ABSTRACT:
A room temperature controlling apparatus used for an air conditioner includes a thermistor for detecting the temperature in a room, a variable resistor for setting a reference temperature for said room, a pyroelectric infrared sensor for detecting movement of a person in said room and outputting signals representative of the detection of the movement of said person, a room temperature modification circuit for modifying the room temperature detected by said thermistor based on the signals transferred from said pyroelectric infrared sensor, and a comparator for outputting a signal to control the operation of the air conditioner according to the reference temperature set by said variable resistor and the room temperature modified by said temperature modification circuit.
