B603PRO · HVAC Pump Control
Five Control Modes for HVAC Water Systems
Stable pressure and temperature across changing HVAC demand
B603PRO matches pump speed to system demand with constant temperature, temperature-difference, constant pressure, differential-pressure and manual control modes.

Built for changing HVAC demand
One control platform for different cooling-water applications
B603PRO supports contractors, pump manufacturers and system integrators across building and process-cooling projects.
COOLING TOWERS
Condenser-Water Circulation
Regulate circulation pumps around condenser-water conditions and system demand instead of continuous fixed-speed operation.
DATA CENTERS
Mission-Critical Cooling Loops
Support stable cooling-water circulation where pressure and temperature consistency directly affect equipment reliability.
PROCESS COOLING
Industrial Temperature Control
Use pump-speed control to maintain stable process-water temperature and reduce unnecessary full-speed running.
B603PRO control logic
Five operating modes, explained through three control tasks
Select the control strategy according to the project sensor, hydraulic target and commissioning method.
For systems controlled by supply-water temperature or the difference between supply and return temperatures.
Constant Temperature / Temperature-Difference Control
B603PRO adjusts pump speed to maintain the selected temperature or temperature-difference target, helping the water loop respond to changing thermal loads.
For pump systems controlled by one pressure signal or by the pressure difference across the loop.
Constant Pressure / Differential-Pressure Control
The inverter regulates pump output to maintain the specified pressure target, supporting more stable water delivery as valves open, close and system demand changes.
For commissioning, maintenance or projects that require direct operator control.
Manual Control
Operators can directly set and adjust the operating setpoint during commissioning or controlled operation while retaining the inverter’s pump and motor protection functions.

Before you ask for a quote
Project information we need
A few system details help us give you a more useful B603PRO recommendation.
What should I include in my inquiry?
Pump and motor data, voltage, required flow and head, selected control mode, sensor signal, installation environment, panel requirements and expected quantity.
How do I choose the control mode?
Tell us whether the project must stabilize temperature, temperature difference, pressure or differential pressure. We will help match the signal and control logic before quotation.
Can you support an initial sample and private label?
Yes. A one-piece sample is available, and OEM, ODM, packaging, manual and software customization are supported.
What happens after I submit the form?
Our team will review the project details and contact you as soon as possible.
