Introduction
Congratulations on your purchase of
the WR2 Wireless Sensor.
Now in accordance with California
Executive Order B-29-15, prohibiting
the application of potable water to
outdoor landscapes during and within
48 hours after measurable (1/4” or
greater) rainfall.
The Rain Bird Wireless Rain Sensor is
designed for residential and commercial
irrigation systems. It saves water
and extends irrigation system life by
automatically sensing precipitation and
interrupting irrigation during rain and low
temperature events.
Programming logic can suspend irrigation
using the “Quick Shut O ” feature or when
the amount of rainfall exceeds the rainfall
set point. Likewise, the Wireless Rain /
Freeze Sensor will suspend irrigation when
the sensor temperature reading is below the
temperature set point.
At Rain Bird, we are focused on developing
products and technologies that use water in
the most ecient manner possible. The rain
and rain / freeze sensor illustrate Rain Bird’s
commitment to this Intelligent Use of Water.
The product is part of Rain Bird’s family of
water conservation solutions that include
the SMRT-Y Soil Moisture Sensor, U-Series,
HE-VAN, and Rotary Nozzles, and the ESPSMTe controller.
Please read through these instructions in
their entirety or refer to the programming
demo (www.rainbird. com/WR2) before
installing your WR2 Wireless Sensor. Also,
reference your irrigation system controller /
timer installation instructions for the proper
connection of rain sensors.

Irrigation Modes
Programmed Irrigation
WR2 Wireless Sensor is actively managing
the irrigation
controller / timer.
Once a set point
is satised by
environmental conditions, or the “Quick
Shut O ” feature is activated, irrigation is
suspended. An X and corresponding trip
indicator (rainfall, temperature, or both)
will automatically display when irrigation is
suspended.
48-Hour Irrigation Hold Active
WR2-48 Model Only
Irrigation will be prevented
for 48 hours following
measured rainfall. The
display shall ash an X to
indicate the irrigation hold.
Override Sensor for 72 Hours
NOTE: Selecting Override Sensor cancels
any 48-hour hold
on irrigation.
User has elected
to permit
irrigation in accordance with the timer
schedule regardless of environmental
conditions (i.e. rainfall or low temperature
is detected by the sensor). System will
automatically resume programmed
irrigation mode after 72 hours (Note: X
and trip indicator will be displayed when
returning to programmed irrigation mode if
set points are satised).
Synchronize
the Sensor and
Controller Interface
After the Controller Interface is wired
to the irrigation timer, the Sensor and
Controller Interface need to establish a
radio communication link. When the link
is established, the Sensor and Controller
Interface are considered “paired.”

Interface, push
and hold both
arrow buttons
simultaneously to
begin the installation sequence.
2. After the “Sensor Indicator / Pairing
Status” icon ashes, remove the label
from the bottom of the sensor.
3. The ashing “Sensor Indicator / Pairing
Status” icon prompts you to insert the
battery cassette with battery into the
Sensor lower casing as shown. Align the
arrow on the battery cassette with the
unlocked indicator on the bottom of the
Sensor.
4. Rotate the battery cassette clockwise
until the arrow points toward the locked
