A wireless weather-sensor path

The Rain Bird WR2-RFC Wireless Rain/Freeze Sensor Complete Kit gives compatible sprinkler controllers a separate outdoor sensor and receiver setup. It supports a controller routine where weather conditions can be part of the watering decision.

The kit needs a compatible controller, a receiver location, and an outdoor sensor location with clear exposure.

Keep the sensor and receiver notes together

Wireless sensor setups have two service points. Label the receiver near the controller and record the outdoor sensor location in the garden notes.

That small record helps during seasonal checks, battery checks if the manual calls for them, and controller service.

Connect weather pauses to zone checks

A rain or freeze sensor should fit into the same record as station names, valve-box labels, and sprinkler-output notes. After setup, run through the controller settings and make sure each station name still matches the yard route.

If controller wiring or sensor behavior is unclear, a qualified irrigation professional can check the system before the seasonal schedule begins.

Good match

Choose this kit for compatible sprinkler controllers that need a wireless rain and freeze sensor path with a separate receiver.

What to know

Confirm controller compatibility, receiver wiring, sensor placement, signal path, outdoor mounting needs, and manual steps before installation.
