This module monitors the status of the Airflow Proving Switch as compared to the commanded Fan Mode. The module adds some error checking to remove short glitches in the signal and also indicates a fault should the fan command be on for a length of time without any indication of proof of flow.

You can view and modify the modules in this group’s logic, but the Airflow Proving FSM contained within cannot be modified. For information on how the FSM determines the state, see FSM (Flow Status Determination).
