[. . . ] Normal operation begins. About ECONOMY Operation At the maximum output, ECONOMY Operation is approximately 70% of normal air conditioner operation for cooling and heating. When ECONOMY operation is performed during the cooling mode, dehumidification is improved. This function is especially convenient when you want to remove the humidity in the room without significantly lowering the room temperature. During ECONOMY operation, the thermostat setting automatically changes according to the temperature to avoid Unnecessary cooling and heating for the most economical operation. If the room is not cooled(or heated) well during economy operation, select normal operation. Once air conditioner operation is stopped, normal operation begins when the indoor unit is turned on again. During the monitor period in the AUTO mode, the air conditioner operation will not change to ECONOMY operation even if ECONOMY operation is selected by pressing the ECONOMY operation button.
