The SB655C's configuration is managed through a structured programming menu with three distinct levels:
Finding a direct "repack" manual for the Eliwell SB655 C can be tricky because these units are often integrated into specific commercial refrigeration systems (like those from Costan or Epta). The SB655 C is a programmable controller designed for compressor racks or complex cooling circuits. eliwell sb655 c manual repack
governs complex multi-circuit refrigeration plants and chillers with up to two circuits and four compressor power steps. The SB655C's configuration is managed through a structured
A well-used manual is often opened during troubleshooting. The myEliwell and Eliwell AIR mobile apps are powerful for this, allowing you to read current status, send commands, and check for error codes. Some common issues include: A well-used manual is often opened during troubleshooting
| | Description | Typical Value/Range | Notes | | :--- | :--- | :--- | :--- | | SEt | Temperature Setpoint : The target temperature for the system. | User-defined [LSE...HSE] | Adjustable in the Quick Menu | | diF | Differential (Hysteresis) : The temperature difference that controls when the compressor cycles on and off to maintain the setpoint. | 0.1... 150.0 | Regulator restarts when temperature reaches SEt + diF | | LSE / HSE | Setpoint Limits : The minimum and maximum allowed values for the SEt parameter. | LSE < SEt < HSE | Prevents the operator from setting a dangerously low or high temperature | | Ont / OFt | Fault-Mode Management : Defines compressor behavior (On time / Off time) if the regulation probe fails. | 0... 250 | Ont =0 & OFt =1 means compressor is always off. Ont =1 & OFt =0 means always on | | dbi | Minimum Off Time : Delay between consecutive compressor starts to protect it from short cycling. | 0... 250 min | Protects the compressor from excessive wear | | dt1 / dt2 | Defrost Interval : The time (in hours or minutes) between defrost cycles. | 0... 250 | Defrost is a critical function for heat pumps and refrigeration systems | | HAL / LAL | High/Low Alarm Thresholds : The temperature values that will trigger an alarm. | User-defined | AFd determines if these are absolute or relative to the setpoint | | H00 | Sensor Type Configuration : Selects the correct input type for the connected probe (NTC, PTC, Pt100, etc.) | 0: PTC, 1: NTC, Jtc, Htc, Pt1 | A very common first check for sensor issues |
