Outline
This function is to save standby electricity consumption while the air conditioner is not in operation
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.
The system will not go into suspend state when some voltage is applied to the outdoor unit
for protection purpose even if the indoor unit is not in operation.
In suspend state, power supply to the outdoor unit is halted and there is no communication
between the indoor unit and the outdoor unit.
