1-2. DRY mode of “I FEEL CONTROL”
The system for dry operation uses the same refrigerant circuit as the cooling circuit.
The compressor and the indoor fan are controlled by the room temperature.
NOTE : By such controls, indoor flow amounts will be reduced in order to lower humidity without much room
temperature decrease.
2. Indoor fan speed control
Indoor fan operates at the set speed by FAN SPEED CONTROL button .
In Auto fan speed becomes Low.
3. The operation of the compressor and indoor / outdoor fan
Compressor operates by room temperature control and time control.
Set temperature is controlled to fall 2°C from initial room temperature.
Indoor fan and outdoor fan operate in the same cycle as the compressor.
●
When the room temperature is 23°C or over:
When the thermostat is ON, the compressor repeats 8 minutes ON and 3 minutes OFF.
When the thermostat is OFF, the compressor repeats 4 minutes OFF and 1 minute ON.
●
When the room temperature is under 23°C.
When the thermostat is ON, the compressor repeats 2 minutes ON and 3 minutes OFF.
When the thermostat is OFF, the compressor repeats 4 minutes OFF and 1 minute ON.

4. Coil frost prevention
• The operation is the same as coil frost prevention during COOL mode of “I FEEL CONTROL”.
• Indoor fan operates at the set speed and the compressor stops for 5 minutes because coil frost prevention has priority.
When coil frost prevention works while indoor fan’s stop and compressor’s stop, indoor fan operates at set speed.
②
Time control
When the three conditions as follows have been satisfied for 1 hour and 45 minutes, compressor stops for 3 minutes.
a. Compressor has been continuously operating.
b. Indoor fan speed is Low or Med..
c. Room temperature is below 26°C.
When compressor stops, the value of its duration measure is reset. When it restarts, its duration measure starts all over
again.
Duration measure temporarily stops when the indoor fan speed becomes High or when room temperature exceeds 26
:
.
However, it begins to function again when both conditions above, b. and c. are satisfied.
