Q How to Approach Test Mode
You can approach the test mode by pressing the on/off switch of
indoor unit for 5 seconds.
Q Test mode operation option
After installing the air conditioner, check whether each subordinate is normally operated or not by operating the test mode.
●When an Error occurs, display the Error Mode.
●Operation Mode : Cool mode. operate the cool mode by operating the compressor by force without the compressor ON/OFF
according to the set temperature/indoor temperature. (Do not follow the antifreeze control)
●Up-down louver : Up-down swing mode
●Indoor Fan : Turbo
● Because the teat 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.
