This module monitors the airflow status and the fan command. If the fan is commanded on and the airflow status goes to a fault state, the fan alarm output is set to Alarm. The output remains in the Alarm state until manually reset.

The Fan Alarm module is used by the Unit Ventilator and Heat Pump applications when the user has requested that the Fan be locked off when a failure has been detected. When a fan failure is detected, the fan is locked off until a reset is received.

You can view and modify the modules in this group’s logic.
