Daikin 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.
