1.9 ECONO Operation
Outline The "ECONO operation" reduces the maximum operating current and the power consumption.
This operation is particularly convenient for energy-saving users. It is also a major bonus for those
whose breaker capacities do not allow the use of multiple electrical devices and air conditioners.
It is easily activated from the wireless remote controller by pushing the ECONO button.
When this function is activated, the maximum capacity also decreases.
The remote controller can send the ECONO command when the unit is in COOL, HEAT, DRY, or
AUTO operation. This function can only be set when the unit is running. Pressing the ON/OFF
button on the remote controller cancels the function.
This function and POWERFUL operation cannot be used at the same time. The latest command
has the priority.
Detail ECONO mode can be activated while the unit is running. The remote controller can send the
ECONO command when the unit is in COOL, HEAT, DRY, or AUTO operation.
When the ECONO command is valid, the power consumption is reduced.
