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 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 Inverter POWERFUL operation cannot be used at the same time. The latest
command has the priority.
7.9 HOME LEAVE Operation

Outline HOME LEAVE operation is a function that allows you to record your preferred set temperature and
airflow rate. You can start your preferred operation mode simply by pressing HOME LEAVE button
on the remote controller.
Details The indoor unit is operated according to the set temperature and airflow rate for HOME LEAVE
which were preset in the memory of the remote controller.
Start of Function
The function starts when HOME LEAVE button is pressed in cooling operation, heating operation
(including POWERFUL operation), or while the operation is stopped.
A mark representing HOME LEAVE is indicated on the display of the remote controller, and the
LED (red) of indoor unit representing HOME LEAVE lights up. (It goes out when the operation is
