Abstract

The control circuit is intended for air conditioning plant or for temperature control systems. A temperature sensor is fed with the required input value and is connected to a temperature controller (9) and this produces a control voltage (Us1) at the input to the control drive unit (7). The control voltage is applied to an adder (21) along with a signal from a voltage divider (U, 17) and a variable potential (Us2, 11) arriving from a sensor in a freezing point detector on the output of a heat exchanger. The control signal from the adder (21) operates an electro-mechanical converter (22) with a mechanical output (y) connected to the mixer valve on the hot water inlet circuit to the heat exchanger.
