1.4 Programme Dry Function
By the function of the microcomputer, programme dry operation reduces the humidity keeping
the temperature in a minimum drop. Room temperature and air flow rate can not be controlled
by the adjusting buttons because they are controlled automatically. When the program dry
function starts, dry operation is provided, and then it repeats 5-minute suspension and 4-minute
dry operation alternately. When the room temperature rises, it repeats the above process from
the beginning.
∗1 Dry operation activating (compressor ON) temperature
∗2 Room temperature difference between activation and suspension of dry operation
Note: 1. The programme dry function is not operated when the room temperature is at 18°C or less.
2. In monitoring operation, fan rotates 5 seconds after the compressor starts its operation.
