Hunter RFC Wired Rain and Freeze Sensor

The Hunter RFC is designed to be compatible with most standard irrigation controllers on the market. As long as your controller has a sensor input terminal, this wired unit should integrate seamlessly.

Thanks to Hunter's Quick Response technology, the sensor is designed to shut off your irrigation system within minutes of detecting rain. This prevents unnecessary watering during a storm, saving both water and money.

Yes. The sensor features an adjustable vent ring that allows you to control the reset period. By opening or closing the vents, you can customize how quickly the sensor dries out and signals your controller to resume the watering schedule.

No, this is a hardwired unit that draws power directly from your irrigation controller. It does not require batteries or an external power outlet.

The sensor is factory-calibrated to trigger a shutoff at 3°C (approximately 37°F). This helps protect your irrigation pipes and sprinkler heads from potential damage caused by freezing temperatures.

The kit is versatile and includes hardware for three common mounting scenarios: flat vertical surfaces, eaves, and gutters. This allows you to place the sensor in an open area where it can accurately detect rainfall without obstruction.
