INTRODUCTION
Thank you for selecting the K-Rain
®
Universal Wireless Rain/Freeze Sensor .
The Universal Rain Sensor Receiver allows installation with most irrigation
controllers – regardless of the manufacturer . Once successfully paired with
the K-Rain Wireless Rain/Freeze Sensor, the controller will be able to expertly
manage water efficiency by suspending watering during rain and/or freeze
periods .
After a set amount of rain has fallen and/or freezing temperatures exist, the
sensor will trigger the controller to suspend watering . The freeze sensor
interrupts your sprinklers and reduces the hazards of standing water freezing
on your driveway, sidewalks, and patios when temperatures drop below 37°F
[3°C] . Once the rain sensor has dried sufficiently, the sensor allows normal
sprinkler operation . Works with most new and existing sprinkler systems .
This rain sensor will NOT work with open circuit controllers .
WARNING: Use with 24V AC power only! Connecting this sensor to 120V or
240V AC power may result in severe equipment damage.
