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.
Details 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.

1.9 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 pressing ECONO button on the wireless remote controller.
Details

When this function is activated, the maximum capacity also decreases.

The remote controller can send the ECONO command when the unit is in cooling, heating, dry,
or automatic operation. This function can only be set when the unit is running. Press ON/OFF
button on the remote controller to cancel the function.

This function and POWERFUL operation cannot be used at the same time. The latest command
has the priority.
