NOTE 2 Do not short the remote control unit wires to each other. (The protection circuit will be activated and the units will not operate.)
Once the cause of the short is eliminated, normal operation will then be possible.
NOTE 3 When running the units in heating mode during test operation, be sure to run the units in cooling mode first before selecting this
mode. If heating mode is selected first, it may cause problems with operation of the compressor.
NOTE 4 Be sure to select cooling mode first, and run the unit in this mode for 5 minutes or more.
If the cooling operation is not executed first for five minutes or more, the heating operation can not be executed.(Test operation will
be cancelled automatically after 30 minutes.)
NOTE 5 Test operation mode should always be cancelled once test operation itself has been completed.
NOTE 6 If the self-diagnosis function reports a problem but more than one problem has developed at the indoor and/or outdoor units, the
problem display on the remote control unit may not match the LED display on the outdoor unit printed circuit board. In such cases,
check both locations and remove the causes of the problems.
