Abstract
In an electronic thermostatic circuit, a resistive bridge network is employed to sense the level of the ambient temperature. The bridge includes three legs having fixed resistors and one leg having a temperature sensitive resistor as well as a serially connected adjustable potentiometer. The adjustable potentiometer is adjustable to provide a selected set point for the operation of the thermostat within a given range of temperatures. The adjustable potentiometer is provided with a shaft to which an adjusting knob having a pointer thereon is secured by means of a slip fastener. Calibration of the assembly is accomplished by turning the knob with its pointer pointed in a preferred direction then holding the knob while adjusting the shaft and the associated potentiometer until the bridge output corresponds with the value indicated by knob pointer.
