Overall Verdict:
A functional but dense technical manual. It contains all necessary information for installation, programming, and troubleshooting—but lacks clear organization or real-world examples, making it challenging for first-time users. eliwell sb655 c manual
| Symptom | Possible Cause | Solution |
|---------|----------------|----------|
| Compressor does not start | Anti-short cycle (AC) active | Wait. Reduce AC if needed. |
| | Setpoint > room temp | Lower setpoint. |
| | Probe defective | Replace probe. |
| Continuous defrost | dE set too high, or dS too low | Reduce dE, increase dS. |
| Display shows OFF | Unit in standby | Press ON/OFF for 3s. |
| Erratic temperature | Wrong probe type (P2) | Set P2 to match probe. |
If the SB655 C is beeping or flashing, here is what the manual says: | Parameter | Value | |-----------|-------| | Power
| Error Code | Meaning | Solution | | :--- | :--- | :--- | | P1 | Probe 1 (Ambient) shorted or open circuit. | Check wiring on terminals 1 & 2. Replace probe (10k NTC). | | P2 | Probe 2 (Evaporator) fault. | Check wiring on terminals 3 & 4. Jumper between 1 & 4 present? | | HA | High temperature alarm (exceeded AL2). | Check if door is open, condenser is dirty, or gas is low. | | LA | Low temperature alarm (below AL1). | Check if setpoint is too low or if probe is unplugged in warm air. | | EE | Internal memory failure. | Controller is faulty. Replace SB655 C unit. | | cEF | Defrost timeout – evaporator did not end defrost. | Defrost duration (c5) too short, or heater is burnt out. | | dor | Door open alarm (if digital input enabled). | Close the door or check door switch terminals 5-7. |
