•Once the setting is made, the operation mode is memorized in the microcomputer so that the same operation can be effected thereafter simply by pushing [START/STOP] button.

•Dry operation signal is transmitted to outdoor unit.

•The Cooling operation giving priority to dehumidi- fying, which restrains the indoor fan speed and compressor motor speed, is performed.

•The indoor fan motor operates as shown in Fig. 8-2-5. (Fan speed is AUTO only.)

•The outdoor unit controls the outdoor fan relay R01, R02 and R03, and the compressor motor speed according to the operation command signal sent from the indoor unit.
