Cooling “
”, can be set. When the indoor unit outlet air temperature falls at cooling operation, the
compressor frequency forcibly decreases to prevent a drop in outlet air temperature. If the outlet
temperature decreases and the temperature is less than the 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 three minutes.)
