be set. When the indoor unit discharge air temperature falls down at cooling operation, outdoor fan stops and compressor
frequency forcibly decreases to prevent a drop in discharge air temperature. If the outlet temperature decreases and the
temperature is less than Thermo-OFF condition even after the compressor frequency decreases, the indoor unit becomes
Thermo-OFF condition. (When Thermo-OFF is activated under this condition, the operation will be restarted after 3 minutes.)
