ABSTRACT:
A circuit containing a plurality of fixed detector resistors and a detector potentiometer, each being representative of the contribution to energy consumption of a different operator controllable parameter of an air conditioner and being series connected with one another across a d.c. galvanometer and meter sensitivity resistor. Shorting switches are connected across each of the detector resistors, the conditions of which switches are responsive to the conditions of corresponding switchable parameters such as fan speed, vent door position, etc. A slide arm of the potentiometer is responsive to thermostat operating temperature setting. The resistance values of each detector resistor and the potentiometer are selected to contribute approximately the same percentage resistance to the total resistance of the detectors as a change in the status of its corresponding control parameter contributes to air conditioner operating cost efficiency. The meter provides an analog display of long term energy consumption and energy changes caused by changes in the control parameters.
