For many years, Hunter has offered two similar styles of Wireless Rain-Clik Sensors: the WR-CLIK (rain sensor only) and the WRF-CLIK (rain and freeze sensor). While both options remain popular in many markets, Hunter has decided to consolidate them into one high-performing solution.
WR-CLIK and WR-CLIK-TR models with manufacturing date codes of NOV 22 and newer have the rain and freeze sensors included. The addition of the freeze sensor was only implemented in Wireless Rain-Cliks. Wired Rain-Clik models have not been updated, and Hunter continues to offer the wired rain/freeze sensor (model: RFC).
