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 4):
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 electrical signal input from the damper position sensor determines the absolute position of the damper is outside of at least one required tolerance causing a fault selected from the group consisting of:\n call for cooling or heating and the damper is stuck in the closed position or stuck in an open position less than fully open causing a dampers not modulating fault, \n call for cooling and OAT does not allow economizer cooling and the damper is open to a position greater than the minimum position causing an excessive outdoor air fault, \n call for heating and the damper is open to a position greater than the minimum position causing the excessive outdoor air fault, \n call for cooling and OAT does not allow economizer cooling and the damper is fully open causing an economizing when should not fault, \n call for heating and the damper is damper is fully open causing the economizing when should not fault, \n call for cooling and OAT allows economizer cooling and the damper is not fully open causing a not economizing when should fault, and \n call for cooling and OAT allows economizer cooling and the damper is not modulating to the correct position causing a not modulating fault; and \n if the damper position is outside of the required tolerance, then the microprocessor generates 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 economizer, the actuator, or the damper.
