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. When the freeze sensor 
option switch is activated the sensor interrupt s watering when the temperature 
drops on or below 37°F ± 2° (3°c ± 1°).

please read this manual completely before you install and use the sensor.

A Few of the Notable Design Features Include:

RF Communication

rF (radio Frequency) technology eliminates unsightly wires and  
simplifies mounting.

Battery Power

the rain/freeze sensor is powered by two replaceable 3V lithium batteries.

Feature Control Switch

Located on the bottom of the transmitter, the 3-position control switch allows 
you to select rain sensor, rain/Freeze sensor and sensor off.
