Section In trod uc tIo n thank you for selecting a hydro-rain Wireless rain/Freeze sensor ® (hrc-100-rs-rF). this hydro-rain sensor provides conservation, ® convenience, and flexibility to your fully automatic watering system. After a set amount of rain has fallen, the sensor will send a wireless signal to the receiver and prevent the timer from watering. - Page 4 Section In trod uc tIo n 1. Manual Test Stem pushing downward on stem tests transmitter communication with the receiver. 2. Rain Fall Adjustment Cap range adjusts from ¹⁄ " to 1" (3mm to 25mm). this setting will prevent watering when rainfall reaches the specified setting.
