Weathermatic ProLine controllers deliver professional irrigation control for small to medium landscapes. The PL800 (indoor) and PL1600 (outdoor) platforms are modular, easy to program, and include diagnostic tools that simplify installation and reduce downtime.

• Modular expansion: 4‑station base that supports hot‑swappable expansion modules to increase zone capacity without replacing the controller.
• Built‑in valve locator: Quickly identify and troubleshoot valves at the controller using the integrated locator function.
• Real‑time milliamp display: Monitor solenoid current for fast fault detection and reliable diagnostics.
• Flexible scheduling: Zone run times set from 1 minute to 9 hours 55 minutes, plus run/soak cycles, omit days, and custom watering patterns (odd/even or interval days).
• Advanced program control: Seasonal percentage adjustment by program and by month, two independently programmed master valves, and programmable zone‑to‑zone delays.
• Sensors & reliability: Rain/freeze sensing and rain delay options help prevent unnecessary watering; fault review displays open/shorted zones for quick service.

Each ProLine model ships with comprehensive documentation (installation instructions, quick start and owner’s manual) and is designed for irrigation professionals and informed homeowners who need dependable, serviceable controllers.
