Wireless Rain-Clik Rain Sensors
Installation Instructions
®
INTRODUCTION
In most installations, the Wireless Rain-Clik™ acts as a switch to break the
circuit to the solenoid valves of the irrigation system when it has rained. This
allows the timer to advance as scheduled, but keeps the valves from opening
the water flow. Once the Wireless Rain-Clik™ has dried sufficiently, the switch
closes again to allow for normal operation.
MOUNTING
Standard Mount:
Using the screws provided, mount the Wireless Rain-Clik™ transmitter on any
surface where it will be exposed to unobstructed rainfall, but not in the path of
sprinkler spray. The switch-housing portion must be upright (as pictured), but
the swivel-bracket can be moved for mounting on any angled surface.
Gutter Mount:
Clip the enclosed gutter mounting bracket over the inside lip of the gutter. Attach
the Wireless Rain-Clik™ to the gutter mounting bracket with the screws provided.
Helpful Hints for Mounting:
A. When looking for a suitable location such as on the side of a building or post,
the closer the Wireless Rain-Clik™ is to the controller, the better reception
will be. DO NOT EXCEED 300 feet.
B. The ideal location for mounting is not always the most practical location. In
the case where a compromise must exist (such as low location on a side wall
rather than the preferred high location), note that the Wireless Rain-Clik™
will still work as it will always receive some rainfall – it just will not be as
accurate in its gauging as it could be.
C. As described in the
“Operation” section of
this manual, “reset
rate” refers to the
amount of time it takes
the Wireless RainStandard
Clik™ to dry out
Mount
sufficiently for the
sprinkler system to be
allowed to come back
on. The mounting
location will affect this
rate and should be
taken into consideration should extreme
conditions exist. For
example, mounting the
Wireless Rain-Clik™
on a very sunny,
southern end of a
building may cause the
Wireless Rain-Clik™
Gutter
to dry out sooner than
Mount
desired. Similarly,
mounting on the
northern end of a
building with constant
shade may keep the
Wireless Rain-Clik™
from drying
soon enough.
Transmitters/Sensor
• Nothing to set up with
this unit after installation
• The unit can be tested
stand-alone as follows:
press and hold the post
on the quick response
Manually depress the spindle at
section. Within 3
the top of the Wireless Rain-Clik
seconds of pressing
and holding this post
down, the LED
protruding from the
potting should blink
once. Release the post,
within 3 seconds the
LED should blink once
again. (Figure 1)

Note: The pump circuit
output must be 24 Volts

Learning the transmitter address at the receiver:
• Units purchased as a kit will already have their address learned.
• Each transmitter produced has a unique address hard-coded into it. A receiver
must learn this address to work with that transmitter. This step will only be
necessary if transmitters and receivers are purchased separately.
1. Prior to applying power (yellow wires) to the receiver, press and hold the
receivers pushbutton.
2. While the pushbutton is being held apply power to the receiver – the receiver’s
“sensor status” LED should light up yellow indicating the receiver is ready to
learn an address.
3. Push and hold the quick response post on the transmitter/sensor.
4. Within 4 seconds, the receiver’s “sensor status” LED should turn red.
5. Release the transmitter/sensor’s quick response post and within 4 seconds
the LED on the receiver should turn green. The address is now learned and
will be retained even in the event of a power outage.

OPERATION
Once the receiver and transmitter have been installed and the receiver has
learned the transmitter's address, the system is ready to work. The receiver has
two LEDs, which indicate the state of the system. The STATUS LED will be RED
when the sensor is wet (watering disabled), and GREEN when the sensor is dry
(watering enabled). There is also a RED BYPASS LED on the receiver. If this
LED is lit, the rain sensor is bypassed and watering will always be allowed. Even
though the sensor is bypassed, the STATUS LED will continue to alert you of the
state of the sensor (Wet or Dry). If the communication between the transmitter
and the receiver ever breaks down, the transmitter’s status LED will flash red.
ADJUSTMENTS AND OPERATION
The Wireless Rain-Clik™ can keep the irrigation
Figure 6
system from starting or continuing after rainfall.
The time that it takes the Wireless Rain-Clik™ to
reset for normal sprinkler operation after the rain has
stopped is determined by weather conditions (wind,
sunlight, humidity, etc.) These conditions will
Vent Ring
determine how fast the hydroscopic discs dry out,
and since the turf is also experiencing the same
conditions, their respective drying rates will roughly
parallel each other. So when the turf needs more
Vents
water, the Rain-Clik™ is already reset to allow the
sprinkler system to go at the next scheduled cycle.
There is an adjustment capability on the Wireless
Rain-Clik™ that will slow down the reset rate. By opening the “vent” (see Figure
6) to completely or partially cover the ventilation slots, the hydroscopic discs will
dry more slowly. This adjustment can compensate for an “overly sunny”
installation location, or peculiar soil conditions. Experience will best determine
the ideal vent setting.
BYPASSING THE SENSOR
The sensor may be bypassed by using the built in bypass feature in the SRC,
Pro-C or ICC. On other controllers the sensor may be bypassed by pressing the
“BYPASS” button on the receiver. The RED BYPASS LED on the receiver will
be lit when the sensor is bypassed. Pressing the “BYPASS” button again will
cause the RED BYPASS LED to go back out thus re-enabling the sensor.
Battery Life: The Wireless Rain-Clik™ transmitter is designed to work daily for
up to ten years with the original battery. The sealed unit is available as a
replacement part. Should you need to change the transmitter the receiver will
have to learn the new transmitter address.
There is no required maintenance for the unit. The Wireless Rain-Clik™ does
not have to be removed or covered for “winterizing” purposes.
TROUBLESHOOTING
Follow these simple checks first before assuming the unit is bad and replacing it.
System will not come on at all:
A. First, check to see that the Wireless Rain-Clik™ discs are dry and the switch
“clicks” on and off freely by pressing the top of the spindle.
B. Next, look for breaks in the wire leading to the Wireless Rain-Clik™ receiver
and check all wire junctions.
System will not shut off even after heavy rainfall:
A. Check wiring for correctness (see “Operation Check to Verify Correct Wiring”).
B. Is the rainfall actually hitting the Wireless Rain-Clik™? Check for obstructions
to rainfall such as overhangs, trees or walls.
