1.9 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 the target
temperature 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.

1.10 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 pressing
Econo/Quiet 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. To cancel the
ECONO operation, press
Econo/Quiet button several times until the ECONO symbol
disappears.
 This function and POWERFUL operation cannot be used at the same time. The latest command
has the priority.
