Scroll through stored codes using the TEMP set buttons
Press CHECK to cancel service history
Press CLEAR to delete codes
Up to 4 Codes can be stored
Code - Description
E01 Controller (local or network) receives no communication from a master indoor unit- could include that master is
turned off. Also check that there is a master controller
E02 Local controller failure (unable to transmit)
E03 Master indoor unit receives no data to A-B. Often appears as an E01 fault code
E04 Indoor unit (except twin slave) receives no communication from outdoor unit; can include klixon on 560 Digital
Inverter split system – checked by measuring 280VDC across outdoor unit capacitors
