About the
HEAT Operation
• The Heating mode will not operate if the room temperature is high enough.
• The room temperature can be maintained at 10 °C by pressing the 10 °C HEAT button
so as to prevent the room temperature from falling too far.
• In case of multi-type air conditioner, if other indoor unit is used for heating, the temper-
ature of the room where the "10°C HEAT" function is applied will rise. When using the
"10°C HEAT" function, we recommend all indoor units should be run under the"10°C
HEAT" mode.
