Improper wiring can permanently damage the controller microprocessor or the refrigeration compressor. Always disconnect the main power supply before handling electrical connections. Terminal Connections Main power supply input (230Vac). Terminal 3: Common line for relay outputs. The Eliwell SB655 C separates parameters into two

| Label | Description | Notes | | :--- | :--- | :--- | | | | | | SEt | Temperature Setpoint for the controlled medium. | - | | diF | Differential (Hysteresis). The compressor stops at SEt and restarts at SEt + diF . | Value cannot be zero | | HSE | Maximum allowable Setpoint value. | Prevents user error | | LSE | Minimum allowable Setpoint value. | Prevents user error | | Operating Mode | | | | HC | Regulator operating mode. Set to C for cooling (chiller) or H for heating (heat pump). | Caution: Changing this may require reconfiguring other parameters | | Defrost Settings | | | | tdF | Type of defrost (e.g., Electrical, Hot Gas). | Configure based on system | | EdF | Defrost interval between cycles. | - | | MdF | Maximum duration for a defrost cycle. | Safety cut-off | | Fan Management | | | | FSt | Fan stop temperature (when the evaporator is very cold). | Optimizes system efficiency | | FOn / FOF | Differential temperatures to cycle fans on/off. | - | | Alarm Parameters | | | | ALu / ALL | High and low temperature alarm thresholds. | Defines the acceptable temperature range | | PAL | Delay time for an alarm to be triggered after a threshold is crossed. | Prevents nuisance alarms |
