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 16):
The method of  claim 14 , further including:\n monitoring the electrical signal output from the accelerometer or IMU sensor and determining whether or not the damper position is outside of at least one required tolerance causing a fault selected from the group consisting of:\n damper stuck in the closed position or stuck in an open position less than fully open during a call for cooling or heating causing a dampers not modulating fault, \n damper open to a position greater than the minimum position during the call for cooling and the Outdoor Air Temperature (OAT) does not allow economizer cooling causing an excessive outdoor air fault, \n damper open to a position greater than the minimum position during the call for heating causing the excessive outdoor air fault, \n damper fully open during the call for cooling and the OAT does not allow economizer cooling causing an economizing when should not fault, \n damper fully open during the call for heating causing the economizing when should not fault, \n damper not fully open during the call for cooling when OAT allows economizer cooling causing a not economizing when should fault, and \n damper not modulating to the correct position during the call for cooling when OAT allows economizer cooling causing a damper not modulating fault; and \n if the damper position is outside of the required tolerance, then reporting 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.
