PURPOSE: To obtain an indoor comfortable temperature and to provide an energy conservation by adding or subtracting a predetermined deviation temperature to or from the atmospheric temperature, and selecting the set temperature by the specified temperature or calculated temperature by the comparison of the value with the specified temperature when the calculated value is selected by the comparison of the atmospheric temperature with a limit temperature. CONSTITUTION: An adding or subtracting processor 13 subtracts a deviation temperature from the atmospheric temperature input via an analog input unit 11 in summer, or adds the deviation temperature in winter. A comparator 14 compares the atmospheric temperature with the limit temperature, and the compared result of the added or subtracted value of the processor 13 with the specified value is output to a selector 15. The selector 15 outputs the specified temperature as a set temperature if it does not satisfy the condition of the limit temperature by the comparison of the atmospheric temperature with the limit temperature by the comparator 14. The selector 15 outputs the added or subtracted value as the set temperature if the added or subtracted value satisfies the condition of the specified temperature by the comparison of the added or subtracted value with the specified value by the comparator 14. |
