Orbit Rain and Freeze Sensor 57069 — 24 VAC compatible, adjustable sensitivity & 30 ft lead

Orbit Rain and Freeze Sensor 57069 automatically pauses your sprinkler controller during rainfall or freezing conditions, then resumes normal watering when conditions clear.

Save water and protect pipes with a compact, adjustable sensor that connects to most 24 VAC irrigation controllers. The unit senses moisture with expandable water-absorbing disks and monitors temperature with a built-in thermistor, suspending irrigation when rain or low temperatures are detected and restoring the schedule when safe. It’s designed for eave or open-air mounting and comes with a weather-resistant lead to reach the controller.

How does the sensor stop sprinklers when it rains?

The sensor uses a stack of super-absorbent disks that swell as they take on moisture. When the disks expand they mechanically trigger the sensor to open the controller circuit, which prevents scheduled zones from running until the disks dry and contract.

• Expandable disks absorb water and cause a temporary circuit open.
• Adjustable sensitivity from light showers to heavier rainfall.
• Restores the controller automatically after disks dry, no user action required.

What temperature threshold triggers the freeze protection?

The built-in thermistor monitors air temperature and suspends irrigation when it detects freezing or near-freezing conditions. This helps avoid irrigation during temperatures that could freeze pipes or damage plants, and irrigation resumes when temperatures return above the set threshold.

• Thermistor senses low temperatures to prevent winter watering.
• Automatically restarts the schedule as temperatures rise.
• No complex programming required—connect to the controller’s rain sensor port.

How do I install and adjust the Orbit sensor?

Mount the sensor in an exposed location such as an eave, fascia, or pole for accurate rain and temperature readings. Run the weather-resistant lead (up to 30 ft) to the controller’s rain sensor terminal; then set the rain sensitivity wheel to the desired rainfall trigger.

• Mount on an eave or other open-air spot for unobstructed sensing.
• Wire length supports up to a 30-foot run to the controller port.
• Simple sensitivity adjustment lets you choose the rainfall threshold.

Which sprinkler controllers work with this Orbit unit?

The sensor is built for compatibility with 24 VAC irrigation controllers from Orbit, Hydro-Rain, and most major brands. It connects to the controller’s rain sensor terminals and acts as a normally closed device that opens during rain or freeze events.

• Designed for standard 24 VAC controller rain sensor ports.
• Works with Orbit and Hydro-Rain controllers and common third-party systems.
• Acts as a weather-triggered interrupt to the controller schedule.

Who this is for: Homeowners and property managers who want a low-cost, reliable way to prevent unnecessary watering during rain or freezing conditions. It’s ideal for those with automatic 24 VAC irrigation controllers seeking water savings, pipe protection in winter, and a simple plug-and-play device that needs little maintenance.
