The K-Rain PRO-EX3 Modular Irrigation Controller is a next-generation solution designed for maximum flexibility, scalability, and smart irrigation control. Featuring a pre-installed 4-station module and 220V pre-wired configuration, the PRO-EX3 is ideal for both residential and light commercial applications.

Built with a hybrid design, the PRO-EX3 supports both traditional modular wiring and advanced 2-wire decoder technology—allowing systems to expand up to 40 stations. This gives contractors and property managers the ability to grow irrigation systems without replacing the controller.

With optional Wi-Fi connectivity using the K-Rain BRIDGE module, users can access, monitor, and adjust irrigation schedules remotely through the K-Rain app. Smart features like Adaptive Irrigation Mode (AIM) optimize watering schedules based on environmental conditions, helping conserve water while maintaining healthy landscapes.

The PRO-EX3 is engineered for efficiency and ease of use, featuring a full program display, intuitive interface, and advanced diagnostics. Built-in capabilities such as FlowLogic™ monitoring, a diagnostic circuit breaker, and a buried valve locator streamline installation, troubleshooting, and long-term system management.
