: Sends the fresh air as it is
• The air conditioner with the fresh air intake unit controls temperature of the supply air so that it is close to
the setup temperature of the remote controller.
However temperature of the supply air may not be close to the setup temperature according to tempera-
ture of the fresh air or the operation condition of the indoor units for air conditioning in one line.
• The air conditioner with the fresh air intake unit cannot control the room temperature.
• For control of the room temperature, an indoor unit for air conditioning is required separately.
