The PC error in Voltas AC indicates that the Outdoor Ambient Temperature is too low, triggering a protection mechanism to safeguard the system. This error occurs when the temperature outside falls below the set threshold for efficient operation, particularly in Cooling Mode. In very low outdoor temperatures, the air conditioner may struggle to extract heat from the environment, and components like the compressor or fan might be at risk of damage. The PC error helps prevent the system from running under these extreme conditions, which could lead to system failure or inefficient cooling performance. To resolve the PC error, ensure that the outdoor unit is not exposed to excessively cold environments, especially in regions where temperatures can drop below freezing. If necessary, relocate the unit to a more sheltered area or install weather protection to maintain proper functioning. Once the outdoor temperature rises to an acceptable level, the PC error will typically clear, and the air conditioner will resume normal operation. Regular maintenance, including checking the outdoor unit’s location and ensuring it is not exposed to extreme cold, can help prevent this error from occurring in the future.
