Description
CUE is a variable frequency drive (VFD) designed for effective speed control of and Grundfos pump without integrated drives. CUE offers several pre-set application control modes, including constant pressure, constant level (with or without stop function), proportional differential pressure, proportional pressure, and constant temperature. These pre-configured control modes make it easier to program the drive for specific applications. When the system is controlled externally, the open loop control mode is used, providing the CUE with the necessary speed information.
