This option is available if Return Fan is not selected. This option adds a BO for the Relief Fan start stop and an AO for the fan speed control. The only control strategy for this fan is to maintain building static pressure. The relief fan is controlled to maintain the building static pressure setpoint (the network input BLDGP-SP). This scheme maintains slight positive pressure in the building compared to the exterior static pressure.
