(b) When the protection device is actuated, operation is performed in the corresponding mode.
(c) Outdoor fan operates in accordance with the instruction frequency.
(3) Details of control in each operating mode
(a) Fuzzy operation
Deviation between the room temperature setting compensation value and the suction air
temperature is calculated in accordance with the fuzzy rule, and used for control of the air
flow and the inverter frequency.
(b) Cooling constant temperature operation
● Operating conditions
If the frequency obtained with the fuzzy calculation drops below -24 rps during the
cooling fuzzy operation, the operation changes to the cooling constant temperature
operation.
