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.
