Essential Parameters for Refrigeration

| Parameter | Name | Recommended Setting | Why it matters | | :--- | :--- | :--- | :--- | | SP | Setpoint | 2°C to 5°C (Cooler) | The target temperature. | | Hy | Differential (Hysteresis) | 1.0°C to 2.0°C | Prevents short cycling. If SP=3°C and Hy=2°C, the compressor cuts in at 5°C and out at 3°C. | | LS | Minimum Setpoint Limit | -30°C | Prevents users from setting a temp too low. | | US | Maximum Setpoint Limit | 10°C | Prevents users from setting a temp too high. | | OdO | Off delay after defrost | 0 minutes | Time delay before compressor re-starts after defrost (dripping time). | | dtE | Defrost type | EL (Electric) or IN (Hot gas) | Critical setting. Wrong type blows fuses. | | idd | Interval between defrosts | 6 (hours) | How often defrost runs. | | Ld | Maximum defrost duration | 30 (minutes) | Safety timer to prevent overheating coils. | | ALu | High temperature alarm | 10°C | Alerts if the cold room stays above 10°C. | | ALL | Low temperature alarm | -5°C | Alerts if freezing too much (for coolers). | Core Functionality Inspect the digital input configured for
