Malfunction code: system test run not yet
executed (system operation not possible)
Execute system test run.
An error occurred during the test run Re-execute the test run.
, Test run aborted Re-execute the test run.
, Test run aborted due to communication issues Check the communication wires and re-execute
the test run.
Indoor unit communication error Check user interface connection.
Warning because there is an error on another
indoor unit
Check if other indoor units have a malfunction
and confirm if indoor unit mix is allowed.
Connection malfunction over indoor units or type
mismatch
Check the type of indoor unit that is currently
connected. Make sure that a correct indoor unit
(only one EKEA or one compatible air curtain) is
connected. If an incorrect type of indoor unit is
connected, replace it with the correct one. After
the correct indoor unit is connected long-press
BS3 to complete the identification of indoor unit.
Connection malfunction over indoor units or type
mismatch
Check if other indoor units have a malfunction
and confirm if indoor unit mix is allowed.
Wrong outdoor unit connected Disconnect the outdoor unit.
