ABSTRACT:
A control device for an air conditioner operable in the heating and cooling operation mode is disclosed, which device comprises a "too hot" and a "too cold" switch which is operated by the user when he feels that it is too hot or too cold in the room conditioned by the air conditioner. When a first operation of one of these switches by the user takes place, a mode selector automatically selects the operation mode of the air conditioner, and the control of the air conditioner is started immediately. The setting or target temperature is automatically renewed every time a further operation of one of the switches is made, so that the target temperature may be adjusted to the individual preference of the user. The fan speed of the air conditioner may also be modified according to the frequency of inputs through the switches.
