About ECONOMY Operation
● When ECONOMY operation mode is operated, the room temperature will be little higher than the set-temp under cooling mode
and lower than set-temp under heating mode. Therefore, the ECONOMY mode is able to save more energy than other normal
mode.
● In case of single-type, at the maximum output, ECONOMY Operation is approximately 70% of normal air conditioner operation for
cooling and heating.
● In case of multi-type air conditioner, the ECONOMY operation mode is only available for the set indoor unit.
● If the room is not cooled (or heated) well during ECONOMY operation, select normal operation.
● During the monitor period in the AUTO mode, the air conditioner operation will not change to ECONOMY operation even if ECON-
OMY operation is selected by pressing the ECONOMY operation button.

About the 10°C 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.
