Page 88 Operation operates with the low or setting speed. When the indoor pipe temp is between 20°C and 27°C, it operates with Super-Low(while in sleep mode, with the medium airflow speed). • While compressor off, the indoor fan is off when the indoor pipe temp is below 33°C, when above 35°C , it operates with the low airflow speed.
Page 89 Operation 2) Fuzzy Operation for Dehumidification • According to the setting temperature selected by Fuzzy rule, when the intake air temp is 0.5°C or more below the setting temp, the compressor is turned off. When 0.5°C or more above the setting temp, the compressor is turned on.
Page 90: Sleep Timer Operation
Operation Off-Timer <=> On-Timer Operation • When the set time is reached after the on/off time is input by the remote control, the on/off-timer operation is carried out according to the set time. Sleep Timer Operation • When the sleep time is reached after <1,2,3,4,5,6,7,0(cancel) hr> is input by the remote control while in appli- ance operation, the operation of the appliance stops.
Page 91: Forced Operation
Operation Forced Operation • To operate the appliance by force in case that the remote control is lost, the forced operation selection switch is on the main unit of the appliance to operate the appliance in the standard conditions. • When the power is supplied while the slide switch is on the forced operation position, or when the slide switch position is switched to the Auto Restarting (or test operation) position or switched from the remote control position to the forced operation position while the power is on, the forced operation is carried out.
