The ECONOMY operation functions by pressing ECONOMY button on the remote controller.
At the maximum output, ECONOMY Operation is approximately 70% of normal air conditioner operation
for cooling and heating.
The ECONOMY operation is almost the same operation as below settings.

The HUMAN SENSOR functions by pressing SENSOR button on the remote controller.
When the sensor detects that there is no one in the room for 20 minutes or more,

( Application range )
The sensor unit should detect when the human body (estimate: 100cmX30cm) or the object
which has more than 4 degreesC temp, difference from the background and are crossed with
1.0m/s speed in front of the sensor unit.
When the outdoor heat exchanger temperature is lower than 5°C and the all operation has
been stopped for 30 minutes, power is applied to the compressor and the compressor is heated.
(By heating the compressor, warm air is quickly discharged when operation is started.)
When operation was started, and when the outdoor heat exchanger temperature rises to 7°C or greater,
preheating is ended.
