Operation

Fuzzymodeoperation(Optional)s

•When any of operation mode is not selected like the moment of the power on or when the unit turned off, the operation mode is selected.

•When determining the operation mode, the compressor, outdoor fan are off and only the indoor fan is operat- ed for 15~20 seconds, then an operation mode is selected according to.

Basis of determining operating mode

over 24°C	Cooling

below 21°C	Heating

1.Fuzzy operation for cooling

•According to the setting temperature selected by Fuzzy rule, the operating frequency of compressor is deter- mined like cooling mode operation.

•At the beginning of Fuzzy mode operation, the setting temperature is automatically selected according to the intake air temperature at that time.

•When the Fuzzy key(=setting temp. key) is input after the initial setting temperature is selected, the Fuzzy key value and intake air temperature at that time are compared to select the setting temperature automatical- ly according to the fuzzy rule.

•While in Fuzzy operation, the air flow speed of the indoor fan is automatically operated by Fuzzy logic.
