Once the operation starts, the remote control setting temperature will be shifted internally based on the setting fan
speed and outdoor air temperature. In addition, if Sleep Mode or Powerful Mode are set, the temperature shift will
be carried out.
Setting of Internal Setting Temperature
The internal setting temperature can be decided as follows:
Remote control setting temperature
+
Outdoor temperature shift (refer Table a)
+
Fan speed shift (+ 1.0 °C)
+
Any Sleep Mode shift operation?
+
Any Powerful Operation shift? (refer Table b)
+
[Check upper/lower (33°C/16°C) limit for setting temperature]

• Compressor OFF temperature = Compressor ON temperature.
• The operation frequency can be changed every 30 seconds.
• 30 minutes from the start of the operation, the compressor is operating at Fc max Hz.
• The compressor stops when the intake air temperature reaches 1°C below internal setting temperature and
continues for 3 minutes.
• When the compressor stops, it will not begin operation for 3 minutes. (Time Delay Safety Control)
• When the intake air temperature reaches the Compressor ON temperature, the Compressor starts operation.
• When the compressor stops, the outdoor fan motor stops 30 seconds later.

Operation Details
B. Deodorizing Control
• This control is available during automatic fan speed for Cooling and Soft Dry Operation. It is not available
during anti-freezing control.
• When the compressor is in operation, the deodorizing status starts from 1 →2 →3.
• When the compressor stops operation, the deodorizing status starts from 4 →5 →6 →7.
• If the compressor still stops operation after 3 minutes, the deodorizing status will start from 6.
C. Sensible Heat Control
• This control is to improve the feeling in high fan speed during low operation frequency. When the operation
frequency is less than 33Hz (CU-G93KE) or 36Hz (CU-G123KE), the fan speed will reduce. When the
operation frequency is increased to 40Hz (CU-G93KE) or 49Hz (CU-G123KE) continuously for 5 minutes,
the fan speed will resume to normal condition.

4. HEATING OPERATION
A. Room Temperature Control
• During heating operation, the room temperature control depends on intake air temperature and internal
setting temperature. Basically it can be divided into 2 periods as shown below:
