Abstract
An automatic air conditioner is arranged to be responsive to external air temperature in a manner wherein, if the atutomatic mode is interrupted and manual control instigated and the external temperature is low (viz., below a predetermined level), the mode to which the system defaults upon the automatic - manual change, is set to defrost, defrost/foot modes or the like. On the other hand, if the external temperature is high (viz., above the predetermined level) the system is conditioned to default to the vent mode.
