ABSTRACT:
A controller for a system of the type including a variable temperature heat source arranged in heat exchange relation with a fluid circulating circuit, and a variable speed pump disposed in said circuit for varying the flow rate of fluid therethrough in response to variations in the temperature of the fluid. The controller includes a probe for sensing a temperature indicative of the temperature of the fluid in the circuit and for generating a first signal indicative thereof; means for generating a reference signal indicative of a predetermined temperature; means for comparing the first two signals and generating a third signal indicative of the difference therebetween; means responsive to the third signal for generating an analog control signal; means responsive to the analog control signal for varying the pump speed as a function of the control signal for equalizing the first and second signals.
