Protect landscape, walkways, and roadways from ice with the Hunter FREEZE-CLIK wired freeze sensor. Preset to stop irrigation at freezing temperatures, the Freeze-Clik automatically prevents scheduled watering during cold events and restores normal operation when temperatures rise. The compact, weather-resistant housing mounts quickly and wires directly to the controller for reliable, low-maintenance protection.

  • Automatic freeze protection: Factory-set to interrupt irrigation at approximately 37°F (3°C) to eliminate ice formation on turf and hardscapes.
  • Durable, prewired design: Includes 25' of 20 AWG UL-approved, two-conductor sheathed wire for straightforward installation.
  • Controller compatibility: Works with a wide range of Hunter controllers and most standard irrigation controllers using a common ground or sensor terminal.
  • Electrical rating & approvals: Designed for 24 VAC operation with a 5 A switch rating; approvals include UL, cUL, FCC, CE, and RCM for global use.
  • Reliable warranty: Backed by a 5-year Hunter warranty for long-term dependability.
  • No adjustments needed: Factory calibrated with a ±2°C tolerance; installs quickly and operates without user calibration.

Freeze-Clik pairs easily with other Clik sensors to create a comprehensive weather-sensing strategy. For wiring, connect one lead to the controller common and the other to the sensor input or common ground of the valves; if a rain sensor is present, wire in series so either device can interrupt irrigation. See the included installation card and product literature for wiring diagrams, controller-specific notes, and CAD details.
