2-Wire Benefits Without the Hassle

The ESP-2WIRE Controller and 2W-1 Decoder continue Rain Bird’s legacy of the best-in-class 2-wire experience with an approachable platform for projects up to 50 stations.

With new Decoder Auto-Address functionality all decoders connected to the 2-wire path are found and assigned to stations providing significant time savings.  After decoders are programmed, the ESP-2WIRE Controller programs just like the popular ESP-ME3 Controller. 

With no special wire, wire connector or grounding requirements, contractors can now take advantage of all 2-wire benefits with a familiar platform that’s easy to install and program.
