There are different control modes for the ventilation control. The behavior is selectable by parameter and is dependent on if a room air quality sensor is available.

Ventilation mode can be set to the following:

  • Off
  • Minimum (Constant air flow)
  • Dcv (Demand controlled ventilation) 1)
  • Dcv & Min (Demand controlled ventilation with a minimum flow) 1)

1) DCV requires air quality sensor in the room

NOTE:
The VAV and FPB application templates have been pre-loaded with the ventilation mode and airflow minimum (AirFlMin) as shown in the table below. The parameters can be modified to meet job requirements.
If the default application does not meet job requirements, an application can be configured and modified to job specifications in ABT Site.
