Introduction
The Toro RainSensor connects to your irrigation
system controller/timer to suspend automatic
watering operation in the event of rain. Designed
for ease of installation, your sensor-controlled
irrigation system will be up and running in minutes.
Before attempting to install the RainSensor, please
read through these instructions in their entirety.
Since the RainSensor is designed to work with
most makes and models of controllers, you should
also refer to the instructions provided with your
irrigation system controller for specific information
regarding the connection and use of a rain sensor
or rain switch.
Important: Please note the following information regarding
installation and use of the RainSensor.
• The RainSensor is designed to operate with 24 V ac power
only. Connecting the RainSensor control wiring to 120/240 V ac
power may result in severe equipment damage.
• Installation methods must comply with all applicable national
and local building codes. If you are unsure about proper wiring
practices, have a qualified contractor perform the installation
for you.
• The RainSensor unit should never be submerged in water or
installed inside a rain gutter.
