| Code | Description | Typical Cause | Solution | | :--- | :--- | :--- | :--- | | | Evaporator fan lock / Overload | Fan motor thermal switch triggered or rotation sensor missing. | 1. Check fan motor bearings. 2. Reset manual fan thermal switch. 3. Verify Fc (Fan configuration) parameter. | | dF | Defrost timeout | Defrost lasted longer than dt (Max defrost duration) without terminating. | 1. Check defrost heater/valve. 2. Verify evaporator probe (Pb2) is working—termination not detected. 3. Increase dt (typical: 45 min for electric, 30 min for hot gas). | | Code | Description | Typical Cause |

| Code | Description | Typical Cause | Solution | | :--- | :--- | :--- | :--- | | | High Temperature Alarm | Room temperature > AL2 (High alarm setpoint) for longer than ALd (Alarm delay). | 1. Check if compressor is running. 2. Verify refrigerant charge. 3. Check for blocked condenser or open door. 4. Adjust AL2 parameter. | | LA | Low Temperature Alarm | Room temperature < AL1 (Low alarm setpoint) for longer than ALd . | 1. Check thermostat setpoint ( St ). 2. Verify defrost is not stuck ON. 3. Check for evaporator fan failure. | | dA | Door Open Alarm | Digital input detected door open for > Ado (Door open alarm delay). | 1. Close the door. 2. Check door switch on terminals 3 & 4. 3. Disable door alarm via i2P parameter if no switch exists. | | CA | External Alarm | Generic alarm triggered by external device (via digital input). | 1. Check external safety (pressure switch, thermal overload). 2. Configure i1F or i2F parameters. | | SA | Serious External Alarm | High-priority external alarm; forces compressor OFF. | 1. Identify external safety device (e.g., high-pressure switch). 2. Reset the safety device manually. |
