.Buildings.Templates.Plants.Controls.MinimumFlow.Controller

Information

The minimum flow bypass valve is modulated based on a reverse acting control loop to maintain the primary flow rate at setpoint. The setpoint is calculated as described in Buildings.Templates.Plants.Controls.MinimumFlow.Setpoint.

When using isolation valve command signals (have_valInlIso=true or have_valOutIso=true): When any valve is commanded open, the bypass valve control loop is enabled. The valve is opened 100 % otherwise. When enabled, the bypass valve loop shall be biased to start with the valve 100 % open.

Otherwise (have_valInlIso=false and have_valOutIso=false): When any primary pump is proven on, the bypass valve control loop is enabled. The valve is opened 100 % otherwise. When enabled, the bypass valve loop shall be biased to start with the valve 100 % open.
