Brand: Hunter Industries SKU: WRFCLIK
Product Overview
The Hunter WRF-CLIK is a wireless Rain/Freeze-Clik system that includes an outdoor rain-and-freeze transmitter plus a controller-mounted receiver. It is designed to interrupt automatic irrigation when rainfall begins and to keep the system from operating at or below approximately 37°F. The wireless connection eliminates the need to route a sensor cable from the outdoor mounting point back to the irrigation controller.
Hunter’s current installation instructions recommend locating the transmitter within approximately 200 feet of the receiver with the clearest practical signal path. Complete kits are factory paired, while replacement components can be re-addressed in the field. The receiver provides wet/dry status indicators and a bypass button for supported installations.
The sealed transmitter uses a maintenance-free battery designed for up to approximately five years of daily operation. Quick Response technology can stop irrigation within about two to five minutes after rainfall begins. The rain-sensing portion resumes normal operation as the moisture-responsive components dry, while the freeze function is preset and does not require adjustment.

Compatibility and Installation Notes
- The receiver is designed for compatible 24 VAC irrigation-controller circuits only.
- Mount the sensor where it receives natural rainfall but not sprinkler spray.
- For accurate freeze sensing, position the transmitter out of direct sunlight with free outdoor airflow.
- Keep the sensor within approximately 200 feet of the receiver and test the signal before permanent mounting.
- Metal structures, walls, electrical equipment, and site conditions can reduce wireless range.
- The freeze function supplements, but does not replace, visual checks and responsible winter irrigation management.
