Odour Cut Control• Odour cut operation removes the odour generated at indoor heat exchanger by using drain water come out from indoor heatexchanger.• Press “Odour” button at remote control to enable odour cut operation.• Odour cut operation starts when compressor or thermostat is on.9.6.2. Energy Saving• During Operation, press “Economy” button at remote control to enable Energy Saving Operation.• The air conditioner judges the stable condition, where the different between indoor suction temperature and setting temperatureis 1°C for 30 minutes and moderately shifts the set temperature in 0.5°C steps (Maximum 2°C) to control energy savingoperation.• If temperature different is out of range, energy save operation will not start.• Energy Save Operation is canceled by pressing the “Economy” button again.9.6.3. Dew Form Prevention Control• During cooling or soft dry operation, if outdoor temperature is less than 30ºC, and indoor fan speed is low or auto setting, indoorheat exchanger temperature become lower, dew form prevention control start to prevention dew form at indoor discharge grille.• When indoor pipe temperature decrease, the cooling capacity will be reduced and the louver angle will be fixed at certain angle.9.6.4. Freeze Prevention Control• After compressor starts operation for 4 minutes, the outdoor unit will stop its operation if indoor pipe temperature falls below 0ºCfor 6 minutes.• After 3 minutes stops, compressor restarts operation if indoor pipe temperature is 6ºC or more.• This phenomenon is to protect the indoor heat exchanger from freezing and to prevent higher volume of refrigerant in liquid fromreturning to the compressor.9.6.5. Time Delay Safe Control• The compressor will not start for three minutes after stop of operation.9.6.6. Outdoor Fan Remaining Heat Removal Control• When compressor stop, outdoor fan operates at High speed for 1 minute to remove the remaining heat.Thermostat &Compressor ON/OFFThermostat &Compressor ONThermostat &Compressor OFFThermostat &Compressor ONTime 40 sec. 50 sec. - 20 sec. 120 sec. 20 sec. 40 sec. 50 sec. -Cooling Off Lo NormalOperationLo Off Lo Off Lo NormalOperationSoft Dry Off Lo Lo Lo Off Lo Off Lo LoEnergy save control time chart
