7.2 Fuzzy operation for Heating
• According to the setting temperature selected by Fuzzy rule, the operating frequency of compressor is deter-
mined like heating 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 automatically
according to the Fuzzy rule.
• While in Fuzzy operation, the airflow speed of the indoor fan is automatically operated by CHAOS logic.

7.3 Fuzzy operation for dehumidification
• At the beginning of Fuzzy mode operation, the setting temperature is automatically selected according to the
intake air temperature at that time.
• According to the setting temperature selected by Fuzzy rule, the operating frequency of compressor is deter-
mined like dehumidefication mode operation.
