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 (refer Table b)
+
Any Sleep Mode shift operation?
+
Any Powerful Operation shift? (refer Table c)
+
[Check upper/lower (33°C/16°C) limit for setting temperature]

• 30 minutes from the start of the operation, the compressor is operating at Fc max Hz.
• Thecompressorstops when theintakeairtemperature reaches1°Cbelowinternalsetting temperature andcontinuesfor
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.

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 40Hz (CU-G90KE) or 43HZ (CU-G120KE), the fan speed will reduce. When the
operationfrequencyisabove33Hzcontinuouslyfor5minutes,thefanspeedwillresumetonormalcondition.

Operation Details
• Compressor OFF temperature = compressor ON temperature.
• The operation frequency changes every 30 seconds.
• When the difference of the intake air temperature and Internal setting temperature is –1.5°C or more, compressor will operate at Fh
continuously for 3 minutes and then change over to Fhmax.
• Thecompressorstopswhentheintakeairtemperaturereaches1.5°Caboveinternalsettingtemperatureandcontinuesfor3minutes.
• When the compressor stops, it will not start operation for 3 minutes. (Time Delay Safety Control)
• When the intake air temperature decreases to the compressor ON temperature, the compressor starts immediately.
