| Code | Description | Advanced Use Case | | :--- | :--- | :--- | | | Differential (Hysteresis) | Standard: 2°C. Advanced: Set to 1°C for pharmaceutical storage to reduce temp swings. | | LS / US | Minimum / Maximum Setpoint | Used to lock out technicians from setting temps too high (US) or too low (LS) damaging the compressor. | | OdO | On/Off delay for compressor | Prevents short cycling. Advanced: Increase to 5+ minutes for large semi-hermetic compressors. | | dF | Defrost type | 0 = Electric, 1 = Hot gas, 2 = Off cycle.

Advanced: Set based on evaporator size. Too long wastes energy. | | FSt | Temperature to stop defrost | Evaporator temp probe must reach this value to end defrost early (energy saving). | | Fd | Fan delay after defrost | Prevents blowing hot humid air into the cabinet. Advanced: Set to 2-5 minutes post-drip time. | | ALu | High temperature alarm delay | Prevents false alarms during door openings.
