The NEW Rain Bird ESP-LXIVM 2-Wire System has many powerful and flexible features, starting with the revolutionary new Integrated Valve Module (IVM). This "smart solenoid" stays in constant communication with the controller, providing efficient irrigation and advanced diagnostics. Only half the number of wire splices are needed, improving installation costs and reliability. A simple-to-use interface and advanced diagnostics make ESP-LXIVM the best controller on the market. Two models are available, the ESP-LXIVM for medium size installations and LX-IVM Pro for large scale commercial installations.
