1. Temperature control characteristic
1-1 COOL operation
In the “COOL” mode, the thermostat circuit is
controlled by four thermostat lines (C1 thru C4).
Figure H-3
2-2 DRY operation
On the switch on, the compressor always starts
to operate for 2 minutes with fan speed “D”
(slower than “UL”).
The microcomputer measures 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
H-1.
