Abstract

PURPOSE:To provide a controller which can automatically switch between cooling and heating operations to obtain comfortable temperature with one dial position for a cooling and heating conditioner by providing a temperature detector capable of individually discriminating cooling and heating temperature and a fast heat responsive temperature sensor installed in a residence space. CONSTITUTION:A temperature sensor 2 is installed in a residence space. Since air velocity is very low as compared with the conventional air intake port in this cooling and heating conditioner, it employs a fast heat responsive sensor thereat. Since this sensor can set on or off in cooling operation at detected temperatures T1 and T2 and in heating operation at detected temperatures T3 and T4, the same sensor can not only automatically switch between the cooling and the heating operations but obtain comfortable temperature at both cooling and heating time without controlling the dial of a temperature controller.
