Description
The Carrier AW01DA053 Key is a miniature and portable sensor utilized in numerous HVAC tools. It commonly has the function of the ventilation of the entire system, so that it operates optimally and without unnecessary stress. The Key is designed to sense changes in pressure inside the HVAC system. With these changes sensed, it can tell how much air is passing through the system. The moment the Key perceives a change in pressure, it sends back a to the control board of the HVAC system. The board receives the signal from the Key and controls other parts of the system including dampers to control the flow of air in the system.
