Title:
TEMPERATURE CONTROLLER
Document Type and Number:
Japanese Patent JPS57172419
Kind Code:
A
Abstract:
PURPOSE:To prevent air-conditioned space from being warmed up too much by finding the criterion of room temperature which is regarded as the best one for floor temperature set by a user, and then attracting a user's attention to the change or confirmation of the room temperature by an annunciating means when the room temperature rises above the criterion. CONSTITUTION:When a user operates a temperature regulator 2 to set desired floor temperature, a floor temperature control circuit 5 compares the temperature of a floor temperature thermistor 1 with the set temperature and then controls a load switching device 4 to regulates the floor temperature to that set by the temperature regulator 2. A room temperature setting circuit 7 sets room temperature according to floor temperature-room temperature characteristics on the basis of the floor temperature set by the regulator 2. An annunciation discriminating circuit 9 compares the temperature of a room temperature thermistor 6 with the temperature set by the room temperature setting circuit 7 and then when the room temperature rises above that by the circuit 7, an annunciating device 8 such as a lamp calls a user's attention to the change of room temperature.
