The Eliwell SB655/C (often part of the Energy Flex series) is a universal parametric controller designed for centralized air-conditioning units, chillers, and heat pumps. Its manual provides critical guidance on managing up to two refrigeration circuits and balancing up to four compressor power steps. Core Capabilities & Technical Profile
According to the SB655 technical data sheet, the controller is engineered for complex HVAC/R environments:
Compressor Management: Supports Scroll, Semi-Hermetic, and Screw compressors with balanced operating hours.
Multi-Input Flexibility: Features 5 sensor inputs compatible with NTC, 4–20 mA, and 0–10 V signals.
Output Configuration: Includes 6 relay outputs and supports variable frequency drives (VFD) for both compressors and water pumps.
Climate Intelligence: Includes automatic summer-winter changeover and "Free Cooling/Heating" logic to optimize energy based on outdoor conditions. User Interface & Navigation Download the manual only if:
The Energy Flex manual highlights a 4-digit display with 18 icons. Access is divided into three security-coded levels: End User: Basic monitoring and setpoint adjustments. Service: Maintenance settings and alarm history viewing.
Constructor: Deep configuration of digital and analogue outputs. Programming & Monitoring
Copy Card: A physical "Copy Card" can be used to upload or download parameter maps between devices without manual entry.
Communication Protocols: The SB655/C natively supports Modbus RTU and Televis, allowing for remote monitoring and integration into building management systems.
Alarms: Common codes such as E1 (cell probe error) or E2 (defrost probe error) indicate shorted or interrupted sensors.
For full configuration tables and wiring diagrams, you can refer to the official Eliwell documentation or technical manuals provided by specialized retailers like Electric Automation Network.
