T wist together these two wires along
with one wire from the Rain-Clik™,
and secure with a wire nut. Attach
the other wire of the Wireless Rain-
Clik™ receiver to the “common”
terminal on the controller. Note: The
pump circuit output must be 24 V olts
in this situation. Do not proceed
if 110V .
SETTING THE TRANSMITTER ADDRESS A T THE RECEIVER
Units purchased as a kit will alread y have their address learned.
No addressing is necessary , ho wever if the receiver or transmitter is
replaced, you need to reset the address.
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 (yello w wires) to the receiver , press and hold the
pushbutton on the receiv er .
2. While the pushbutton is being held apply po wer to the receiver – the
receiver’ s “sensor status” LED should light up yello w 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 receiv er’ s “sensor status” LED should tur n 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 no w learned and
will be retained ev en in the e vent of a pow er outage.
OPERA TION
The receiver has tw o LEDs, which indicate the state of the system. The
ST A TUS 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
BYP ASS LED on the receiver . If this LED is lit, the rain sensor is bypassed
and watering will alwa ys be allowed. Even though the sensor is b ypassed, the
ST A TUS LED will continue to aler t you of the state of the sensor (W et or Dr y).
ADJUSTMENTS AND OPERA TION
The Wireless Rain-Clik can keep the irrigation system from star ting or
continuing after rainf all or freezing conditions (Wireless Rain/F reeze-Clik).
The time that it takes the Wireless Rain-Clik to reset for
normal spr inkler operation after the rain has stopped
is determined by weather conditions (wind, sunlight,
humidity , etc.). These conditions will deter mine how f ast
the discs dry out, and since the turf is also experiencing
the same conditions, their respectiv e dr ying rates will
roughly parallel each other .
There is an adjustment capability on the Wireless Rain-
Clik that will slow down the reset r ate. By closing the
“vent” (see Figure 6) to completely or par tially cover
the ventilation slots , the discs will dr y more slowly .
This adjustment can compensate for an “overly sunny” installation location, or
peculiar soil conditions. Experience will best deter mine the ideal vent setting.
No adjustment is required for the freez e sensor por tion of the wireless
Rain/F reeze-Clik. The Wireless Rain/Freez e-Clik will automatically disable
the Irrigation system when temperatures fall belo w 37°F . Although Freez e
Sensors are designed to automatically prev ent watering near or below freezing
conditions, visual chec ks and prudent manual watering suspensions should be
used in conjunction with any freeze sensor
BYP ASSING THE SENSOR
The sensor may be b ypassed by using the b uilt in bypass f eature in the SRC,
Pro-C or ICC. On other controllers the sensor may be bypassed b y pressing the
“BYP ASS” button on the receiver . The RED BYP ASS LED on the receiver will be
lit when the sensor is bypassed. Pressing the “BYP ASS” button again will cause
the RED BYP ASS LED to go back out thus re-enab ling the sensor .
Battery Life: The Wireless Rain-Clik transmitter is designed to work daily for
up to 12 years with the maintenance-free battery . The sealed unit is a vailab le
as a replacement par t. Should you need to change the transmitter the receiv er
will hav e to learn the new transmitter address.
There is no required maintenance for the unit. The Wireless Rain-Clik does not
hav e to be remov ed or covered f or “winterizing” purposes.
TROUBLESHOO TING
Follo w these simple checks first bef ore 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 dr y and the switch
“clicks” on and off freely by pressing the top of the spindle.
B. Next, look f or breaks in the wire leading to the Wireless Rain-Clik receiv er
and check all wire junctions .
C. V er ify temperature (f or Rain/F reeze-Clik installations).
System will not shut off even after heavy rainfall:
A. Chec k wiring for correctness (see section on wiring to your irrigatio n system).
B. Is the rainf all actually hitting the Wireless Rain-Clik? Chec k for obstructions
to rainf all such as overhangs , trees or walls.
