This switch monitors the pressure differential across the air metering orifice to verify adequate combustion airflow before ignition can proceed. Once the blower generates sufficient air movement, the AFS closes its contacts, completing the circuit to the hot surface igniter (HSI) and initiating the fuel

I've been searching for cooling pillowcases for a long time. None ever seemed to fit the bill until I found these. Now, let's be clear, they are cool to sleep on for a good amount of time, but you will have to flip them occasionally throughout the night to keep getting that cold feeling. All in all, as a person whose face runs hot when I sleep, these cases have made my nights more bearable, and I do believe they are helping with my skin issues. As far as good value for the money, I think they are a little costly. Color was comparable to the online photo.
