*1: Auto restart is an emergency function such as for power failure etc.
Do not start and stop the indoor unit by this function in normal operation.
Be sure to operate by the control unit, converter or external input device.
*2: Inappropriate setting may cause an external device malfunction. Confirm whether all
the settings have been performed appropriately according to the installing condition.
*3: Function number 68 and 69 will be usable provided that the corresponding operating
device is connected.
*4: When using function number 75, inappropriate heater selection may cause cold air in
defrosting.
