operation for up to 10 years. There are no batteries to 
replace. 
3.  Wireless Operation Up to 800' (275 m)
 – No wires are 
required between the rain sensor and controller. 
4.  Two models available: Wireless Rain-Clik (WR-CLIK) 
– Acts as a switch to deactivate automatic watering 
of your irrigation controller when it rains. Once rain 
has stopped and the sensor has dried out, automatic 
irrigation will resume.
5.  Wireless Rain/Freeze-Clik (WRF-CLIK) – The Wireless 
Rain/Freeze-Clik includes a freeze sensor that is 
designed to keep the irrigation system from operating

temperatures rise above this temperature, the sensor 
will enable automatic watering.
6.  Automatic Synchronization – The Wireless Rain-Clik 
transmitter will send wireless signals every hour to 
the receiver to ensure that the sensor and receiver are 
continuously synchronized.

Sensor Bypass LED will ash RED if the receiver has not 
received a signal from the transmitter. This can indicate 
a low or dead battery.
