by partially separating the electrical circuit of indoor and outdoor units from the power source.
Details Standby electricity saving function can be activated/deactivated from the service mode of
the remote controller.
When standby electricity saving is ON, the system enters suspend state if both indoor and
outdoor units are not in operation.
