Wireless Rain-Clik™ sensors attach quickly and
easily to your controller. Wireless Rain-Clik™
features include:
• Quick Response™ unique technology that turns
off the irrigation system immediately – not after
it has accumulated a fixed amount of rain. No
calibration is required.
• Maintenance-free design provides trouble-free
operation for up to ten years. There are no
batteries to replace.
• Wireless operation up to 800 ft. (275m)
No wires are required between the rain sensor
and controller.
• 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
FEATURES ..................................................................................
irrigation will resume.
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 when temperatures drop
to 37˚F or below. When temperatures rise above
37˚F, the sensor will enable automatic watering.
• Automatic Synchronization – the Wireless
Rain-Clik™ transmitter will send wireless
signals every hour to the receiver to assure
that the sensor and receiver are continuously
synchronized.
• Lost Communication/Battery Status
Indication – the Sensor Bypass LED will flash
RED if the receiver has not received a signal
from the transmitter. This can indicate a low or
dead battery.

Using the hardware supplied, mount the
receiver to the wall next to the irrigation
controller. It is recommended that the receiver
be installed away from sources of electrical
interference and metal objects to maximize
communication range. Extend and straighten
the antenna upward. Make sure to attach
the rubber cover under the receiver when
installing the receiver in an outdoor location.
Wiring the Receiver to your Controller
Wiring the Receiver to a Hunter SRC
1. Attach the two yellow wires to the
AC terminals.
2. Attach the blue wire to the RS terminal.
3. Attach the white wire to the C terminal.
4. Attach the valve common wire to the
RS terminal.
MOUNTING THE RECEIVER....................................................

Normally Open Sensor Applications
1. A few controllers on the market require
normally open rain sensors. To attach
the receiver to this type of controller,
attach the blue and orange wire to the
sensor input.
Controllers with 24 VAC solenoids and
a booster pump
1. Locate the common wire to the solenoid
valves and the common wire to the pump
relay. If these two wires are connected to
the “common” terminal on the controller,
disconnect both of them.
2. Twist together these wires along with one
of the wires from the Wireless Rain-Clik™
and secure with a wire nut.
3. Attach the other wire from the
Wireless Rain-Clik
™
receiver to the
“common” terminal on the controller.
Note: The pump circuit output must be
24 VAC. Do not proceed if 115 VAC.

Standard 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 (Optional)
The sensor gutter
mount can be
purchased as an
optional accessory
for your Wireless
Rain-Clik™ (order
p/n SGM). 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.
MOUNTING THE TRANSMITTER ..........................................

11
Hints for mounting the transmitter
A. 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 ft (275 m).
B. To assure maximum range in
communication, mount the receiver
and transmitter away from sources of
electrical interference (i.e. control panels,
transformers, etc.) or metal objects.
Best performance is obtained when no
physical obstruction is between the
transmitter and receiver.
C. Correct placement of the Wireless
Rain/Freeze-Clik model is important for
accurate temperature sensing. The best
location would be out of direct sunlight.
D. The reset rate refers to the amount of
time it takes for the sensor to dry out
sufficiently for the sprinkler system to be
allowed to come back on. The mounting
location will affect 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.

Transmitter Operation
There is nothing to set up with the
Wireless Rain-Clik™.
Receiver Operation
The receiver has two LED lights that indicate
the state of the system.
SENSOR STATUS LED:
RED – sensor is
wet (watering
disabled)
GREEN – sensor
dry (watering
enabled)
YELLOW –
sensor is in
addressing mode
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.
ADJUSTMENTS AND OPERATION ........................................
Note: When you first apply power to the
receiver, the SENSOR STATUS LED will be
RED. Press the manual test spindle on the
transmitter for 5 seconds and release the
spindle. The SENSOR STATUS LED will turn
GREEN indicating proper operation.

13
Bypassing the Sensor
The sensor may 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.
Note: 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.

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 4 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.
Battery Life
The Wireless Rain-Clik™ transmitter is
designed to operate up to ten years with
it’s sealed, maintenance-free battery. The
transmitter is available as a replacement part.
(WRC-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.
ADJUSTMENTS AND OPERATION (continued) ...................

15
2. Within a few seconds the LED light on the
bottom of the sensor will briefly flash.
3. Release the spindle and the LED light will
flash again. If the LED flashes, the battery
in the transmitter is good.
If you are experiencing problems with your
Wireless Rain-Clik™ sensor, follow these
simple checks first before assuming the unit is
defective and replacing it.
System will not come on at all:
A. Check to make sure that the sensor discs
are dry and the switch “clicks” on and off
freely by pressing the top of the spindle.
B. Look for breaks in the wire leading to the
receiver and check all connections.
C. Verify outside air temperature
(for Rain/Freeze-Clik installations).
System will not shut off even after
heavy rainfall:
A. Remove the sensor jumper across the two
SEN terminals.
B. Check to make sure that rainfall is hitting
the sensor.
C. Look for breaks in the wire leading to the
receiver and check all connections.
D. Check the battery in the transmitter
(See page 14).
Sensor Bypass LED is ashing red:
A. Check that the battery in the transmitter
is good (See page 14).
B. Check for obstructions around the
transmitter or receiver antennae.
