PURPOSE:To improve certainty of operation in an air conditioner having an operation mode display part by so constructing that completion of operation mode switching is judged and incompletion is warned by means of operation sensors installed at prescribed locations in an actuator. CONSTITUTION:When operation commands from operation mode changing switches 30 and 31 are inputted into a control 4, the control 4 actuates open-shut flaps 12, 2, 3 and 24 by driving actuators 46, 48 and 49 in accordance with a prescribed program. Following this open-shut operation, potentiometers 50, 52 and 53 move and the detected potentials are fed back to the control 4 at prescribed timing. When the potentials detected with the potentiometers 50, 52 and 53 do not reach a criterion in a prescribed period of time, e.g. 3sec, the control 4 determines the operation as incomplete and, after making the display part 28 to blink, puts out the light. Certainty of operation can be secured and improved with this construction. |
