Test Mode Operation Option

Afterinstallingtheairconditioner,checkwhethereachsubordinateisnormallyoperatedornotbyoperatingtheTestMode.

•When an error occurs, display the Error Mode.

•Operation Mode : Coolmode.OperatethecoolmodebyoperatingthecompressorbyforcewithoutthecompressorON/OFF accordingtothesettemperature/indoortemperature.(Donotfollowtheantifreezecontrol)

•Up-down louver : Up-downswingmode

•Indoor Fan : High

•Because the Test Mode operate the cool mode by force not related to the set temperature / indoor temperature, check whether each subordinate is operated normally or not after completing installation and must turn off the power of the air conditioner.
