Abstract
Disclosed is a temperature control system for airconditioners having air blend doors which are controlled by electrical signals related to the room temperature such that the amount of cool air to be reheated by a heater and the amount of cool air bypassing the heater have an appropriate proportion so as to achieve a desired room temperature, and a sensor which provides an electrical signal representing the degree of opening of the air blend door. The degree of opening of the air blend door is recognized with reference to the electrical signal from the sensor corresponding to the full-closed position or full-open position of the air blend door. The system has a function of zero-adjusting the sensor automatically following the control operation.
