Abstract:
Apparatus and methods for Fault Detection Diagnostics (FDD) for a Heating, Ventilating, Air Conditioning (HVAC) system with an economizer to detect: 1) air temperature or relative humidity sensors failed/faulted, 2) dampers not modulating, 3) excessive outdoor air, 4) economizing when should not, 5) not economizing when should and 6) inadequate outdoor air. Economizer damper position is measured using at least one inertial Micro-Electro-Mechanical System (MEMS) device: 1) magnetometer, 2) accelerometer, 3) IMU and 4) rotatiometer. The magnetometer detects damper position using a small permanent-magnet attached to a movable damper and a MEMS device attached to the economizer frame. The accelerometer and IMU detect damper position using a MEMS device attached to the damper, and the ratiometer detects angular damper position. The methods determine whether or not the HVAC economizer, sensors, actuator and outdoor air dampers are functioning properly. If economizer faults are detected, then the method provides electronically-transmitted fault signals.

Claim (Index 3):
The apparatus of  claim 1 , wherein the apparatus provides additional FDD for the HVAC system with the economizer to detect:\n whether or not the sensor signal input provides a failed or faulted signal from the group consisting of:\n a floating signal, \n a grounded signal, \n a sensor measurement outside of a tolerance range selected from the group consisting of:\n an OAT less than \u221250 degrees Fahrenheit (\u00b0 F.) or greater than +140\u00b0 F., \n a RAT less than +50\u00b0 F. or greater than +120\u00b0 F., \n a MAT less than \u221250\u00b0 F. or greater than +140\u00b0 F., \n a SAT for cooling less than +33\u00b0 F. or greater than +120\u00b0 F., \n a SAT for heating less than +65\u00b0 F. or greater than +140\u00b0 F., and \n a RH less than 0% or greater than 100%; and \n \n if the sensor signal is failed or measurement is faulted, then the microprocessor provides a FDD alarm signal using a fault code, a signal, a text message, an email, or other information displayed on a standard thermostat, WIFI-enabled thermostat, internet-connected computer, internet telephony system, smart phone or internet software application to indicate a maintenance requirement to check the sensor.
