Orbit 57069N Sprinkler Controller Sensor

The rain and freeze sensor for sprinkler controllers is engineered to automatically detect rainfall or low temperature conditions and turn off a sprinkler controller until normal watering conditions return. This sensor is designed to prevent your automatic sprinkler system from watering during a storm, and it is adjustable to accommodate rainfall from 1/8 inch to 1 inch. Additionally, the freeze sensor reduces hazards and damage to your pipes from freezing water.

The sensor uses water-absorbing disks that expand when wet, causing the controller to suspend watering. When the disks dry out and contract, the controller returns to the normal watering schedule. The sensor is adjustable, allowing you to change the threshold for triggering a delay.

It also utilizes a thermistor to detect low temperatures and similarly suspends and restarts watering. You will typically mount the sensor on an eave or other open-air area, and a weather-resistant wire runs up to 30 feet to the rain sensor port of the irrigation controller.

The rain and freeze sensor is compatible with 24 VAC controllers from Orbit, Hydro-Rain, and other major irrigation brands. This device automatically detects rainfall or low temperature conditions and turns off the sprinkler controller until normal watering conditions return, ensuring your plants and pipes are protected.

In summary, the key features of this sensor include:

• Automatically detects rainfall or low temperature conditions
