When [J] zone is detected for 6 minutes (Following figure), the commanded frequency is decreased from the real operation frequency. After then the commanded frequency changes every 30 seconds while operation is performed in [J] zone.

In [K] zone, time counting is interrupted and the operation is held.

When [ I ] zone is detected, the timer is cleared and the operation returns to the normal operation.

If the commanded frequency becomes S0 because the operation continues in [J] zone, the return temperature A is raised from 5°C to 12°C until [ I ] zone is detected and the indoor fan operates with [L] mode.
