- No specialty PE-cable: Easily install the FG100 with a standard 18g irrigation wire.
- *Shielded cable is required in residential installations where electrical interference is likely, but in some scenarios, standard cable may still be used when proper wire distance from potential sources of electrical interference is maintained
- Threaded unions: Threaded unions allow for faster installation and easy maintenance.
- Rain Bird App: Pair the FG100 with the ESP-ME3 Controller to check system health from anywhere, and control advanced flow settings via the Rain Bird Mobile App. Available for iPhone and Android.
