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 the case of cooling, or lowers it slightly in the
case of heating. This prevents excessive cooling in summer and excessive heating in winter to
ensure comfortable sleeping conditions, and also conserves electricity.

ECONO Operation

Outline ECONO operation reduces the maximum 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.
