Abstract

PURPOSE:To enable the set temperature to be readily read even under the direct sunlight in an air conditiner wherein temperature displaying elements are radiated and displayed by time-sharing, by irradiating and driving the set temperature displaying elements for a certain period from the set change longer than others. CONSTITUTION:In a microcomputer, a series of control programs are executed and processed every 10ms, and by the interruption of a timer 2e the set temperature data is read out from an RAM2c to be gived to a seven-segment type display element 6a, and the interior temperature data and exterior temperature data are provided to the display elements 6b, 6c to be rediated and displayed. When temperature setting switches 5a, 5b are operated, the period of the radiation of the display element 6a after the operation is made longer than other display element. Since the brightness of this display element is proportional to the period of the radiation, the set temperature is irradiated and displayed with enough brightness for a certain period after the change.
