(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.
2) Detail of operation
(b) Air flow selection
(i) Speed of inverter changes within the range of selected air flow.
(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.
(iii) Cooling “HI POWER” operation (HI POWER button on remote controller: ON)
The unit is operated continuously for 15 minutes regardless of the setting temperature.

Inverter speed 0 rps [Comp. stopped] 10rps [10sec.] → 0rps [Comp. stopped]
Indoor fan Corresponds to fan speed switch.
Outdoor fan Stop 2nd speed [1min.] → stop
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
(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.
Heating oriented dehumidifying Cooling oriented dehumidifying
Low –3 High
Room temperature - Setting temperature (deg)
Cooling or heating oriented dehumidifying is selected again one hour after the first selection of the cooling or heating oriented
dehumidifying.
