1. INDOOR UNIT
1-1 Temperature Adjustment
(1) Cooling
When the room temperature is higher than the preset
temperature by 2˚Cor more, the unit runs at the
maximum operation frequency until the temperature
comes down to the preset temperature.
When reaching the preset temperature, the unit
runs at the frequency calculated by the fuzzy
operation and switches to the normal control.
(2) Dry
After operation begins, 2 minutes of the room
temperature is stored in memory, and that becomes
the set value.
1-2 Indoor fan control
The fan speed can be selected from "Auto", "Soft",
"Low",and "HIgh".When "Soft", "Low" or "HIgh" is
selected, the fanspeed is constant regardless of the
room temperature.When "Auto" is selected, the fan
speed automatically changes between "Soft" and
"HIgh" depending on the difference
between the room and preset temperature.
Control for indoor freezing prevention
If the temperature of the indoor heat exchanger stays
below approximately 1˚C for four minutes during
cooling or dry, this control stops the compressor.
Over 3˚C the compressor will run again.
1-3 Automatic operation
The operating mode and temperature setting are
determined by the room temperature and the external
air temperature.
The operating mode will changeover automatically
with the following condition.
When the set temperature is adjusted within the
range of ±2˚C by the remote control's key. (
