Wireless Rain-Clik Features
To prevent water waste, built-in Quick Response®
Technology instantly shuts down irrigation as soon
as it starts raining.
Key Benets
1. Quick Response: Innovative technology that turns
o the irrigation system immediately rather than
aer it has accumulated a xed amount of rain. No
calibration is required.
2. Maintenance-Free Design: Provides trouble-free
operation for at least 5 years. There are no batteries
to replace.
3. Wireless Operation Up to 800' (243 m): No wires
are required between the rain sensor and controller.
4. Wireless Rain-Clik Sensor (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 Sensor (WRF-CLIK):
The Wireless Rain/Freeze-Clik includes a freeze
sensor that is designed to keep the irrigation
system from operating when temperatures drop to
37˚F (3˚C) or below. When 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.
7. Lost Communication/Battery Status Indication: The
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.

Wireless Rain-Clik Sensor
1. Manual Test Spindle: Press and hold the manual test
spindle to conrm proper operation of your transmitter.
2. Vent Ring: Used to adjust the reset rate or dry out time
for the sensors. Opening the vents will decrease the
reset rate, while closing the vents will increase the time
it takes for the discs to dry out.
3. Radio Antenna: Transmits a wireless signal to the
receiver up to 800'(243 m). The antenna should be
oriented vertically.
4. Mounting Arm: Metal extension arm for mounting
the sensor.
5. Battery Status LED: Used to determine the status of
the sealed battery. Pushing the manual test spindle will
flash the LED light indicating that the battery is good.

Mounting the Sensor
Surface Mounting
Using the screws provided with your sensor, mount the
transmitter on any surface where it will be exposed to
unobstructed rainfall, but not in the path of sprinkler
spray. The sensor should be oriented upright (as pictured),
but the swivel bracket can be moved for mounting on
any angled surface. Loosen the locknut and screw before
swiveling the bracket, and then re-tighten.
Gutter Mounting
The SGM allows the transmitter to be mounted
directly to the edge of a gutter. Install the SGM on
the transmitter by removing the metal extension arm
supplied with your sensor and reinstalling the SGM.
Position the gutter mount on the edge of the gutter and
twist the thumbscrew to secure it in place.

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 suciently for the sprinkler
system to be allowed to come back on. The mounting
location will aect 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.

Adjustments and Operation
Bypassing the Sensor
The sensor can be bypassed by using the built-in bypass
feature on the receiver. To bypass the sensor, press the
SENSOR BYPASS button on the receiver. The bypass
status light will turn red when the sensor is bypassed.
Pressing the SENSOR BYPASS button again will re-enable
the sensor and the sensor bypass light will go out.
Setting the Transmitter Address at the Receiver
Each transmitter is produced with a unique address.
A receiver must learn this address to work with that
transmitter. This step is only necessary if transmitters and
receivers are purchased separately.
1. Prior to applying power (yellow wires) to the receiver,
press and hold the bypass button on the receiver.
2. While the bypass button is depressed, apply power to
the receiver. The sensor status indicator light should
light up yellow indicating that the receiver is ready to
learn a new address.
3. Press and hold the quick response button on the
transmitter.
4. Within four seconds, the receiver’s sensor status
indicator light should turn red. The receiver has now
learned the address and it will be retained even in the
event of a power outage.
5. Release the button on the transmitter. The sensor
status indicator light should turn green.
Units purchased as a kit will already have their
communication address preset. No addressing is
necessary. However, if the receiver or transmitter
is replaced you need to reset the address.

Adjustments and Operation
Battery Life
The Wireless Rain-Clik Transmitter is designed to operate
for at least 5 years with its sealed, maintenance-free
battery. The transmitter is available as a replacement
part (WR-CLIK-TR). Should you need to change the
transmitter, the receiver will have to learn the new
transmitter address.
To Check the Status of the Battery in the
Transmitter
1. Press and hold the quick response spindle at the top
of the sensor on the short stack.
2. Within a few seconds the LED light on the bottom
of the sensor will briey ash.
3. Release the spindle and the LED light will ash again. If
the LED ashes, the battery in the transmitter is good.
If you are experiencing problems with your Wireless
Rain-Clik Sensor, follow these simple checks rst before
assuming the unit is defective and replacing it.
System Will Not Turn On at All
• Check to make sure that the sensor discs are dry and
the switch “clicks” on and o freely by pressing the top
of the spindle.
• Look for breaks in the wire leading to the receiver and
check all connections.
• Verify outside air temperature (for Rain/Freeze-Clik
installations).
System Will Not Shut O Even Aer Heavy Rainfall
• Remove the sensor jumper across the two SEN
terminals.
• Check to make sure that rainfall is hitting the sensor.
• Look for breaks in the wire leading to the receiver
and check all connections.
• Check the battery in the transmitter.
Sensor Bypass LED Is Flashing Red
• Make sure the battery in the transmitter is good.
• Check for obstructions around the transmitter or
receiver antenna.
