•Controlling operation in case when thermostat of remote controller works is same as a case when thermostat of the body works.

•If the fan speed has been changed once, it is not changed for 3 minutes. However when the air volume is exchanged, the fan speed changes.

•When cooling operation has started, select a downward slope for the fan speed, that is, the high position.

•If the temperature is just on the difference boundary, the fan speed does not change.

•Mode in the parentheses indicates one in automatic cooling operation.
