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 110V 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 WiFi 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.
