NOTE
• The test run is a forced run that ignores the set temperature. Be sure to stop the test run after work, paying
attention to the room temperature.
• After 60 minutes, the test run will be completed to protect the equipment, and the normal operation will be
started according to the set temperature. However, note that if the remote controller less setting is set, some
indoor models will not complete the test run even after 60 minutes have passed.
