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.
Commissioning of SV unit safety system is not
completed
Complete commissioning of SV unit safety
system. Refer to SV unit manual for more
information.
Indoor unit communication error Check user interface connection.
, Malfunction code: faulty wiring to Q1/Q2 Check Q1/Q2wiring.

line
Check indoor unit amount and total capacity
connected.
Warning because there is an error on another
unit (indoor/SV unit)
Check if other indoor units/SV units have a
malfunction and confirm if indoor unit mix is
allowed.
