The Rain Bird WR2-RFC wireless Rain/Freeze Combo sensor provides automatic rain and low-temperature shutoff for 24 VAC irrigation controllers. Its intuitive icon-driven interface and enhanced antenna array deliver reliable signal performance to reduce wasted water and protect landscapes while simplifying installation and programming. Automatic rain and freeze shutoff: Stops irrigation during measurable rainfall and when temperature drops below your set point to prevent overwatering and freeze damage. Adjustable thresholds: Set rainfall sensitivity from approximately 3–13 mm (1/8"–1/2") and low-temperature limits from 0.5–5 °C (33–41 °F) for precise control. Reliable wireless range: Enhanced antenna array supports clear transmission up to about 90 m line-of-sight to the controller for flexible sensor placement. Simple installation: Self-leveling mounting bracket fits gutters or flat surfaces and the interface includes a 76 cm cable for easy 24 VAC controller connection. Durable construction: UV-stable, high-strength polymer housing with 6 kV surge protection stands up to harsh outdoor conditions. Long-life battery: User-replaceable battery provides multiple years of operation under normal conditions; replacement is tool-free. Controller compatibility: Works with most 24 VAC irrigation controllers (note: not compatible with ESP-SMT/SMTe and select SST controllers). Designed for professionals and homeowners who want dependable automatic weather response, the WR2-RFC combines precision sensing, easy setup, and proven Rain Bird reliability. Use the adjustable settings to balance landscape health and water savings—typical installations report up to 35% water savings when sensors are correctly applied.
