Hunter Industries has been building irrigation systems for over 40 years. The XC-400 is their entry-level controller, but it punches above its weight with one smart trick: Solar Sync compatibility. Plug in Hunter’s optional ET sensor, and this basic box becomes a weather-responsive smart controller. It automatically adjusts watering times based on local heat and rainfall. That means you stop overwatering after a storm or underwatering during a heatwave without touching the dial.

The XC-400 handles up to 4 stations (the Amazon copy says 8, but the model number confirms 4). That’s enough for a typical small to medium yard with separate zones for lawn, beds, and a vegetable patch. You get three independent programs, each with four start times, giving you real flexibility for different plant types. The interface is a simple dial and buttons. It’s not flashy, but it’s intuitive. You’ll set it up in under ten minutes without the manual. The unit weighs just one pound and mounts easily on a wall or post. It runs on a single included lithium battery to retain settings during power outages.

The trade-off is straightforward: this is a plastic, no-frills controller. The screen is small and not backlit, so programming at dusk is a squint. You also need to buy the Solar Sync sensor separately to unlock the smart features. If you want Wi-Fi control or a sleek app, look elsewhere. But if you want reliable, set-and-forget watering that actually responds to the weather, the XC-400 delivers solid performance at a fair price.
