The concept of fault detection and diagnostics (FDD) is often compared to the “check engine light” on your car. In the automotive example, the engine computers check constantly for problems related to safety, performance, and efficiency, and when an error is detected, the check engine light comes on. The driver is then supposed to take the car to a mechanic who can read the code and ideally remedy the problem. Some car manufacturers take this a step further and electronically transmit and analyze the data.
Bringing FDD information from HVAC equipment into the BAS provides building owners with the ability to see and solve problems before they result in problems related to comfort, performance, and efficiency.
