The blueMaster compact 3 (3 control loops) and blueMaster compact 6 (6 control loops) units are designed as control units for smaller applications or for use in the service sector. Both devices have an adaptive optimization of the control, i.e. the device adapts its control behavior to the connected load without user intervention. This eliminates the need to set PID parameters. The control remains stable even with the smallest loads. Four operating modes (control, master mode, monitor) are available per zone.
