1. Product Overview
The ITRON CF550 is an advanced integrated thermal energy meter designed for precise measurement of energy consumption in tertiary and industrial installations. This versatile device is capable of accurately counting energy in both heating and cooling networks, adapting its function through internal settings. It is an essential component for energy management and recalculation systems.
The CF550 meter integrates seamlessly with existing infrastructure, supporting Mbus and pulse outputs for flexible data acquisition. Please note that the external measuring device (flow sensor) is not included with the CF550 integrator/meter unit.

The transparent casing reveals the digital display showing energy readings in GJ, flow rate in m³/h, and a battery compartment indicating '3.6V 6Y INSTALLED IN 2010'. The meter also displays compliance standards like 'CE', 'CF 55', 'EN 1434 class 2', and 'Environment: class C', along with temperature range and pulse weight specifications.
2. Safety Information
Always adhere to local electrical codes and safety regulations during installation and maintenance. Installation should only be performed by qualified personnel.
- Ensure the power supply is disconnected before any installation or maintenance work.
- Do not open the meter casing unless explicitly instructed by the manufacturer.
- Protect the device from extreme temperatures, direct sunlight, and moisture.
- Avoid exposing the meter to strong electromagnetic fields.
3. Setup
The ITRON CF550 is designed for professional installation within heating or cooling networks. Proper setup ensures accurate energy measurement and reliable operation.
- Mounting: Securely mount the CF550 integrator in the designated location, ensuring it is easily accessible for readings and maintenance.
- Sensor Connection: Connect the temperature sensors (e.g., PT100, EN 60751 compliant) to the appropriate terminals on the CF550. Ensure correct polarity and secure connections.
- Flow Sensor Integration: Integrate the external flow sensor (not supplied) with the system. The CF550 will receive pulse signals from this sensor to calculate energy consumption.
- Network Connection: Connect the Mbus or pulse output cables to your building management system or data logger as required.
- Configuration: The meter can be configured for either heating or cooling applications. This setting is crucial for accurate energy calculation and should be performed during initial setup.
4. Operating
The ITRON CF550 operates automatically once properly installed and configured. The digital display provides real-time energy consumption data and other relevant parameters.
- Display Readings: The primary display shows the accumulated energy in Gigajoules (GJ) or other configured units. Additional information such as flow rate (m³/h), temperature differences, and operational status may also be displayed.
- Units: Energy is typically displayed in GJ (Gigajoules) or MWh (Megawatt-hours). Flow rates are shown in m³/h (cubic meters per hour).
- Navigation: If equipped with buttons, short presses typically cycle through different display screens, showing current values, historical data, or diagnostic information. Refer to the on-screen prompts for specific navigation.
- Data Output: Energy data is transmitted via Mbus or pulse outputs to connected systems for remote monitoring and billing purposes.
5. Maintenance
The ITRON CF550 is designed for long-term, low-maintenance operation. Regular checks ensure continued accuracy and reliability.
- Cleaning: Gently wipe the exterior of the meter with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Battery Life: The internal battery (e.g., 3.6V 6Y) has a long lifespan, typically several years. The display may indicate when the battery was installed (e.g., 'INSTALLED IN 2010'). Battery replacement should only be performed by authorized service personnel.
- Visual Inspection: Periodically inspect the meter for any signs of physical damage, loose connections, or leaks.
- Calibration: Energy meters require periodic calibration to maintain accuracy. Consult with a certified service provider for calibration schedules and procedures.
6. Troubleshooting
If you encounter issues with your ITRON CF550, consider the following common troubleshooting steps:
- No Display: Check the power supply to the meter. If battery-powered, the battery may be depleted. Contact service personnel for battery replacement.
- Incorrect Readings: Verify that the temperature sensors are correctly installed and functioning. Ensure the flow sensor is operating properly and that the meter is configured for the correct application (heating/cooling).
- Communication Issues: Check the Mbus or pulse output connections. Ensure the receiving system is correctly configured to communicate with the CF550.
- Error Codes: If the display shows an error code, note the code and consult the manufacturer's technical documentation or contact support.
For persistent issues or complex problems, it is recommended to contact qualified technical support.
