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 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 pushing the
ECONO
button on the wireless remote controller.
Detail

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 the
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.
