Pay attention to the followings to perform the test.
- For indoor units or outdoor units in the refrigerant system to be tested, check that there are no errors, they are not in maintenance mode, and they are not in the status of emergency stop.
- Check that the indoor unit to be tested is the same as the indoor unit that is actually installed.
  If the test is performed when the indoor unit is not properly scanned due to bad timing of power-on, etc., it may cause a malfunction.
- If oil recovery operation or defrosting operation starts during test, the test period may be extended.
- When the test is performed, do not change the operation settings of indoor unit to be tested from other controllers or managing devices (UTY-RNR*Z*、UTY-DTG*Z*、UTY-ASGXZ*, etc.).
  In addition, when the test is performed, do not perform the other functions (such as Function Setting) that affect the operation status for above controllers.
  It may cause the test itself to fail or the data from the test results to be inadequate.
