1. A system for displaying, on an electronic display device, scaled performance indicators of control applications in an environmental control system, the system comprising:
- a memory device configured to receive and store more than one performance indicator from a first control application, wherein the first control application includes a modulating control output to control a first device of the environmental control system, wherein the memory device is further configured to receive and store more than one performance indicator from a second control application, wherein the second control application includes a staged-control output to control a second device of the environmental control system; and
computing electronics configured to identify a probability distribution function, wherein the probability distribution function is a characteristic of a fault-free environmental control system, wherein the computing electronics are further configured to retrieve the performance indicators of the first and second control applications from the memory device and to calculate and store probability distributions associated with the performance indicators of the first and second control applications in the memory device, wherein the calculation is based on the identified probability distribution function, wherein the computing electronics are further configured to calculate a graphical representation of the probability distributions associated with the first and second control applications and to cause the display, on the electronic display device, of the graphical representation of the probability distributions on a common scale.

Abstract
A system is disclosed for scaling performance indicators of control applications in an environmental control system. The system is configured to identify a probability distribution that is characteristic of a fault-free environmental control system and to use the probability distribution of a fault-free environmental control system in calculations to display probability distributions of data from first and second control applications on a common scale.
