RAIN ONLY AND
RAIN/FREEZE SENSOR
for Automatic Irrigation Systems
INTRODUCTION
Thank you for selecting an Orbit
®
RX series Sensor. This sensor will provide conservation, convenience, and
flexibility to your fully automatic watering system. Never again will you see your sprinklers running on a rainy
day. Now, after a set amount of rain has fallen (and/or freezing temperatures for the RX-1.5F), the sensor
engages a switch that will prevent the timer from watering. The added freeze sensor (with RX-1.5F) will provide
peace of mind (when temperatures drops below 37°F [3°C]) by interrupting your sprinklers and reduce the
hazards of standing water freezing on your driveway, sidewalks, and patios. Once the rain sensor has dried
sufficiently, the sensor allows normal sprinkler operation.
