ABSTRACT:
A temperature control device of a heating apparatus comprising: an input unit for receiving input of a set temperature; a heating/cooling unit for raising/dropping temperature of a medium, from which a person receives heat; a set temperature reaching unit for controlling the heating/cooling unit so that temperature of the medium is raised to the set temperature and maintained afterwards; a time judgement unit for judging whether a given time has passed after the temperature of the medium is raised to the set temperature; and an imperceptible temperature change unit for controlling the heating/cooling unit, if the time judgement unit judges that the given time has passed, so that the temperature of the medium drops/rises by an amount within a given range by which human beings cannot perceive changes in temperature at a temperature change rate by which human beings cannot perceive changes in temperature.
According to the temperature control device, after a person sets a room temperature, it drops/rises by an amount which cannot be perceived by the person during heating/cooling.
