What is "Fault Detection Diagnosis"

Have you ever had a dashboard light turn on in your car?

These lights are your car's way of alerting you of faults within its system.

Using a code reader, mechanics can pinpoint the problem and offer a solution.

FDD works the same way!

Most rooftop air-conditioning units (RTUs) have one or more faults that can significantly effect system efficiency.
These faults at times could be catastrophic that result in costly equipment failures. 
Technicians can utilize real-time data collected from a series of sensors to detect faults, diagnose and fix the problems quickly.

What are the common faults?

Energy consumption

Economizers and ventilation

Pressurization

Pump and fan systems

Scheduling

Simultaneous heating and cooling 

What are the benefits of using FDD?

Automated fault detection and diagnosis (FDD) tools have the potential to save considerable energy for existing commercial RTUs, chillers and refrigeration systems.
With the installation of a fault detection and diagnostics system, building owners have the ability to easily maintain these systems, allowing them to operate more efficiently.
