Forgot-to-open Valve Alarm

1. Error Detection Method

Detection is performed only in the test run. When once detected or the test run finished without any error, the second detection will not be done.
In case of forgetting to open a valve, P04 (high-pressure switch operational alarm) is occasionally preceded due to the following conditions.

  • The status of small temperature change of the oprating indoor unit continues for 3 minutes even after 5-minute to 15-minute since the cooling test run has started.
  • The status of small temperature change of the oprating indoor unit continues for 3 minutes even after 7-minute to 15-minute since the heating test run has started.
