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.
