<p>PURPOSE:To prevent a room temperature to be finally controlled from being affected by an initial room temperature and retard an excessive demand for the heating unit by a method wherein a room temperature control device is controlled under a composite output of room temperature sensing means and hot water temperature sensing means. CONSTITUTION:A heat exchanger unit 2 is arranged in the room 1 in which temperature is controlled, and water controlled at a desired temp. is fed to the heat exchanger unit, thereby the temperature in the room is controlled. In a temperature adjuster unit applied in the room temperature control unit, the temperature in the room is sensed by the room temperature sensing means 6 and the temperature of water to be supplied to the device 2 is sensed by the water temperature sensing means 7. Further, both an output from means 6 and an output from means 7 are combined and fed to one of the input portions of the voltage comparison circuit 13, a reference voltage is applied to the other input of the circuit 13 and the room temperature control device is controlled with an output from the circuit 13. That is, the room temperature is not affected by the initial room temperature and controlled to have a desired value, and the water temperature is also controlled so as not to be elevated above a desired value.</p> |
