Damper Factor
Setpoint: 40%
This setpoint is used when you have an EM1 Expansion Module
installed and confi 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 airfl ow through the Return Air Bypass Damper.
Increasing this percentage increases the airfl ow through the Return
Air Bypass Damper by causing the Return Air Damper to move fur-
ther towards its closed position in relation to the Return Air Bypass
Damper moving towards its open position.
