Al l radio transmitters broadcast ener gy
through the air. This energy may interfere with
other electronic devices in close proximity t o

electronic in t er f er enc e:
• Do not place sensitive electronics
(c omput ers , t elephones , r adios , et c .)
in close proximity to the C on tr oller
I n t er fac e or S ensor .
• Use clip-on ferrite sleeves on the
connection or power cables of aff ec t ed

I n tr o duc tion
C ongr atula tions on your pur chase
of the WR 2 Wireless S ensor .
T he Rain Bird Wireless Rain Sensor is desig ned
for residential and commercial ir r iga tion
sy stems . I t saves water and extends ir r iga tion
system life by automatically sensing
precipitation and interrupting ir r iga tion
during rain and low temperature ev en ts .
Programming logic can suspend ir r iga tion
using the “Quick Shut Off ” feature or when
the amount of rainfall exceeds the rainfall
set poin t . Likewis e, the Wireless Rain / F r eez e
Sensor will suspend irrigation when the
sensor temperature reading isbelow the
temperature set poin t .
A t Rain Bird, we are focused on dev eloping
products and technologies that use w a t er
in the most efficient manner possible . T he
rain and rain / freeze sensor illustrate R ain
Bi r d ’ s commitment to this I n t elligen t Use
of W a t er . T he product ispart of Rain Bi r d ’ s
family of water conservation solutions tha t
include the Soil Moisture S ensor , U-Series and
R otar y Nozzles, the ES P-SMT and E T M anager
C on tr ollers .
Please read through these instr uc tions
in their entirety or refer to the
programming demo (w ww .r ainbir d .
com/WR2) before installing your WR2
Wireless Sensor. Also, reference y our
irrigation system controller / timer
installation instructions for the pr op er
connection of rain sensors .

before mounting the de vic e ,
ensure the wires easily r each

•For best per f or manc e , the
Controller I n t er fac e should
be installed at least five f eet

I rriga tion M o des
Programmed I rriga tion:
WR 2 Wireless
Sensor is ac tively
manag ing
the ir r iga tion
controller / timer . Once a set point is sa tisfied
by environmental c onditions , or the “ Q uick
Shut Off ” feature is ac tiv a t ed , irrigation is
suspended . An X and correspondingtr ip
indicator (rainfall, t emperatur e , or both)
will automatically display when irrigation is
suspended .
Suspend I rriga tion for 72 Hours:
Userhas elected t o
temporarily suspend
irrigation for 72
hours . System will
automatically r esume
programmed ir r iga tion
mode after 72 hours (Note: X and tr ip
indicator will be displayed when returning t o
programmed irrigation mode if set points ar e
satisfied).
Synchronize the
Sensor and
C on tr oller I n t erfac e
Afterthe C on tr oller I n t erfac e is wired t o
the irrigation timer, the Sensor and
C on tr oller I n t erfac e need to establish a
radio communication link.When the link
is established, the Sensor and C on tr oller
I n t erfac e are considered “ pair ed . ”
1. On the C on tr oller
I n t er fac e , push and
hold both ar r o w
buttons simultaneously
to begin the installa tion
sequenc e .
2. After the “Sensor I ndica t or / Pairing S ta tus ”
icon flashes , remove the label from the
bottom of the sensor .
3. T he flashing“Sensor I ndica t or / Pairing
S ta tus ” icon prompts you to insert the
ba tt er y cassette with battery into the S ensor
lowercasing as shown. Align the ar r o w
on the battery cassette with the unlocked
indicator on the bottom ofthe S ensor .
Override Sensor for 72 Hours:
Userhas elec t ed
to per mit

when returning to programmed ir r iga tion
mode if set points are satisfied).

5. T he Sensor is successfully paired t o
the Controller I n t er fac e when the
“Sensor I ndica t or / Pairing S ta tus ” ic on
stops flashing . Once pair ed , sensor
signal strength and battery life ar e
communicated via the Controller I n t er fac e

the bottom of the Sensor indicates sig nal
strength for 20 minutes immedia t ely
following successful pair ing . T hese “ self

WR 2 Wireles s Sensor is opera tional .
Programming the
Set P oin ts
T he WR 2 Wireles s Sensor allows the c on tr ac t or
to establish rainfall and temperature set
points appropriate for local en vir onmen tal
and soilc onditions . A lt er na t ely , the c on tr ac t or
may elect to use the “Standard S etting ”:
temperature 37° F (3° C), rain fall ¼” (6mm) and
“ pr og r ammed ir r iga tion ” mode . T he ” S tandar d
S etting ” is programmed at the factory and is
active after successful pair ing .
