Zurn Weathermatic SLW5 Wireless Weather Station (SmartLine) - SLW5

Weathermatic SLW5 Wireless Weather Station delivers on-site weather sensing and SmartLine compatibility to automatically adjust irrigation run times based on real-time conditions. Designed for outdoor use, the SLW5 combines rain and freeze detection with evapotranspiration (ET)-based adjustments to reduce water waste and lower operating costs for residential and light-commercial systems.

Durable and easy to install, the SLW5 is ideal for contractors and landscape professionals who want reliable, low-maintenance weather-based irrigation control. Refer to the included installation guide for setup steps, diagnostics, and warranty information.

Features
  • SmartLine compatible — ships with the SLHUB‑RF‑5 wireless hub for easy setup and pre-paired communication.
  • Adjustable rain shut-off from 1/8″ to 1″ (3–25 mm) with an extended rain-delay feature (48‑hour default; adjustable 0–99 hours).
  • Freeze shut-off activates at 37°F (3.0°C) and automatically resumes irrigation when temperatures rise.
  • 900 MHz bi‑directional wireless communication with up to 1,500 ft (457 m) line-of-sight range; obstacles may reduce effective range.
  • Operates on two AAA lithium batteries (supplied) with remote battery diagnostics and up to 10-year battery life under normal conditions.
  • Protective white solar shields and an adjustable aluminum mounting arm for gutter or wall installation provide accurate temperature readings and low maintenance.
  • On-board diagnostics report battery and communication status to the SmartLine controller to simplify troubleshooting.
What our Experts Think
  • ET-based irrigation control: Feeds live weather data to SmartLine controllers to automatically adjust watering schedules and reduce water waste.
  • Wireless long-range communication: 900 MHz bi-directional signal with up to ~1,500 ft line-of-sight range for flexible installation.
  • Rain & freeze protection automation: Automatically halts irrigation during rainfall or when temperatures drop to ~37°F (3°C).
  • Smart water savings logic: Continuously adjusts irrigation run times based on evapotranspiration (ET) and local weather conditions.
  • Low-maintenance design: Protective solar shielding improves temperature accuracy while minimizing cleaning needs.
  • Installer-friendly setup: Pre-paired wireless hub system simplifies installation and reduces commissioning time.
  • Commercial-grade reliability: Built for professional irrigation systems where efficiency, compliance, and automation matter.

Q&A

Q: What is the Zurn Weathermatic SLW5 used for?
A: A wireless on-site weather station that connects to SmartLine® irrigation controllers to automatically adjust watering based on real-time weather conditions.

Q: How does it improve irrigation efficiency?
A: It uses evapotranspiration (ET), rainfall, and temperature data to automatically increase or reduce watering schedules, helping prevent overwatering and water waste.

Q: Is it compatible with irrigation controllers?
A: Yes. It is designed specifically for Weathermatic SmartLine® controllers and communicates wirelessly via a 900 MHz system.

Q: What weather conditions does it monitor?
A: It tracks rainfall, temperature, and freeze conditions, and can pause irrigation during rain or when temperatures drop near freezing (around 37°F / 3°C).

Q: What is its wireless range?
A: Up to approximately 1,500 ft line-of-sight between the weather station and controller hub.

Q: Does it require wiring?
A: No. It is fully wireless and powered by long-life lithium batteries for low-maintenance operation.

Q: Where is it typically installed?
A: Outdoors on a wall, pole, or gutter with open exposure to rainfall and airflow for accurate readings.


Maintenance Tips
  • Clean rain sensor tipping bucket and debris screen regularly to ensure accurate rainfall readings.
  • Inspect solar panel (if equipped) and battery compartment for dirt, corrosion, or moisture intrusion.
  • Verify wireless signal strength and station connectivity to the irrigation controller periodically.
  • Check mounting hardware for loose fittings or weather damage, especially after storms or high winds.
  • Replace batteries as recommended to maintain continuous data transmission and accuracy.
  • Keep firmware/controller settings updated for optimal SmartLine system performance.
  • Perform seasonal checks to ensure accurate rain, temperature, and wind data calibration.
