KSB Calio Circulation pump

Use cases

• Monitor calculated flow and head values on a live dashboard to verify pump sizing and performance.
• Create an alert when error value 1 or error value 2 indicates a pump fault, enabling rapid response.
• Track energy consumption and total flow over time to generate efficiency reports for building owners.
• Remotely adjust setpoint speed to optimize pump performance without a site visit.
• Monitor motor and fluid temperatures to detect overheating conditions before they cause damage.
• Log operational hours per pump to schedule preventive maintenance at the right intervals.

Installation

1. 1Wire the Modbus RTU connection (A, B, GND) from the KSB Calio pump terminal to the RS485 port on your ModbusCloud gateway (MCG or MLP series).
2. 2Set the Modbus slave address on the KSB Calio pump according to the Installation and Operating Manual, ensuring it does not conflict with other devices on the bus.
3. 3Confirm the baud rate on the pump is set to 19200, matching the template configuration.
4. 4Import the KSB Calio template in the ModbusCloud platform and assign it to the correct gateway and slave address.
5. 5Verify that live readings such as calculated flow, pump power, and temperatures appear in the ModbusCloud dashboard.
6. 6Test write functionality by changing the operation mode or setpoint speed from the dashboard and confirming the pump responds.
