Note for Multi System
Multisystemhasoneoutdoorunitconnectedtomultipleindoorunits.
■
Selecting the operation mode
With the priority room setting present but
inactive or not present.
Whenmorethanoneindoorunitisoperating,priorityisgivento
therstunitthatwasturnedon.
Inthiscase,settheunitsthatareturnedonlatertothesame
operationmodeastherstunit.
Otherwise,theywillenterthestandbystate,andtheOPERATION
lampwillash:thisdoesnotindicatemalfunction.
NOTE

Notes on operation mode for multi system
• COOL,DRYandFANoperationmaybeusedatthesametime.
• AUTOoperationautomaticallyselectsCOOLoperationorHEAToperationbasedontheroomtemperature.
Therefore,AUTOoperationisavailablewhenselectingthesameoperationmodeasthatoftheroomwiththerstunittobeturnedon.
CAUTION
• Normally,theoperationmodeintheroomwheretheunitisrstrunisgivenpriority,butthefollowingsituationsareexceptions,sopleasekeep
thisinmind.
IftheoperationmodeoftherstroomisFANoperation,thenusingHEAToperationinanyroomafterthiswillgiveprioritytoHEAToperation.In
thissituation,theairconditionerrunninginFANoperationwillgoonstandby,andtheOPERATIONlampwillash.
With the priority room setting active.
Refertopriorityroomsettingonthenextpage.

NIGHT QUIET mode (Available only for COOL operation)
NIGHTQUIETmoderequiresinitialprogrammingduringinstallation.Pleaseconsultyourretailerordealerforassistance.
NIGHTQUIETmodereducestheoperationnoiseoftheoutdoorunitduringthenighttimehourstopreventannoyanceto
neighbors.
• TheNIGHTQUIETmodeisactivatedwhenthetemperaturedrops5°Cormorebelowthehighesttemperaturerecordedthatday.Therefore,
whenthetemperaturedifferenceislessthan5°C,thisfunctionwillnotbeactivated.
• NIGHTQUIETmodereducesslightlythecoolingefciencyoftheunit.

With the priority room setting present but inactive or not present.
WhenusingtheOUTDOORUNITQUIEToperationfeaturewiththemultisystem,setallindoorunitstoOUTDOORUNIT
QUIEToperationusingtheirremotecontrollers.
WhenclearingOUTDOORUNITQUIEToperation,clearoneoftheoperatingindoorunitsusingtheirremotecontroller.
HoweverOUTDOORUNITQUIEToperationdisplayremainsontheremotecontrollerforotherrooms.
Werecommendyoureleaseallroomsusingtheirremotecontrollers.
