2-2 DRY operation
On the switch on, the compressor always starts
to operate for 2 minutes with fan speed "DL" .
The microcomputer reads the room temperature
2 minutes after this first compressor operation.
This room temperature is set as the preset
temperature automatically.
The preset temperature ranges from 18˚C to
32˚C. When the room temperature is below
18˚C, the preset temperature is set to 18˚C,
and when the room temperature is over 32˚C,
the preset temperature is set to 32˚C.
Dry operation is divided into three zones
(Cooling zone, Dehumidifying zone and
Circulating zone) by thermostat lines (D1 to
D3), and the compressor and the fan motor
are controlled in each zone as shown in Table
Y-1.
States 1 & 5 : Cooling zone
States 2 & 4 : Dehumidifying zone
States 3 : Circulating zone
