(3) Details of control at each operation mode (pattern)
(a) Fuzzy operation
Deviation between the room temperature setting correction temperature and the suction air temperature is calculated in
accordance with the fuzzy rule, and used for control of the air capacity and the inverter command speed.
(b) Heating thermostat operation
¡ Operating conditions
If the inverter command speed obtained with the fuzzy calculation drops below -24 rps during the heating fuzzy operation,
the operation changes to the heating thermostat operation.
¡ Detail of operation
