Xylem’s TECHNOLOGIC VFD series combines two advanced controller functions — the Start-Up Genie and an electronically controlled bypass — engineered to reduce on-site setup and configuration time. A built-in auto set mode is available that remembers previously set parameters, enabling users to quickly make adjustments without inputting measurements. Set-up time is about 15 min. It has the ability to alter hydraulic performance to maintain constant system pressure. The drive provides constant speed lag control and the ability to control one variable-speed pump with up to two fixed-speed lag pumps triggered by relay.
