Decoding and error instructions for Daikin air conditioners

Error codes for air conditioners Daikin (Daikin) - decryption and instructionsDaikin air conditioners of the latest generations contain both mechanical and electronic modules. With system problems, it is very difficult to diagnose the problem. Therefore, the equipment is equipped with a self-diagnosis function that detects a failure and notifies the user about it.

Error codes are displayed on the control panel display. If the equipment operates in an emergency mode, a code representing an alphanumeric value blinks on the monitor.
