Rachio compatibility with Hunter SRC


Rachio is NOT affiliated or authorized by HUNTER; the HUNTER brand controller and rain sensor are manufactured by HUNTER. This article is intended for instructional and compatibility purposes only.

Rachio does not recommend the use of 3rd party sensors unless required by local code. Remember to always enable Weather Intelligence features to skip watering schedules BEFORE it rains; rain sensors will only skip watering schedules AFTER it rains.

Are you replacing a Hunter SRC with a rain sensor?

Please read these instructions carefully if you are replacing a Hunter SRC controller that has a rain sensor wired in.

Does your wiring look like this?

The pink wire in the picture above is connected to the common terminal, but it is not the common wire for the zone valves; this wire goes to the rain sensor. The white common wire for the zone valves is connected to the RS terminal. When you install the Rachio controller, the zone valve common wire (typically white), must be connected to the common terminal on the Rachio.
