- Hot start function heat pump only 48
- In order to prevent the cold air blast that normally comes when heating is started the temperature of the heat exchanger of the indoor unit is detected and either the air flow is stopped or is made very weak thereby carrying out comfortable heating of the room the cold air blast is also prevented using a similar control when the defrosting operation is started or when the thermostat gets turned on during defrosting or when the thermostat is on in heating mode the indoor heat exchanger temperature 29 c to fan starts to avoid cold draft 48

- Program dry function 48
- Program dry function removes humidity while preventing the room temperature from lowering since the microcomputer controls both the temperature and air flow volume the temperature adjustment and fan adjustment buttons are inoperable in this mode 48
- The microcomputer automatically sets the temperature and fan settings the difference between the room temperature at startup and the temperature set by the microcomputer is divided into two zones then the unit operates in the dry mode with an appropriate capacity for each zone to maintain the temperature and humidity at a comfortable level 48
- When the equipment has been stopped the compressor is warmed up by passing a small single phasing current through the compressor motor so that the start up is speeded up 2 the power consumption during warming up is about 15 to 35w 3 this function operates only when the outside temperature is low less than about 10ºc so that power saving is achieved 48

- Sie00 04 main functions 51
- Since the set temperature is shifted by 2 c higher for 40 minutes compressor speed becomes low and can realize energy saving operation but as thermostat is prone to be off by the fact that the set temperature has been shifted the thermostat off action is prohibited in 40 minutes so as to prevent this phenomena after this 40 minutes the prohibition of the thermostat off is cancelled and it can realize the conditions to conduct thermostat off depending on the room temperature in or after this forty minutes if the sensor detects human motion detection signal it turns on human detection led and let the set temperature and the fan speed return to the original set point keeping a normal operation 51
- The dry operation can t command the setting temperature with a remote control but internally the set temperature is shifted by 1 c 51
- The motions for example in cooling 51
- When a micro computer doesn t have a signal from the sensor in 20 minutes it judges that no body is in the room and turns off the human detection led operating the unit in temperature sifted 2 c from the set temperature cooling 2 c higher dry 1 c higher and auto according to the operation mode at that time 1 in case of fan mode the fan speed reduces by 50 rpm 51

- Main functions sie00 04 52
- Notes 1 each timer s counting stop is not related to a thermostat on off 2 when the sleeping control works by the off timer the shift from the set temperature should be just 1 c with this control function the temperature shift of the normal off timer will not be carried out however the passed time should be remembered since the off timer was set 3 while operation with the good sleep cooling control and off timer setting if the signal of the good sleep cooling off signal comes the level of the set temperature shift should be set corresponding to the same with an existing value in accordance with the passed time since the off timer was set 4 when the good sleep cooling control is on while a normal operation with a off timer is going on once returning to the original criterion which doesn t shift the timer s set temperature and the shift alteration at every sequence by 1 c is carried out in accordance with the value above mentioned 5 fan speed will change by the alteration of the set temp 52
- Processing 52
- The function to create deep sleeping and to offer good sleep by altering the set tempeatures in certain intervals to give temperature variation to a living space based on 1 f temperature fluctuation principle in case of going to bed while air conditioner keeps operating in cooling mode 52
