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 air conditioner, at the maximum output, ECONOMY operation is approximately 70% of normal air condi-
tioner 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.
