摘要
A building temp. control device with a comparison circuit arrangement contg. an exterior wall (weather) temp. sensor (5), a solar ray incidence temp. sensor (9), and an input temp. sensor (15), uses temp. dependent resistance sensors. - The temp. sensors (5, 9, 15) are connected in series with comparison resistors (18, 20, 19). The series pairs of temp. sensors and comparison resistors are connected in parallel as arms of a Wheatstone bridge. A potentiometer (21) joins two junctions of the pairs (9, 20; 5, 18). Its output is connected via a further potentiometer to the input sensor (15) junction. The second potentiometer output (14) and that (13) of the third potentiometer (16) in the fixed arm are the comparison circuit outputs.
