(2) Since the ON timer, Sleep timerandOFFtimeraresetinparallel,whenthetimestoturnONandOFF theair-conditionerareduplicated,the
settingoftheOFFtimerhaspriority.
(5) Hot start (Cold draft prevention at heating)
(a) Operating conditions
Wheneitheroneoffollowingconditionsissatised,thehotstartcontrolisperformed.
(i)Fromstoptoheatingoperation
(ii)Fromcoolingtoheatingoperation
(iii)FormheatingthermostatOFFtoON
(iv)Aftercompletingthedefrostoperation(onlyonunitswiththermostatON)
(b) Contents of operation
(i) Indoor fan motor control at hot start
1) Within7 minutesafterstartingheatingoperation,thefanmodeis determineddepending ontheconditionof
thermostat(fancontrolwithheatingthermostatOFF).
a)ThermostatOFF
i)OperatesaccordingtothefancontrolsettingatheatingthermostatOFF.
ii)EvenifitchangesfromthermostatOFFtoON,thefancontinuestooperatewiththefancontrolatthermostat
OFFtilltheheatexchangertemperaturesensor(Thi-R1orR2,whicheverhigher)detects35°Corhigher.
iii)Whentheheatexchangertemperaturesensor(Thi-R1orR2,whicheverhigher)detects35°Corhigher,thefan
operateswiththesetairowvolume.
b) Thermostat ON
i)Whentheheatexchangertemperaturesensor(Thi-R1orR2,whicheverhigher)detects25°Corlower,thefanis
turnedOFFanddoesnotoperate.
ii)Whentheheatexchangertemperaturesensor(Thi-R1orR2,whicheverhigher)detects25°Corhigher,thefan
operateswiththefancontrolatheatingthermostatOFF.
iii)Whentheheatexchangertemperaturesensor(Thi-R1orR2,whicheverhigher)detects35°Corhigher,thefan
operateswiththesetairowvolume.
c)IfthefancontrolatheatingthermostatOFFissetatthe“Setairowvolume”(fromtheremotecontrol),thefan
operateswiththesetairowvolumeregardlessofthethermostatON/OFF.
2)OncethefanmotorischangedfromOFFtoONduringthethermostatON,theindoorfanmotorisnotturnedOFF
eveniftheheatexchangertemperaturesensordetectslowerthan25°C.
Note(1)Whenthedefrostcontrolsignalisreceived,itcomplieswiththefancontrolduringdefrostoperation.
3)Oncethehotstartiscompleted,itwillnotrestartevenifthetemperatureontheheatexchangertemperaturesensor
drops.
(ii)Duringthehotstart,thelouveriskeptatthehorizontalposition.
(iii)WhenthefanmotoristurnedOFFfor7minutescontinuouslyafterdefrostoperation,thefanmotoristurnedONre-
gardlessofthetemperaturesdetectedwiththeindoorheatexchangertemperaturesensors(Thi-R1,R2).
(c) Ending condition
(i)Ifoneoffollowingconditionsissatisedduringthehotstartcontrol,thiscontrolisterminated,andthefanisoperated
withthesetairowvolume.
1)Heatexchangertemperaturesensor(Thi-R1orR2,whicheverhigher)detects35°Corhigher.
2)Ithaselapsed7minutesafterstartingthehotstartcontrol.
