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 1,000 ft.

No wires are required between the rain

sensor and controller.

• Two models available:

Wireless Rain-Clik (WRC) acts as a switch

to deactivate automatic watering of your

irrigation controller when it rains. Once

rain has stopped and the sensor has dried

FEATURES฀..................................................................................

out, automatic irrigation will resume.

Wireless Rain/Freeze-Clik (WRFC)

the WRFC 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 WRC

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.

3. Radio Antenna –

transmits a wireless

signal to the receiver

up to 1000 ft. It is

recommended that the

antenna 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.

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.

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.

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 1,000 ft.

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.

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.

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

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.

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.

12

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.

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 ands 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 12).

Sensor Bypass LED is flashing red:

A. Check that the battery in the transmitter

is good (see page 12).

B. Check for obstructions around the

transmitter or receiver antennae.
