ABSTRACT:
A control device of an air conditioner comprises a first controller which is installed in a room to be air-conditioned and which generates the signals for controlling an air conditioner. A second controller, which is installed in a different room from the room to be air-conditioned also generates signals for controlling the air conditioner. A main controller which receives the signals from the first controller via a first interface and receives the signals from the second controller via second interface, controls the air conditioner in accordance with the two types of signals. The first controller is designed such that once the signal for starting the air conditioning operation of the air conditioner has been sent to the first interface, the first controller sends the signal for running the air conditioner in a predetermined cycle to the first interface until the first controller transmits to the first interface the signal for stopping the operation of the air conditioner. The main controller is designed to invalidate the signal for running the air conditioner, which is received through the first interface, once it has received the signal for stopping the air conditioning operation of the air conditioner from the second controller through the second interface.
