is above 12°C.
7. Soft Dry Operation Mode
• During Soft Dry Operation, the compressor ON temperature is the setting temperature plus 2°C, the compres-
sor OFF temperature is the setting temperature minus 1°C.
• When the room temperature rises over the compressor ON temperature, the operation mode is switched to the
Cooling mode.
• When the room temperature falls between the compressor ON temperature and OFF temperature, the opera-
tion mode is switched to the Soft Dry Operation.
• The operation diagram is shown below.
