(ii) When any protective function actuates, the operation is performed in the mode corresponding to the function.
(iii) Outdoor blower is operated in accordance with the frequency.
(b) Detail of control in each mode (Pattern)
(i) Fuzzy operation
During the fuzzy operation, the air flow and the inverter frequency are controlled by calculating the difference between
the room temperature setting correction temperature and the suction air temperature.
(ii) Cooling thermostat operation
1) Operating conditions
During the cooling fuzzy operation or when the frequency obtained by the fuzzy calculation is less than -24 Hz.

Notes (1) In the continuous mode, the unit is operated with the continuous cooling operation without adjustment of room temperature.
(2) Protective functions will actuate with priority even during the continuous mode operation.
(iv) Cooling "HI POWER" operation (HI POWER button on remote controller: ON)
The unit is operated continuously for 15 minutes regardless of the setting temperature.
1) Detail of operation: Following cycle is repeated 3 times.

Notes (1) Protective functions will actuate with priority even during the "HI POWER" operation.
(2) Room temperature is not adjusted during the "HI POWER" operation
(3) "HI POWER" operation is prohibited during the operation controlled with the pleasant reservation timer.
(7) Outline of dehumidifying operation
(a) After operating the indoor blower for 20 seconds from immediately after the start of operation, the indoor temperature is
checked and, based on the result of check, the cooling oriented dehumidifying or heating oriented dehumidifying is selected.
Cooling or heating oriented dehumidifying is selected again one hour after the first selection of the cooling or heating oriented dehumidifying.
