CS-MVG103KE / CU-MVG153KE

8.2. TEMPERATURE SHIFT
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:
8.2.1. Table a
Setting Temperature Shift based on outdoor air temperature.

8.4. COOLING OPERATION
8.4.1. Room Temperature Control
1.When the remote control setting temperature is less than 24°C.
Refer to8.3.2. Compressor Operation Frequency
2.When the remote control setting temperature is 24°C and above.
Refer to8.3.1. Compressor Operation Frequency
· Thermostat OFF temperature = Thermostat ON temperature.
· The Comp. Operation Frequency Command can be changed every 30 seconds.
· 30 minutes from the start of the operation, the compressor is operating at Fc max.
· The Thermostat OFF when the intake air temperature reaches 1°C below internal setting temperature and continues for 3
minutes.
· When the Thermostat of both Indoor Units OFF, the Compressor stops.
· 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.

8.4.2. 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 Thermostat ON operation, the deodorizing status starts from 1 →2→3.
· When the Thermostat OFF operation, the deodorizing status starts from 4 →5→6→7.
· If the Thermostat OFF operation after 3 minutes, the deodorizing status will start from 6.
8.4.3. Sensible Heat Control
· This control is to improve the feeling in high fan speed during low Comp. Operation Frequency Command Number. When the
Comp. Operation Frequency Command Number is less than 4, the fan speed will reduce. When the Comp. Operation
Frequency Command Number is above 5 continuously for 5 minutes, the fan speed will resume to normal condition.

8.5. SOFT DRY OPERATION
8.5.1. Room Temperature Control
At the start of operation, cooling operation is running until the intake air temperature is 0.5°C higher than internal setting
temperature, then the operation will shift to Soft Dry with indoor fan speed SLo.
Refer to8.3.1. Compressor Operation Frequency
· Thermostat OFF temperature = Thermostat ON temperature.
· The Comp. Operation Frequency Command can be changed every 30 seconds.
· 30 minutes from the start of the operation, the compressor is operating at Fc max.
· The Thermostat OFF when the intake air temperature reaches 1°C below internal setting temperature and continues for 3
minutes.
· When the Thermostat of both Indoor Units OFF, the Compressor stops.
· When the compressor stops, it will not begin operation for 3 minutes. (Time Delay Safety Control)
