The fan speed button at the room operator unit allows the occupant to increase the ventilation rate in the room when the room operating mode (ROpMod) is in Comfort. A request is sent to the plant operating mode (PltOpMod) to start the Rapid ventilation (RpdVnt) and improve the room air quality. Rapid ventilation utilizes the maximum air volume flow setpoint value for ventilation (VavSuAflMaxVnt).

The application templates have been configured with a 15 minute run-time for rapid ventilation. This function can be configured to meet job site requirements.

The rapid ventilation option on the room unit is displayed and enabled as a Fan. Pressing the button activates the Rapid Ventilation mode.
