Hunter RFC combines rain and freeze sensing in one wired unit to prevent unnecessary irrigation and protect landscapes. The RFC uses Quick Response technology to stop watering as soon as rain begins while its freeze sensor disables irrigation at low temperatures.

  • Instant rain shutoff: Quick Response discs detect moisture and open the sensor circuit to stop valve operation immediately, reducing water waste during the first droplets.
  • Freeze protection: Built-in freeze sensing automatically disables irrigation at 37°F (3°C) to help prevent freeze damage to plants and irrigation components.
  • Easy mounting: Install on an eave, wall, post, or with the optional gutter mount for flexible placement away from sprinkler spray.
  • Wired connection: Includes approximately 25 ft (7.6 m) of two-conductor, 20 AWG sheathed wire for straightforward hook-up to most controllers.
  • Adjustable reset: Vent ring lets you set the drying/reset rate so the sensor returns to active watering on your schedule.
  • Durable construction: Rugged polycarbonate housing with metal extension arm resists weather and provides long service life.

Compatible with most automatic irrigation controllers that accept sensor input (normally open or normally closed). The Hunter RFC is a simple, reliable solution for conserving water, preventing unnecessary run time during rain, and avoiding freeze damage in colder conditions.
