deliver remote control features, but it requires a reliable WiFi signal at the installation location. If signal strength is weak outdoors, consider a WiFi extender or running ethernet to a nearby building and mounting the controller there for a more stable connection.
Adding zones and labeling
You’ll add each of your 24 zones to Hydrawise and assign names, plant types, and irrigation details so the system can manage run times intelligently. Taking a few extra minutes to label zones clearly—like “front lawn east” or “back flower beds”—pays off when you want to make quick changes from your phone.
Scheduling through the app and web portal
You set programs and start times in the app or web portal, and the system applies weather adjustments automatically if you enable that feature. Manual starts and station testing are also handled easily through the interface so you can troubleshoot on the spot without flipping through the physical menus.
Programming flexibility and scheduling options
The controller gives you six independent programs and up to six start times per program, so you can tailor irrigation to very specific watering needs across diverse landscapes. This level of flexibility lets you schedule turf, shrub areas, and drip zones differently so each receives the proper amount of water.
6 independent programs and start times
Each program can be configured with its own days and start times, which is especially helpful when you need multiple watering windows for park-like lawns and separate schedules for trees or greenhouses. You can sequence start times to avoid electrical or water pressure overload when many valves run simultaneously.
Station-based scheduling for precision
Station-based scheduling means you can program run durations per station instead of lumping sections together, which optimizes water use and reduces runoff. This is particularly effective for properties that have mixed irrigation types—spray heads, rotors, and drip lines—that require different run times.
Manual control and touchscreen convenience
The full-color touchscreen streamlines manual starts, zone tests, and on-controller adjustments without having to use an app. If you prefer hands-on tweaks, you’ll appreciate the responsive interface and clear status indicators for each station.
Smart weather-based watering and water savings
Weather-based adjustments are the main reason you’ll likely buy a smart controller: the Pro-HC pulls local weather to automatically alter schedules so you’re not irrigating during rainy, cool, or windy periods. Over time, these adjustments can significantly reduce water usage and lower your water bills while preserving landscape health.
How the controller determines weather
Hydrawise uses a combination of your controller’s GPS location, nearby weather stations, and forecasts to calculate evaporation and precipitation adjustments for your schedule. These inputs let the system recommend or automatically set run times that match current and predicted conditions rather than fixed calendar days.
What triggers an automatic adjustment
Rainfall, humidity, temperature changes, and wind are all factors that can trigger the controller to shorten, skip, or delay watering events. You can fine-tune the sensitivity of these adjustments so that the system aligns with your watering philosophy—aggressive conservation or conservative plant care.
Expected water savings and real results
Most users see measurable reductions in monthly water usage because the controller eliminates unnecessary watering and optimizes run times by zone. The degree of savings depends on your previous manual practices, landscape composition, and local climate, but the combination of weather intelligence and station-specific control tends to deliver meaningful results.
Flow monitoring and wire fault detection
Protecting your irrigation system is just as important as saving water, and this Pro-HC model provides robust protections to help you catch problems early. Integrated milliamp sensing monitors the wiring for issues and optional flow meter compatibility gives you leak detection—two features that can prevent big repairs.
Milliamp sensing for wire faults
Milliamp sensing watches the electrical current in each station circuit and alerts you if a wire is shorted or opened, which can point to a damaged solenoid, rodent-chewed cable, or poor connection. You’ll get an alert in the app and the controller will flag the specific zone so you can fix the problem quickly instead of chasing intermittent failures.
Flow meter compatibility and leak detection
When you add an HC Flow Meter, the Hydrawise system monitors actual water flow and compares it to expected values for each irrigation event. A spike or drop in flow triggers alerts for leaks, broken pipes, or stuck valves, helping you avoid wasted water and costly property damage.
Benefits of early detection
Early detection reduces the chance of unseen leaks causing soil erosion, foundation problems, or steep water bills. You’ll appreciate receiving actionable alerts with specific locations and recommended checks so you can address issues before they become expensive.
