8 Operation Details
8.1. Function
Once the operation stars, 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:
Table a
Setting Temperature Shift based on outdoor air temperature.
Table b
Powerful Mode Shift.

S-G95KE CU-G95KE / CS-G125KE CU-G125KE

2. Cooling Operation
A. Room Temperature Control
(i) When the remote control setting temperature is less than 24°C
(ii) When the remote control setting temperature is 24°C and above
• 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.
19
CS-G95KE CU-G95KE / CS-G125KE CU-G125KE

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-G95KE) or 36Hz (CU-G125KE), the fan speed will reduce. When the operation frequency is increased to
40Hz (CU-G95KE) or 49Hz (CU-G125KE) continuously for 5 minutes, the fan speed will resume to normal condition.
