1.8 NIGHT SET Mode
Outline When the OFF TIMER is set, NIGHT SET Mode is automatically activated. NIGHT SET Mode
keeps the airflow rate setting.
Detail NIGHT SET Mode continues operation at the target temperature for the first one hour, then
automatically raises the target temperature slightly in cooling, or lowers it slightly in heating. This
prevents excessive cooling or heating to ensure comfortable sleeping conditions, and also
conserves electricity.

1.9 ECONO Operation
Outline ECONO operation reduces the maximum operating current and the power consumption. This
operation is particularly convenient for energy-saving. It is also a major bonus when breaker
capacity does not allow the use of multiple electrical devices and air conditioners.
It can be easily activated by pushing the ECONO button on the wireless remote controller.

button on the remote controller to cancel the function.
