(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 inverter command speed.
(c) Detail of control in each mode (Pattern)
(i) Fuzzy operation
During the fuzzy operation, the air flow and the inverter speed 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 speed obtained by the fuzzy calculation is less than -24 rps.

(8) 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.
