Return Air Bypass
Damper Factor
Setpoint: 0%
This setpoint is used when your HVAC unit is con
fi
gured for Return
Air Bypass Damper control. The Return Air Bypass Damper Factor
Setpoint is a percentage value that is used to calculate the Return Air
Damper position in relation to the Return Air Bypass Damper position.
This provides a method for adjusting the air
fl
ow through the Return
Air Bypass Damper.
Increasing this percentage increases the air
fl
ow through the Return Air
Bypass Damper by causing the Return Air Damper to move further
towards its closed position in relation to the Return Air Bypass Damper
moving towards its open position.
