Test run method
Be sure to configure test run settings only when the outdoor unit has stopped operating.
•
Depending on the communication status between the indoor and outdoor units, it may take several minutes for
the system to start operating after settings for the test run are complete.
•
After the test run settings are complete, all the outdoor units and the connected indoor units will start operating.
Room temperature control will not activate during test run (continuous operation).
•
Test run set with the outdoor unit doesn't stop automatically. Be sure to stop the operation according to the
operation method.
•
All indoor units will operate when test run is performed from the outdoor unit. At this time, the remote controller of
the indoor unit is unavailable.
•
Operation mode cannot be changed during the test run. To change the operation mode, please stop the test run
first, and then perform the test run again. At this time, the compressor cannot be restarted for 3 minutes after it
stops in order to protect the indoor unit. Please restart it after 3 minutes.
