Hyundai Air Conditioner Error Codes

 Protection and Failure Display

  • When protection display is available, controller will show error code, digital LED shows error code and setting temperature by turns.
  • If there is more than one failure, it will show at first that in front of the error list.
  • Protection display function can be selected in hardware, and the default don’t display;
  • To insure of in and out communist is credibility, the failures relate to outdoor unit will remain failure state for 2 minutes max after recovered.
  • In all failures, only sensor failures don’t have to repower to cancel.

Outdoor Failure Display

There is a LED on outdoor power board, when compressor is running; it is normally light; when no feedback of signal to power board from compressor, it will wink by lighting 1s and going out 1s. If failures happened, it will light 0.5s, go out 0.5s, winking several times and go out 3s for a cycle to indicate failures. The failure list is the follow:

Midea VRF Error Codes

  R410A All DC Inverter V4 Plus R Series 50/60Hz Error Codes: V4 VRF:  Advanced 3-pipe technology enables  heat recovery  between indoor units for unprecedented economy and performance. It can simultaneously operate in cooling and heating mode when it is necessary to provide more freedom for operation. It compensates and adjusts when there are hot and cold rooms in the same building, depending on the direction of sunshine. As a result, it reduces annual power consumption. Midea VRF Error Codes Error Codes Problem E0 Communication error between outdoor units. Only display on the faulty slave unit, all the ODUs are in standby. E1 Phase sequence error. Display on the faulty unit, all the ODUs are in standby. E2 Communication error between indoors and the master unit. Only display on the master unit, all the ODUs are in standby. E4 Outdoor ambient temperature sensor (T4) and condenser pipe temperature sensor (T3/T5) error. Display on the faulty unit, all the ODUs are in ...
