Controlling Airflow with an AFMS  

About  

After Setting Up an AFMS on page 4, you can control outside air flow, or control mixed air temperature. Also, for  

setup or maintenance purposes, you can command a damper position.  

Alternatively, you can pass through control of the damper actuator to an external controller, using the AFMS for  

measurement and monitoring only. (See Monitoring with an AFMS on page 13.)  

Controlling Outside Air Flow  

Select the Configure tab.

4.  

From the Control Mode dropdown menu, select OA FLOW CTRL.  

Enter an Outside Air Flow Setpoint (as CFM).  

Select Save.  

Note: The outside air damper will modulate to maintain the Outside Air Flow Setpoint. If Enable Low Limit  

is ON and the mixed air temperature reaches the Low Temp Limit, the damper will modulate toward  

closed to prevent freezing of the equipment. If an occupancy sensor is used, this Control Mode will only be  

active when the served space is occupied.  

Controlling Mixed Air Temperature  

From the tabs that appear, select Configure.  

From the Control Mode dropdown menu, select MAT CTRL.
