PURPOSE:To simplify the operation when a plurality of indoor units are divided by connecting the control for other room separated by a partition to the control section for other room which is wired to the main unit control section and is disposed on the wall, and providing said control section for other room with control switches and LED display of operating condition of air conditioner. CONSTITUTION:A partition 26 is erected to partition the A room from the B room. An indoor unit 20 conditions the A room, and an indoor unit 19 conditions the B room. In the A room, the air conditioning is performed by operating the main unit control section 25. Meanwhile, in the B room where the air conditioning is not required, the indoor unit 19 is stopped by opening the operation switch 30 for this room, and, at the same time, an 'L' level potential is outputted from the I/O terminal A. Then, the potential at the B point becomes 'H' level via a driver IC33, and an LED31 goes off due to the fact that said 'H' level potential becomes equal to that of the power source 29 to denote that the air conditioning is being stopped. |
