Adjustments and Operation
Tips for Mounting the Sensor
•  Choose a location such as the side of a building or post. 
The closer the transmitter is to the receiver, the better 
the reception. Do not exceed 800' (243 m).
•  To ensure maximum range in communication, mount 
the receiver and transmitter away from sources 
of electrical interference (e.g., control panels, 
transformers, etc.) or metal objects. Best performance 
is obtained when no physical obstruction is between 
the transmitter and receiver.
•  Correct placement of the Wireless Rain/Freeze-Clik 
model is important for accurate temperature sensing. 
The best location would be out of direct sunlight.
•  The reset rate refers to the amount of time it takes 
for the sensor to dry out suciently for the sprinkler 
system to be allowed to come back on. The mounting 
location will aect this rate. For example, mounting 
the transmitter in a very sunny location may cause 
the sensor to dry out sooner than desired. Similarly, 
mounting the sensor in constant shade may keep the 
sensor from drying out sooner.
Receiver Operation
The receiver has two LED lights that  
indicate the state of the system.
1.  SENSOR STATUS LED:  
RED – Sensor is wet  
(watering disabled).  
GREEN – Sensor is dry 
(watering enabled). 
YELLOW – Sensor is in 
addressing mode.
2.  SENSOR BYPASS LED: 
RED – Rain sensor is bypassed (even though the sensor 
is bypassed, the STATUS LED will continue to alert you 
of the state of the sensor — wet or dry). 
OFF – Rain sensor is enabled. 
FLASHING RED – Indicates that communication 
between the transmitter and receiver was lost.
When you rst apply power to the receiver, the 
SENSOR STATUS LED will be RED. Press the 
manual test spindle on the transmitter for ve 
seconds and release the spindle. The SENSOR 
STATUS LED will turn GREEN indicating 
proper operation.
