Match primary or secondary pump output to real cooling demand while maintaining the required pressure or temperature target.


Regulate circulation pumps around condenser-water conditions and system demand instead of continuous fixed-speed operation.


Support stable cooling-water circulation where pressure and temperature consistency directly affect equipment reliability.


Use pump-speed control to maintain stable process-water temperature and reduce unnecessary full-speed running.
Select the control strategy according to the project sensor, hydraulic target and commissioning method.


B603PRO adjusts pump speed to maintain the selected temperature or temperature-difference target, helping the water loop respond to changing thermal loads.


The inverter regulates pump output to maintain the specified pressure target, supporting more stable water delivery as valves open, close and system demand changes.


Operators can directly set and adjust the operating setpoint during commissioning or controlled operation while retaining the inverter’s pump and motor protection functions.
