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.
