For this multi-zone air conditioning system, the outdoor unit is able to drive up to five indoor units which can be
different types as shown above. The console indoor unit can be controlled only by the remote control. The
other indoor units can be controlled by either the remote control or the wall control. The outdoor unit will run if
any of the indoor units sends a request for heating or cooling. All indoor units will stop once the outdoor unit is
turned off.
