Wireless RainSensor™

No wires. No hassle. Just reliable rain sensing that provides optimum
water savings. Toro® innovative wireless technology provides easy to
use, advanced features for prompt reaction when it starts to rain. With
options for rain or rain/freeze sensing, the TWRS Series can save up to
30% more water than existing disc rain sensors.

Features & Benefits

Selectable Water Management Modes

Delay resumption of irrigation by intelligently extending beyond mechanical
reset time – can save up to 30%* more water.

Smart Bypass™
Allows for system override at any time and resets automatically.

Rain/Freeze Combination
Features digital programmable accuracy – a first in the industry – The Freeze
shutoff can be set from 35°F to 45°F in 2° increments.

LCD Display – A First In Wireless Rain Sensors
Provides informative system feedback including outside temperature, and
transmitter signal strength and battery life.

Wired Rain Sensor

When it rains sometimes all you need is a simple sensor that ensures the
job gets done. With multiple set-points for adjustable rain sensitivity and
maintenance-free sensing disks, Toro’s TRS provides the reliability required.
The Quick-Clip™ gutter bracket needs no special tools for installation. It really
is that simple.

Features & Benefits

Compatible With All Toro And Other Manufacturer’s Controllers
Universal Normally Open and Normally Closed operation for compatibility with all
controllers that are designed to accept a sensor device.

Maintenance Free Hygroscopic Discs
Industry standard sensing discs with adjustable rain shut-off indexes at 1/8”, 1/4”,
1/2” and 3/4” of rain.

25 Feet Of UV-Resistant Cable
Includes 25 feet of white outdoor-rated, UV-resistant cable.

Water Conservation Modes
Selectable water conservation modes delay resumption of irrigation by intelligently extending beyond mechanical reset time and can save you up to 30%* more water (savings vary based on sensor setting, watering schedule and other conditions).
