System and Method for Heating Ventilation and Air Conditioning Component Detection |
摘要 |
A method for detecting heating, ventilation, and air conditioning (HVAC) components is provided. The method includes the steps of measuring an initial current at a current sensor in a circuit, while a relay is de-energized; energizing the relay; measuring, at a periodic interval, an energized current while the relay is energized; incrementing a counter if an absolute difference between a first voltage related to the energized current and a second voltage related to the initial current is above a threshold; and determining a HVAC component is present if the counter exceeds a pre-determined value during a pre-determined time period.
