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 Off " 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 efficient 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 ESP-
SMTe 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.
