• The outing control only starts/stops the air conditioner. It does not change the
operation mode/temperature setting.
Therefore, the operation mode/temperature needs to be set beforehand so that
the outing function turns on the air conditioner with your desired operation mode/
temperature setting.
• If the room temperature rapidly changes, the room temperature may get over the
upper or lower limit when the outing function is activated.
• The outing function is invalid during FAN/AUTO operation mode.
• The air conditioner’s stop order (stated in 2/ above) is valid only when the outing
function is operated.
If operated using other remote control unit (or a centralized control device such as a
