PURPOSE:To operate the air conditioners in accordance with a condition that the last regulated state is held and improve the operability of a system by a method wherein a signal is outputted to an operation stop control circuit only when a control signal does not coincide in logic with a condition signal within a predetermined time period from a time when the control signal is changed from operation to stop or from stop to operation. CONSTITUTION:The device is constituted of the operation stop control circuit 19, provided with the same signal as the operation effected by the non-lock type operation stop switch of the air conditioner, a condition detecting circuit 22, detecting the stop condition of operation of the air conditioner, a condition signal output circuit 26, outputting the condtion signal of the condition detecting circuit 22 to a central control unit, a control signal input circuit 28, inputting the control signal for operating or stopping the operation of the air conditioner from the central contrl unit, and a control pulse generating circuit 31, generating a predetermined pulse signal to output it to the operation stop control circuit only when the control signal is changed and the logic of the control signal does not coincide with the logic of the condition signal within a predetermined time period. According to this method, the condition of the system is brought into a condition that the last regulated state is held, therefore, the operability of the system may be improved. |
