Abstract

The regulating equipment comprises a regulating device (1) and a control device (2) connected thereto via two lines (6, 7). A sensor member (18) and a desired-value transmitter (20) in mutually parallel current paths (3, 4) which each contain a rectifier (17, 19) having mutually opposing forward directions, are each connected in series with a rectifier (17, 19) and are connected to the two lines (6 and 7), to which is also connected the drive (22) of a clock timer (5) for influencing the desired-value transmitter (20) in the control device (2). The two lines (6, 7) are connected in the regulating device (1) via the series connection of an AC voltage source (8, 14) and a capacitor (12) to one another. The capacitor (12) is connected to two inputs (10, 11) of an amplifier (9), which responds only to the different magnitude of the current half-waves, which are poled in opposition to one another, and operate an actuator. The clock timer drive is provided by a synchronous motor (22) or a DC drive fed via a bridge rectifier. The sensor member is a temperature sensor (18). This design permits the simultaneous transmission over two lines of the continuous signals from the sensor and desired-value transmitter and of the supply current for the clock timer motor.
